findReplicaIdentity

public Optional<ReplicaIdentityInfo> findReplicaIdentity(TableId tableId)
                                                  throws DebeziumException

This method get the Replica Identity of the TableId, checking if the TableId is contained in the Map of Predicates stored in replicaIdentityPredicateMap

Parameters:

tableId - the identifier of the table

Returns:

ReplicaIdentityInfo of the TableId

Throws:

DebeziumException - if there is a problem obtaining the replica identity for the given table

getReplicaIdentityPredicateMap

private Map<Predicate<TableId>,ReplicaIdentityInfo> getReplicaIdentityPredicateMap()

This method parses the property `replica.identity.autoset.values` stored in replicaAutoSetValue attribute generating a map collection with the Table and its respective Replica Identity

Returns:

Map collection that contains TableId as Key and ReplicaIdentityInfo as value
