> Block Encoding Size Estimation
> ------------------------------

> Key: HBASE-6597
> URL: https://issues.apache.org/jira/browse/HBASE-6597
> Project: HBase
> Issue Type: Improvement
> Components: io

> Blocks boundaries as created by current writers are determined by the size of
> the unencoded data. However, blocks in memory are kept encoded. By using an
> estimate for the encoded size of the block, we can get greater consistency in
> size.
