Subject [jira] [Created] (HBASE-17327) Allow for lazy connection / BufferedMutator creation
Date Fri, 16 Dec 2016 22:18:59 GMT
Joep Rottinghuis created HBASE-17327:

             Summary: Allow for lazy connection / BufferedMutator creation
                 Key: HBASE-17327
                 URL: https://issues.apache.org/jira/browse/HBASE-17327
             Project: HBase
          Issue Type: Sub-task
            Reporter: Joep Rottinghuis

The SpoolingBufferedMutatorImpl solution (HBASE-17018) solved the use-case when an existing
HBase connection stalls out due to HBase being down, or other transient issues.

We have a remaining issue that our service will not start up if it cannot initially connect
to HBase.
This can be solved by letting the SpoolingBufferedMutator create the wrapped BufferedMutatorImpl
later, but the problem has already occurred: we already have to have a connection in order
to create a BufferedMutator to begin with.

It would be good to be able to initiate a connection and then have a way for multiple users
to wait for the connection to succeed before using it.
I'm thinking perhaps create a LazyConnection interface that extends the Connection interface.
It would have an additional waitFor(long timeout, TimeUnit unit) method where clients can
wait for the connection to be established before they start using the connection.
Or perhaps the ConnectionFactory can have a createLazyConnection method.
