> ChainWalEntryFilter applies the filter on entry followed by filter on cells.
> If filter on cells remove all the cells from the entry, we should add an option in chainwalentryfilter to filter the entry as well.
> Here is the snippet for ChainWalEntryFilter filter. After filterCells we should check if there is any cells remaining in the entry.
> {code:java}
> @Override
> public Entry filter(Entry entry) {
> for (WALEntryFilter filter : filters) {
> if (entry == null) {
> return null;
> }
> entry = filter.filter(entry);
> }
> filterCells(entry);
> return entry;
> }{code}
> Customer replication endpoints may use this flag.
