@InterfaceAudience.LimitedPrivate(value="Replication") public interface WALEntryFilter
ChainWALEntryFilter. Applied on the replication source side.
There is also a filter that can be installed on the sink end of a replication stream. See
WALEntrySinkFilter. Certain use-cases
may need such a facility but better to filter here on the source side rather than later, after
the edit arrives at the sink.
|Modifier and Type||Method and Description|
Applies the filter, possibly returning a different Entry instance.
WAL.Entry filter(WAL.Entry entry)
Applies the filter, possibly returning a different Entry instance. If null is returned, the entry will be skipped.
Notice that you are free to modify the cell list of the give entry, but do not change the content of the cell, it may be used by others at the same time(and usually you can not modify a cell unless you cast it to the implementation class, which is not a good idea).
