[TRAFODION-9] Non-blocking hbase operation to smoothen the data flow â¦
â¦in trafodion engine
The non-blocking Hbase operation for the index maintenance operators is now
enabled by
default for IUD, merge and update commands.
The Hbase operations put, checkAndPut and delete operations from the
trafodion engine
for the index maintenance is done using Executor Services to make it
non-blocking and the
data flow in the trafodion operators can continue up to the point till it
needs to pause for completion.
checkAndDelete is never used for index maintenance now.
Also, ensured that index maintenance uses rowset or single row operators
when it should.
