-Scaling guide
-=============
-
-Our :ref:`installation guide <installation>` only covers "small-scale" setups, by which we mostly mean
-setups that run on a **single (virtual) machine** and do not encounter large traffic peaks.
-
-We do not offer an installation guide for larger-scale setups of pretix, mostly because we believe that
-there is no one-size-fits-all solution for this and the desired setup highly depends on your use case,
-the platform you run pretix on, and your technical capabilities. We do not recommend trying set up pretix
-in a multi-server environment if you do not already have experience with managing server clusters.
-
-This document is intended to give you a general idea on what issues you will encounter when you scale up
-and what you should think of.
-
-.. tip::
-
-   If you require more help on this, we're happy to help. Our pretix Enterprise support team has built
-   and helped building, scaling and load-testing pretix installations at any scale and we're looking
-   forward to work with you on fine-tuning your system. If you intend to sell **more than a thousand
-   tickets in a very short amount of time**, we highly recommend reaching out and at least talking this
-   through. Just get in touch at sales@pretix.eu!
-
-Scaling reasons
----------------
-
-There's mainly two reasons to scale up a pretix installation beyond a single server:
-
-* **Availability:** Distributing pretix over multiple servers can allow you to survive failure of one or more single machines, leading to a higher uptime and reliability of your system.
-
-* **Traffic and throughput:** Distributing pretix over multiple servers can allow you to process more web requests and ticket sales at the same time.
-
-You are very unlikely to require scaling for other reasons, such as having too much data in your database.
-
-Components
-----------
-
-A pretix installation usually consists of the following components which run performance-relevant processes:
-
-* ``pretix-web`` is the Django-based web application that serves all user interaction.
-
-* ``pretix-worker`` is a Celery-based application that processes tasks that should be run asynchronously outside of the web application process.
-
-* A **SQL database** keeps all the important data and processes the actual transactions. We recommend using PostgreSQL, but MySQL/MariaDB works as well.
-
-* A **web server** that terminates TLS and HTTP connections and forwards them to ``pretix-web``. In some cases, e.g. when serving static files, the web servers might return a response directly. We recommend using ``nginx``.
-
-* A **redis** server responsible for the communication between ``pretix-web`` and ``pretix-worker``, as well as for caching.
-
-* A directory of **media files** such as user-uploaded files or generated files (tickets, invoices, …) that are created and used by ``pretix-web``, ``pretix-worker`` and the web server.
-
-In the following, we will discuss the scaling behavior of every component individually. In general, you can run all of the components
-on the same server, but you can just as well distribute every component to its own server, or even use multiple servers for some single
-components.
-
-.. warning::
-
-   When setting up your system, don't forget about security. In a multi-server environment,
-   you need to take special care to ensure that no unauthorized access to your database
-   is possible through the network and that it's not easy to wiretap your connections. We
-   recommend a rigorous use of firewalls and encryption on all communications. You can
-   ensure this either on an application level (such as using the TLS support in your
-   database) or on a network level with a VPN solution.
-
-Web server
-""""""""""
-
-Your web server is at the very front of your installation. It will need to absorb all of the traffic, and it should be able to
-at least show a decent error message, even when everything else fails. Luckily, web servers are really fast these days, so this
-can be achieved without too much work.
-
-We recommend reading up on tuning your web server for high concurrency. For nginx, this means thinking about the number of worker
-processes and the number of connections each worker process accepts. Double-check that TLS session caching works, because TLS
-handshakes can get really expensive.
-
-During a traffic peak, your web server will be able to make us of more CPU resources, while memory usage will stay comparatively low,
-so if you invest in more hardware here, invest in more and faster CPU cores.
-
-Make sure that pretix' static files (such as CSS and JavaScript assets) as well as user-uploaded media files (event logos, etc)
-are served directly by your web server and your web server caches them in-memory (nginx does it by default) and sets useful
-headers for client-side caching. As an additional performance improvement, you can turn of access logging for these types of files.
-If you want, you can even farm out serving static files to a different web server entirely and :ref:`configure pretix to reference
-them from a different URL <config-urls>`.
-
-.. tip::
-
-   If you expect *really high traffic* for your very popular event, you might want to do some rate limiting on this layer, or,
-   if you want to ensure a fair and robust first-come-first-served experience and prefer letting users wait over showing them
-   errors, consider a queuing solution. We're happy to provide you with such systems, just get in touch at sales@pretix.eu.
-
-pretix-web
-""""""""""
-
-The ``pretix-web`` process does not carry any internal state can be easily started on as many machines as you like, and you can
-use the load balancing features of your frontend web server to redirect to all of them.
-
-You can adjust the number of processes in the ``gunicorn`` command line, and we recommend choosing roughly two times the number
-of CPU cores available. Under load, the memory consumption of ``pretix-web`` will stay comparatively constant, while the CPU usage
-will increase a lot. Therefore, if you can add more or faster CPU cores, you will be able to serve more users.
-
-pretix-worker
-"""""""""""""
-
-The ``pretix-worker`` process performs all operations that are not directly executed in the request-response-cycle of ``pretix-web``.
-Just like ``pretix-web`` you can easily start up as many instances as you want on different machines to share the work. As long as they
-all talk to the same redis server, they will all receive tasks from ``pretix-web``, work on them and post their result back.
-You can configure the number of threads that run tasks in parallel through the ``--concurrency`` command line option of ``celery``.
-
-Just like ``pretix-web``, this process is mostly heavy on CPU, disk IO and network IO, although memory peaks can occur e.g. during the
-generation of large PDF files, so we recommend having some reserves here.
-
-``pretix-worker`` performs a variety of tasks which are of different importance.
-Some of them are mission-critical and need to be run quickly even during high load (such as
-creating a cart or an order), others are irrelevant and can easily run later (such as
-distributing tickets on the waiting list). You can fine-tune the capacity you assign to each
-of these tasks by running ``pretix-worker`` processes that only work on a specific **queue**.
-For example, you could have three servers dedicated only to process order creations and one
-server dedicated only to sending emails. This allows you to set priorities and also protects
-you from e.g. a slow email server lowering your ticket throughput.
-
-You can do so by specifying one or more queues on the ``celery`` command line of this process, such as ``celery -A pretix.celery_app worker -Q notifications,mail``. Currently,
-the following queues exist:
-
-* ``checkout`` -- This queue handles everything related to carts and orders and thereby everything required to process a sale. This includes adding and deleting items from carts as well as creating and canceling orders.
-
-* ``mail`` -- This queue handles sending of outgoing emails.
-
-* ``notifications`` -- This queue handles the processing of any outgoing notifications, such as email notifications to admin users (except for the actual sending) or API notifications to registered webhooks.
-
-* ``background`` -- This queue handles tasks that are expected to take long or have no human waiting for their result immediately, such as refreshing caches, re-generating CSS files, assigning tickets on the waiting list or parsing bank data files.
-
-* ``default`` -- This queue handles everything else with "medium" or unassigned priority, most prominently the generation of files for tickets, invoices, badges, admin exports, etc.
-
-Media files
-"""""""""""
-
-Both ``pretix-web``, ``pretix-worker`` and in some cases your webserver need to work with
-media files. Media files are all files generated *at runtime* by the software. This can
-include files uploaded by the event organizers, such as the event logo, files uploaded by
-ticket buyers (if you use such features) or files generated by the software, such as
-ticket files, invoice PDFs, data exports or customized CSS files.
-
-Those files are by default stored to the ``media/`` sub-folder of the data directory given
-in the ``pretix.cfg`` configuration file. Inside that ``media/`` folder, you will find a
-``pub/`` folder containing the subset of files that should be publicly accessible through
-the web server. Everything else only needs to be accessible by ``pretix-web`` and
-``pretix-worker`` themselves.
-
-If you distribute ``pretix-web`` or ``pretix-worker`` across more than one machine, you
-**must** make sure that they all have access to a shared storage to read and write these
-files, otherwise you **will** run into errors with the user interface.
-
-The easiest solution for this is probably to store them on a NFS server that you mount
-on each of the other servers.
-
-Since we use Django's file storage mechanism internally, you can in theory also use a object-storage solution like Amazon S3, Ceph, or Minio to store these files, although we currently do not expose this through pretix' configuration file and this would require you to ship your own variant of ``pretix/settings.py`` and reference it through the ``DJANGO_SETTINGS_MODULE`` environment variable.
-
-At pretix.eu, we use a custom-built `object storage cluster`_.
-
-SQL database
-""""""""""""
-
-One of the most critical parts of the whole setup is the SQL database -- and certainly the
-hardest to scale. Tuning relational databases is an art form, and while there's lots of
-material on it on the internet, there's not a single recipe that you can apply to every case.
-
-As a general rule of thumb, the more resources you can give your databases, the better.
-Most databases will happily use all CPU cores available, but only use memory up to an amount
-you configure, so make sure to set this memory usage as high as you can afford. Having more
-memory available allows your database to make more use of caching, which is usually good.
-
-Scaling your database to multiple machines needs to be treated with great caution. It's a
-good to have a replica of your database for availability reasons. In case your primary
-database server fails, you can easily switch over to the replica and continue working.
-
-However, using database replicas for performance gains is much more complicated. When using
-replicated database systems, you are always trading in consistency or availability to get
-additional performance and the consequences of this can be subtle and it is important
-that you have a deep understanding of the semantics of your replication mechanism.
-
-.. warning::
-
-   Using an off-the-shelf database proxy solution that redirects read queries to your
-   replicas and write queries to your primary database **will lead to very nasty bugs.**
-
-   As an example, if you buy a ticket, pretix first needs to calculate how many tickets
-   are left to sell. If this calculation is done on a database replica that lags behind
-   even for fractions of a second, the decision to allow selling the ticket will be made
-   on out-of-data data and you can end up with more tickets sold than configured. Similarly,
-   you could imagine situations leading to double payments etc.
-
-If you do have a replica, you *can* tell pretix about it :ref:`in your configuration <config-replica>`.
-This way, pretix can offload complex read-only queries to the replica when it is safe to do so.
-As of pretix 2.7, this is mainly used for search queries in the backend and for rendering the
-product list and event lists in the frontend, but we plan on expanding this in the future.
-
-Therefore, for now our clear recommendation is: Try to scale your database vertically and put
-it on the most powerful machine you have available.
-
-redis
-"""""
-
-While redis is a very important part that glues together some of the components, it isn't used
-heavily and can usually handle a fairly large pretix installation easily on a single modern
-CPU core.
-Having some memory available is good in case of e.g. lots of tasks queuing up during a traffic peak, but we wouldn't expect ever needing more than a gigabyte of it.
-
-Feel free to set up a redis cluster for availability – but you won't need it for performance in a long time.
-
-The limitations
----------------
-
-Up to a certain point, pretix scales really well. However, there are a few things that we consider
-even more important than scalability, and those are correctness and reliability. We want you to be
-able to trust that pretix will not sell more tickets than you intended or run into similar error
-cases.
-
-Combined with pretix' flexibility and complexity, especially around vouchers and quotas, this creates
-some hard issues. In many cases, we need to fall back to event-global locking for some actions which
-are likely to run with high concurrency and cause harm.
-
-For every event, only one of these locking actions can be run at the same time. Examples for this are
-adding products limited by a quota to a cart, adding items to a cart using a voucher or placing an order
-consisting of cart positions that don't have a valid reservation for much longer. In these cases, it is
-currently not realistically possible to exceed selling **approx. 500 orders per minute per event**, even
-if you add more hardware.
-If you have an unlimited number of tickets, we can apply fewer locking and we've reached **approx.
-1500 orders per minute per event** in benchmarks, although even more should be possible.
-
-We're working to reduce the number of cases in which this is relevant and thereby improve the possible
-throughput. If you want to use pretix for an event with 10,000+ tickets that are likely to be sold out
-within minutes, please get in touch to discuss possible solutions. We'll work something out for you!

-Idempotency
------------
-
-Our API supports an idempotency mechanism to make sure you can safely retry operations without accidentally performing
-them twice. This is useful if an API call experiences interruptions in transit, e.g. due to a network failure, and you
-do not know if it completed successfully.
-
-To perform an idempotent request, add a ``X-Idempotency-Key`` header with a random string value (we recommend a version
-4 UUID) to your request. If we see a second request with the same ``X-Idempotency-Key`` and the same ``Authorization``
-and ``Cookie`` headers, we will not perform the action for a second time but return the exact same response instead.
-
-Please note that this also goes for most error responses. For example, if we returned you a ``403 Permission Denied``
-error and you retry with the same ``X-Idempotency-Key``, you will get the same error again, even if you were granted
-permission in the meantime! This includes internal server errors on our side that might have been fixed in the meantime.
-
-There are only three exceptions to the rule:
-
-* Responses with status code ``409 Conflict`` are not cached. If you send the request again, it will be executed as a
-  new request, since these responses are intended to be retried.
-
-* Rate-limited responses with status code ``429 Too Many Requests`` are not cached and you can safely retry them.
-
-* Responses with status code ``503 Service Unavailable`` are not cached and you can safely retry them.
-
-If you send a request with an ``X-Idempotency-Key`` header that we have seen before but that has not yet received a
-response, you will receive a response with status code ``409 Conflict`` and are asked to retry after five seconds.
-
-We store idempotency keys for 24 hours, so you should never retry a request after a longer time period.
-
-All ``POST``, ``PUT``, ``PATCH``, or ``DELETE`` api calls support idempotency keys. Adding an idempotency key to a
-``GET``, ``HEAD``, or ``OPTIONS`` request has no effect.

 If you want to limit the number of student tickets to 50 to ensure a certain minimum revenue, but do not want to limit the number of regular tickets artificially, we suggest you to create the same quota of 200 that is linked to both products, and then create a **second quota** of 50 that is only linked to the student ticket. This way, the system will reduce both quotas whenever a student ticket is sold and only the larger quota when a regular ticket is sold.

 Create three products (e.g. "super early bird", "early bird", "regular ticket") with the respective prices and one shared quota of your total event capacity. Then, set the **available from** and **available until** configuration fields of the products to automatically turn them on and off based on the current date.
 
-Use case: Early-bird tiers based on ticket numbers
---------------------------------------------------
+.. note::
 
-Let's say you run a conference with 400 tickets that has the following pricing scheme:
-
-* First 100 tickets ("super early bird"): € 450
-* Next 100 tickets ("early bird"): € 550
-* Remaining tickets ("regular"): € 650
-
-First of all, create three products:
-
-* "Super early bird ticket"
-* "Early bird ticket"
-* "Regular ticket"
-
-Then, create three quotas:
-
-* "Super early bird" with a **size of 100** and the "Super early bird ticket" product selected. At "Advanced options",
-  select the box "Close this quota permanently once it is sold out".
-
-* "Early bird and lower" with a **size of 200** and both of the "Super early bird ticket" and "Early bird ticket"
-  products selected. At "Advanced options", select the box "Close this quota permanently once it is sold out".
-
-* "All participants" with a **size of 400**, all three products selected and **no additional options**.
-
-Next, modify the product "Regular ticket". In the section "Availability", you should look for the option "Only show
-after sellout of" and select your quota "Early bird and lower". Do the same for the "Early bird ticket" with the quota
-"Super early bird ticket".
-
-This will ensure the following things:
-
-* Each ticket level is only visible after the previous level is sold out.
-
-* As soon as one level is really sold out, it's not coming back, because the quota "closes", i.e. locks in place.
-
-* By creating a total quota of 400 with all tickets included, you can still make sure to sell the maximum number of
-  tickets, even if e.g. early-bird tickets are canceled.
-
-Optionally, if you want to hide the early bird prices once they are sold out, go to "Settings", then "Display" and
-select "Hide all products that are sold out". Of course, it might be a nice idea to keep showing the prices to remind
-people to buy earlier next time ;)
-
-Please note that there might be short time intervals where the prices switch back and forth: When the last early bird
-tickets are in someone's cart (but not yet sold!), the early bird tickets will show as "Reserved" and the regular
-tickets start showing up. However, if the customers holding the reservations do not complete their order,
-the early bird tickets will become available again. This is not avoidable if we want to prevent malicious users
-from blocking all the cheap tickets without an actual sale happening.
+   pretix currently can't do early-bird tiers based on **ticket number** instead of time. We're planning this feature for later in 2019. For now, you'll need to monitor that manually.

 When running a conference, you might also organize a number of workshops with smaller capacity. To be able to plan, it would be great to know which workshops an attendee plans to attend.

 Your first and simplest option is to just create a multiple-choice question. This has the upside of making it easy for users to change their mind later on, but will not allow you to restrict the number of attendees signing up for a given workshop – or even charge extra for a given workshop.
 
-Option B: Add-on products with fixed time slots

-| 16:00-18:00 |            | Talk 4    |
-+-------------+------------+-----------+
-
-In this case, we recommend that you go to *Settings*, then *Plugins* and activate the plugin **Agenda constraints**.
-
-Then, create a product (without variations) for every single part that should be bookable (talks 1-4 and long workshops
-1 and 2) as well as appropriate quotas for each of them.
-
-All of these products should be part of the same category. In your base product (e.g. your conference ticket), you
-can then create an add-on product configuration allowing users to add products from this category.
-
-If you edit these products, you will be able to enter the "Start date" and "End date" of the talk or workshop close
-to the bottom of the page. If you fill in these values, pretix will automatically ensure no overlapping talks are
-booked.
