Yep, I've been taking part in those design discussions. We hope to have Kudu tablet servers support generating this in-memory format in shared memory as the result of scans, so the Impala server (client from Kudu's perspective) can directly operate on the data. We're expecting a 20-30% speed boost from this for some queries, though haven't done any tests at scale of the prototype. |
