Description
ORIGINAL TITLE: View compaction doesn't catch up in basic non-DGM tests with view queries
4 nodes, 1 bucket x 20M x 2KB, non-DGM, 4 ddocs, 1 view per ddoc.
10K op/sec (read-heavy), 400 queries/sec.
Data and index are on different SSD drives, parallel compaction is enabled.
See attached screenshot that compares index fragmentation between 2.5 and 3.0.
I observe similar issue with data compaction where way higher drain rate causes IO saturation. However in this case:
1. Isolated index compaction is known to be faster.
2. There is enough CPU and disk bandwidth.
