Oban.Peers.Database (Oban v2.19.1)
View SourceA peer that coordinates centrally through a database table.
Database peers don't require clustering through distributed Erlang or any other
interconnectivity between nodes. Leadership is coordinated through the oban_peers
table in
your database. With a standard Oban config the oban_peers
table will only have one row, and
that node is the leader.
Applications that run multiple Oban instances will have one row per instance. For example, an
umbrella application that runs Oban.A
and Oban.B
will have two rows in oban_peers
.
Usage
This is the default peer for the Basic
and Dolphin
engines and no configuration is
necessary. However, to be explicit, specify the Database
peer in your configuration.
