Method Detail

recover

public void recover(OffsetContext offset)

Specified by:

recover in interface HistorizedDatabaseSchema<TableId>

close

public void close()

Specified by:

close in interface DatabaseSchema<TableId>

Overrides:

close in class RelationalDatabaseSchema

getDdlParser

protected abstract DdlParser getDdlParser()

Returns a new instance of the DdlParser to be used when recovering the schema from a previously persisted history.

record

protected void record(SchemaChangeEvent schemaChange,
                      TableChanges tableChanges)

Records the given schema change event in the persistent history.
