def migratePidsToTagViews(pids: Seq[PersistenceId], periodicFlush: Int = 1000, flushTimeout: Timeout = Timeout(30.seconds)): Future[Done]

Migrates the given persistenceIds from the messages table to the new tags_view table.
Migrates the given persistenceIds from the messages table to the new tags_view table. tag_view table must exist before calling this and can be created manually or via [createTagsTable]
This is useful if there there is a more efficient way of getting all the persistenceIds than [CassandraReadJournal.currentPersistenceIds] which does a distinct query on the messages table.
This can also be used to do partial migrations e.g. test a persistenceId in production before migrating everything.
It is recommended you use this if the messages table is large.
pids
PersistenceIds to migrate
returns
A Future that completes when the migration is complete
def migrateToTagViews(periodicFlush: Int = 1000, filter: (String) ⇒ Boolean = _ => true, flushTimeout: Timeout = Timeout(30.seconds)): Future[Done]

Migrates the entire messages table to the the new tag_views table.
Migrates the entire messages table to the the new tag_views table.
Uses [CassandraReadJournal.currentPersistenceIds] to find all persistenceIds. Note that this is a very inefficient cassandra query so might timeout. If so the version of this method can be used where the persistenceIds are provided.
Persistence ids can be excluded (e.g. useful if you know certain persistenceIds don't use tags
returns
A Future that completes when the migration is complete.
