Change subject: [ASTERIXDB-2186][STO] Cache-friendly Bloom Filter
......................................................................
[ASTERIXDB-2186][STO] Cache-friendly Bloom Filter
- user model changes: no
- storage format changes: yes. Change the format of bloom filter
- interface changes: no
Details:
- Introduce blocked bloom filter to guarantee only 1 random memory
access is required during each membership check. It improves bloom
filter performance by 2x - 4x, depending on the ratio of positive
queries.
- For legacy bloom filters, we fall back to previous implementation
based on the stored version in the metadata.
- Add pinAllPages/unpinAllPages method to reduce pin/unpin overhead.
