- def currentPersistenceIds(entityType: String, afterId: Option[String], limit: Long): Source[String, NotUsed]
Get the current persistence ids.
Get the current persistence ids.
Note: to reuse existing index, the actual query filters entity types based on persistence_id column and sql LIKE operator. Hence the persistenceId must start with an entity type followed by default separator ("|") from akka.persistence.typed.PersistenceId.
- entityType
The entity type name.
- afterId
The ID to start returning results from, or None to return all ids. This should be an id returned from a previous invocation of this command. Callers should not assume that ids are returned in sorted order.
- limit
The maximum results to return. Use Long.MaxValue to return all results. Must be greater than zero.
- returns
A source containing all the persistence ids, limited as specified.
- def currentPersistenceIds(afterId: Option[String], limit: Long): Source[String, NotUsed]
Note: If you have configured
custom-table
this query will look in both the default table and the custom tables.Note: If you have configured
custom-table
this query will look in both the default table and the custom tables. If you are only interested in ids for a specific entity type it's more efficient to usecurrentPersistenceIds

if the existing storedrevision

.Delete the value, which will fail with
IllegalStateException
if the existing storedrevision
+ 1 isn't equal to the givenrevision
. This optimistic locking check can be disabled with configurationassert-single-writer
. The stored revision for the persistenceId is updated and next call to getObject will return the revision, but with no value.If the given revision is
0
it will fully delete the value and revision from the database without any optimistic locking check. Next call to getObject will then return revision 0 and no value.The
changeEvent
is written to the event journal in the same transaction as the DurableState upsert. SamepersistenceId
is used in the journal and therevision
is used assequenceNr
