It uses native > HBase client to insert the mutations. Sometime, it takes a while to process > it (may be due to region splitting, gc pause, etc) and it undergoes the > retrial phase. > It has two repercussions: > a) The regionserver handler which is serving the request (till now, a > priority handler) is blocked for this period. > b) The caller may get timed out and it will retry it anyway, but the handler > serving the ReplicationSink requests is still working. > Refactoring ReplicationSink to have the following features: > a) Making it more configurable (have its own number of retrial limit, > connection timeout, etc) > b) Add a fail fast behavior so that it bails out in case caller is timedout, > or any exception in processing the mutation batch. -- This message is automatically generated by JIRA.
