---------------------------------
Resolution: Fixed
> 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
> Priority: Major
>
> 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.
