Index question
Hi,
We doing POC for our system, based on kudu and have questions about indexing.
As far as I know we can define only one compound index.
We need the ability to define more than one index.
Is it on your roadmap? If so, when?
Btw, We using kudu over Cloudera.
Tnx,
Yariv

One more bit which might be relevant in this context: there is a
work-in-progress patch https://gerrit.cloudera.org/#/c/10983/ addressing
KUDU-1291. That's not secondary indices per se, but that might help in
some cases where the prefix component of the primary key is of low
cardinality.

Secondary indexing is a feature request that comes up fairly often.
KUDU-2613 is the tracking JIRA, but there's no real content in there.
Better to look at KUDU-2038, for which there's a work in progress
patch for bitmap indexing (https://gerrit.cloudera.org/c/11722/) that
you can also follow. It's hard to anticipate how quickly that patch is
moving or when it'll be merged.
