Hive on Accumulo recommended settings -

-

we use hive (v. 1.2.1) read "sql like" on accumulo (v. 1.7.1) tables.

is there special settings can configure in hive or somewhere gain our performance or stability?

if use hive way there point example trying out hive indexing or whatever settings "hive.auto.convert.join" or works different way , not affect in these case?

thank you!

obligatory: wrote (most of) accumulostoragehandler, no means hive expert.

the biggest gain able find when can structure query in such way can either prune row-space (via statement in clause on :rowid-mapped column). knowledge, there isn't (any?) query optimization pushed down accumulo itself.

depending on workload, use hive generate own "index tables" in accumulo. if can make custom table has column want actively query stored in accumulo row, queries should run faster.
