-----------------------------------
Summary: Bloomfilter size is overly calculated for update-heavy
workloads
Key: ASTERIXDB-2243
URL: https://issues.apache.org/jira/browse/ASTERIXDB-2243
Project: Apache AsterixDB
Issue Type: Bug
Components: STO - Storage
Reporter: Chen Luo
Assignee: Chen Luo
The current bloom filter calculation assumes the data is append-only without
updates. Each bloom filter maintains the number of elements. When bulkload a
new bloom filter through merge, the new size is simply the sum of all sizes.
However, in a update-heavy workloads, even though the actual size of the merged
disk component does not increase, the estimated bloom filter size will keep
increasing and consume too much space.
