> 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.
