+Help!! Synapse eats all my RAM!
+===============================
+
+Synapse's architecture is quite RAM hungry currently - we deliberately
+cache a lot of recent room data and metadata in RAM in order to speed up
+common requests.  We'll improve this in future, but for now the easiest
+way to either reduce the RAM usage (at the risk of slowing things down)
+is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
+variable.  Roughly speaking, a SYNAPSE_CACHE_FACTOR of 1.0 will max out
+at around 3-4GB of resident memory - this is what we currently run the
+matrix.org on.  The default setting is currently 0.1, which is probably
+around a ~700MB footprint.  You can dial it down further to 0.02 if
+desired, which targets roughly ~512MB.  Conversely you can dial it up if
+you need performance for lots of users and have a box with a lot of RAM.

+Replication Architecture
+========================
+
+Motivation
+----------
+
+We'd like to be able to split some of the work that synapse does into multiple
+python processes. In theory multiple synapse processes could share a single
+postgresql database and we'd scale up by running more synapse processes.
+However much of synapse assumes that only one process is interacting with the
+database, both for assigning unique identifiers when inserting into tables,
+notifying components about new updates, and for invalidating its caches.
+
+So running multiple copies of the current code isn't an option. One way to
+run multiple processes would be to have a single writer process and multiple
+reader processes connected to the same database. In order to do this we'd need
+a way for the reader process to invalidate its in-memory caches when an update
+happens on the writer. One way to do this is for the writer to present an
+append-only log of updates which the readers can consume to invalidate their
+caches and to push updates to listening clients or pushers.
+
+Synapse already stores much of its data as an append-only log so that it can
+correctly respond to /sync requests so the amount of code changes needed to
+expose the append-only log to the readers should be fairly minimal.
+
+Architecture
+------------
+
+The Replication API
+~~~~~~~~~~~~~~~~~~~
+
+Synapse will optionally expose a long poll HTTP API for extracting updates. The
+API will have a similar shape to /sync in that clients provide tokens
+indicating where in the log they have reached and a timeout. The synapse server
+then either responds with updates immediately if it already has updates or it
+waits until the timeout for more updates. If the timeout expires and nothing
+happened then the server returns an empty response.
+
+However unlike the /sync API this replication API is returning synapse specific
+data rather than trying to implement a matrix specification. The replication
+results are returned as arrays of rows where the rows are mostly lifted
+directly from the database. This avoids unnecessary JSON parsing on the server
+and hopefully avoids an impedance mismatch between the data returned and the
+required updates to the datastore.
+
+This does not replicate all the database tables as many of the database tables
+are indexes that can be recovered from the contents of other tables.
+
+The format and parameters for the api are documented in
+``synapse/replication/resource.py``.
+
+
+The Slaved DataStore
+~~~~~~~~~~~~~~~~~~~~
+
+There are read-only version of the synapse storage layer in
+``synapse/replication/slave/storage`` that use the response of the replication
+API to invalidate their caches.

+URL Previews
+============
+
+Design notes on a URL previewing service for Matrix:
+
+Options are:
+
+ 1. Have an AS which listens for URLs, downloads them, and inserts an event that describes their metadata.
+   * Pros:
+     * Decouples the implementation entirely from Synapse.
+     * Uses existing Matrix events & content repo to store the metadata.
+   * Cons:
+     * Which AS should provide this service for a room, and why should you trust it?
+     * Doesn't work well with E2E; you'd have to cut the AS into every room
+     * the AS would end up subscribing to every room anyway.
+
+ 2. Have a generic preview API (nothing to do with Matrix) that provides a previewing service:
+   * Pros:
+     * Simple and flexible; can be used by any clients at any point
+   * Cons:
+     * If each HS provides one of these independently, all the HSes in a room may needlessly DoS the target URI
+     * We need somewhere to store the URL metadata rather than just using Matrix itself
+     * We can't piggyback on matrix to distribute the metadata between HSes.
+
+ 3. Make the synapse of the sending user responsible for spidering the URL and inserting an event asynchronously which describes the metadata.
+   * Pros:
+     * Works transparently for all clients
+     * Piggy-backs nicely on using Matrix for distributing the metadata.
+     * No confusion as to which AS
+   * Cons:
+     * Doesn't work with E2E
+     * We might want to decouple the implementation of the spider from the HS, given spider behaviour can be quite complicated and evolve much more rapidly than the HS.  It's more like a bot than a core part of the server.
+
+ 4. Make the sending client use the preview API and insert the event itself when successful.
+   * Pros:
+      * Works well with E2E
+      * No custom server functionality
+      * Lets the client customise the preview that they send (like on FB)
+   * Cons:
+      * Entirely specific to the sending client, whereas it'd be nice if /any/ URL was correctly previewed if clients support it.
+
+ 5. Have the option of specifying a shared (centralised) previewing service used by a room, to avoid all the different HSes in the room DoSing the target.
+
+Best solution is probably a combination of both 2 and 4.
+ * Sending clients do their best to create and send a preview at the point of sending the message, perhaps delaying the message until the preview is computed?  (This also lets the user validate the preview before sending)
+ * Receiving clients have the option of going and creating their own preview if one doesn't arrive soon enough (or if the original sender didn't create one)
+
+This is a bit magical though in that the preview could come from two entirely different sources - the sending HS or your local one.  However, this can always be exposed to users: "Generate your own URL previews if none are available?"
+
+This is tantamount also to senders calculating their own thumbnails for sending in advance of the main content - we are trusting the sender not to lie about the content in the thumbnail.  Whereas currently thumbnails are calculated by the receiving homeserver to avoid this attack.
+
+However, this kind of phishing attack does exist whether we let senders pick their thumbnails or not, in that a malicious sender can send normal text messages around the attachment claiming it to be legitimate.  We could rely on (future) reputation/abuse management to punish users who phish (be it with bogus metadata or bogus descriptions).   Bogus metadata is particularly bad though, especially if it's avoidable.
+
+As a first cut, let's do #2 and have the receiver hit the API to calculate its own previews (as it does currently for image thumbnails).  We can then extend/optimise this to option 4 as a special extra if needed.
+
+API

+* Downloads the URL
+  * If HTML, just stores it in RAM and parses it for OG meta tags
+    * Download any media OG meta tags to the media repo, and refer to them in the OG via mxc:// URIs.
+  * If a media filetype we know we can thumbnail: store it on disk, and hand it to the thumbnailer. Generate OG meta tags from the thumbnailer contents.
+  * Otherwise, don't bother downloading further.
