> WASB: Block compaction for Azure Block Blobs
> --------------------------------------------
>
> Key: HADOOP-14520
> URL: https://issues.apache.org/jira/browse/HADOOP-14520
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/azure
> Affects Versions: 3.0.0-alpha3
> Reporter: Georgi Chalakov
> Assignee: Georgi Chalakov
> Attachments: HADOOP-14520-01.patch, HADOOP-14520-01-test.txt,
> HADOOP-14520-03.patch, HADOOP-14520-4.patch
>
>
> Block Compaction for WASB allows uploading new blocks for every hflush/hsync
> call. 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. Similar to the configuration for
> page blobs, the client needs to specify HDFS folders where block compaction
> over block blobs is enabled.
> Results for HADOOP-14520-04.patch
> tested endpoint: fs.azure.account.key.hdfs4.blob.core.windows.net
> Tests run: 701, Failures: 0, Errors: 0, Skipped: 119
