Description
Setup:
- 4 KV nodes, 1 query node, 1 index node
- 1 bucket
- 100M documents (non-DGM)
- 30K updates/sec
Index:
CREATE INDEX by_capped_small ON `bucket-1`(capped_small);
|
Queries:
SELECT COUNT(*) FROM `bucket-1` WHERE capped_small > $1 AND capped_small < $2;
|
Those queries match ether 1K or 10K documents. Both cases regressed. Both MOI and Plasma are affected.
