Subject [jira] [Commented] (HBASE-6942) Endpoint implementation for bulk delete rows
Date Sat, 20 Oct 2012 15:04:12 GMT

Anoop Sam John commented on HBASE-6942:
---------------------------------------

bq.For passing the delete type bytes. What I meant was to use a enum backed by bytes
Lars we can not make the signature of endpoint like delete(Scan, DeleteType..)
I also tried initially like enum backed with byte.. But any way when customer calls the endpoint
as delete(Scan, deleteType.getBytes()... )
I thought that will be only confusion..:(
We are not supporting enum type as a parameter to Endpoint

> We can provide an end point implementation for doing a bulk deletion of rows(based on
a scan) at the server side. This can reduce the time taken for such an operation as right
now it need to do a scan to client and issue delete(s) using rowkeys.
