Description

As https://issues.apache.org/jira/browse/HBASE-6942 introduced, BulkDeleteEndpoint provides 'delete' method which performs like sql : "delete from table where ...". BulkDeleteEndpoint is efficient because it can complete scan and delete in one rpc and also could be implemented parallelly in different regions using coprocessor. BulkDeleteResponse is represents the result of BulkDeleteEndpoint.delete and will be serialized using a standard java serializable way. However, the serialized length of BulkDeleteResponse will be longer than one hundred byte length and may be not efficient enough to pass on the network. Therefore, is it better to make BulkDeleteResponse implement Writable interface and provide more efficient serialize method?
