[jira] [Updated] (HADOOP-14520) Block compaction for WASB (Block Blobs Instead of Page Plobs)
[ https://issues.apache.org/jira/browse/HADOOP-14520?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Georgi Chalakov updated HADOOP-14520: - Release Note: Block Compaction for WASB. When the number of blocks in a block blob is above 32000, the process of compaction replaces a sequence of small blocks with with one big block. (was: Block Compaction for WASB. When the number of blocks in a block blob is above 32000, compaction replaces longest sequence of blocks with total size length less then 4M, with just one block. Compaction allows blocks blobs to be used instead of page blobs, including for WAL files.)

When the number of blocks is above 32000, next hflush/hsync triggers the block compaction process. Block compaction replaces a sequence of blocks with one block. From all the sequences with total length less than 4M, compaction chooses the longest one. It is a greedy algorithm that preserve all potential candidates for the next round. Block Compaction for WASB increases data durability and allows using block blobs instead of page blobs. By default, block compaction is disabled.
