PDO EventStore implementation for Prooph EventStore

• PHP >= 7.3
• PDO_MySQL Extension or PDO_PGSQL Extension

For MariaDB you need server version >= 10.2.11.
Performance Impact: see [MariaDB Indexes and Efficiency](docs/variants.md#MariaDB Indexes and Efficiency)

For MySQL you need server version >= 5.7.9.

For Postgres you need server version >= 9.4.

Attention: Since v1.6.0 MariaDB Server has to be at least 10.2.11 due to a bugfix in MariaDB, see https://jira.mariadb.org/browse/MDEV-14402.

For MariaDB run the script in scripts/mariadb/01_event_streams_table.sql on your server.

For MySQL run the script in scripts/mysql/01_event_streams_table.sql on your server.

For Postgres run the script in scripts/postgres/01_event_streams_table.sql on your server.

This will setup the required event streams table.

If you want to use the projections, run additionally the scripts scripts/mariadb/02_projections_table.sql (for MariaDB), scripts/mysql/02_projections_table.sql (for MySQL) or scripts/postgres/02_projections_table.sql (for Postgres) on your server.

Starting from v1.7 the pdo-event-store uses optimized table schemas. The upgrade can be done in background with a script optimizing that process. A downtime for the database should not be needed. In order to upgrade your existing database, you have to execute:

• MariaDB

ALTER TABLE `event_streams` MODIFY `metadata` LONGTEXT NOT NULL;
ALTER TABLE `projections` MODIFY `position` LONGTEXT;
ALTER TABLE `projections` MODIFY `state` LONGTEXT;

Then for all event-streams (SELECT stream_name FROM event_streams)

ALTER TABLE <stream_name> MODIFY `payload` LONGTEXT NOT NULL;
ALTER TABLE <stream_name> MODIFY `metadata` LONGTEXT NOT NULL,

• MySQL

nothing to upgrade

• Postgres

For all event-streams (SELECT stream_name FROM event_streams)

ALTER TABLE <stream_name> MODIFY event_id UUID NOT NULL;

Additional note:

When using Postgres, the event_id has to be a valid uuid, so be careful when using a custom MetadataMatcher, as the event-store could throw an exception when passing a non-valid uuid (f.e. "foo") as uuid.

The migration is strongly recommended, but not required. It's fully backward-compatible. The change on Postgres is only a microoptimization, the change on MariaDB prevents errors, when the stored json gets too big.

If you want to run the unit tests locally you need a runnging MySql server listening on port 3306 and a running Postgres server listening on port 5432. Both should contain an empty database event_store_tests.
