* Store state groups separately from events (#2784)Erik Johnston2018-02-061-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Split state group persist into seperate storage func * Add per database engine code for state group id gen * Move store_state_group to StateReadStore This allows other workers to use it, and so resolve state. * Hook up store_state_group * Fix tests * Rename _store_mult_state_groups_txn * Rename StateGroupReadStore * Remove redundant _have_persisted_state_group_txn * Update comments * Comment compute_event_context * Set start val for state_group_id_seq ... otherwise we try to recreate old state groups * Update comments * Don't store state for outliers * Update comment * Update docstring as state groups are ints

| | | | I found myself wishing we had this.
* Fix some logcontext leaks in replication resourceRichard van der Hoff2017-11-231-2/+4
| | | | | The @measure_func annotations rely on the wrapped function respecting the logcontext rules. Add the necessary yields to make this work.
* Pull out bits of StateStore to a mixinRichard van der Hoff2017-11-141-33/+6
| | | | | | | | | ... so that we don't need to secretly gut-wrench it for use in the slaved stores. I haven't done the other stores yet, but we should. I'm tired of the workers breaking every time we tweak the stores because I forgot to gut-wrench the right method. fixes https://github.com/matrix-org/synapse/issues/2655.
* Make __init__ consitstent across Store heirarchyRichard van der Hoff2017-11-131-1/+1
| | | | | | Add db_conn parameters to the `__init__` methods of the *Store classes, so that they are all consistent, which makes the multiple inheritance work correctly (and so that we can later extract mixins which can be used in the slavedstores)

| * Reduce federation presence replication trafficErik Johnston2017-04-101-0/+1
| | | | | | | | | | | | | | | | This is mainly done by moving the calculation of where to send presence updates from the presence handler to the transaction queue, so we only need to send the presence event (and not the destinations) across the replication connection. Before we were duplicating by sending the full state across once per destination.

* Use presence replication stream to invalidate cacheErik Johnston2017-03-241-0/+1
| | | | | | Instead of using the cache invalidation replication stream to invalidate the _get_presence_cache, we can instead rely on the presence replication stream. This reduces the amount of replication traffic considerably.

* Reduce DB hits for replicationErik Johnston2016-09-231-36/+103
| | | | | | | | | | | | | | Some streams will occaisonally advance their positions without actually having any new rows to send over federation. Currently this means that the token will not advance on the workers, leading to them repeatedly sending a slightly out of date token. This in turns requires the master to hit the DB to check if there are any new rows, rather than hitting the no op logic where we check if the given token matches the current token. This commit changes the API to always return an entry if the position for a stream has changed, allowing workers to advance their tokens correctly.

synapse This is necessary for replicating the data in synapse to be visible to a separate service because presence and typing notifications aren't stored in a database so won't be visible to another process. This API can be used to either get the raw data by requesting the tables themselves or to just receive notifications for updates by following the streams meta-stream. Returns updates for each table requested a JSON array of arrays with a row for each row in the table. Each table is prefixed by a header row with the: name of the table, current stream_id position for the table, number of rows, number of columns and the names of the columns. This is followed by the rows that have been added to the server since the requester last asked. The API has a timeout and is hooked up to the notifier so that a slave can long poll for updates.
