> Use DateTieredCompactor for Date Tiered Compaction
> --------------------------------------------------
>
> Key: HBASE-15400
> URL: https://issues.apache.org/jira/browse/HBASE-15400
> Project: HBase
> Issue Type: Sub-task
> Components: Compaction
> Reporter: Clara Xiong
> Assignee: Clara Xiong
> Fix For: 2.0.0
>
> Attachments: HBASE-15400-15389-v12.patch, HBASE-15400-v1.pa,

> When we compact, we can output multiple files along the current window
> boundaries. There are two use cases:
> 1. Major compaction: We want to output date tiered store files with data
> older than max age archived in trunks of the window size on the higher tier.
> Once a window is old enough, we don't combine the windows to promote to the
> next tier any further. So files in these windows retain the same timespan as
> they were minor-compacted last time, which is the window size of the highest
> tier. Major compaction will touch these files and we want to maintain the
> same layout. This way, TTL and archiving will be simpler and more efficient.
> 2. Bulk load files and the old file generated by major compaction before
> upgrading to DTCP.
> Pros:
> 1. Restore locality, process versioning, updates and deletes while
> maintaining the tiered layout.
> 2. The best way to fix a skewed layout.
>
> This work is based on a prototype of DateTieredCompactor from HBASE-15389 and
> focused on the part to meet needs for these two use cases while supporting
> others. I have to call out a few design decisions:
> 1. We only want to output the files along all windows for major compaction.
> And we want to output multiple files older than max age in the trunks of the
> maximum tier window size determined by base window size, windows per tier and
> max age.
> 2. For minor compaction, we don't want to output too many files, which will
> remain around because of current restriction of contiguous compaction by seq
> id. I will only output two files if all the files in the windows are being
> combined, one for the data within window and the other for the out-of-window
> tail. If there is any file in the window excluded from compaction, only one
> file will be output from compaction. When the windows are promoted, the
> situation of out of order data will gradually improve. For the incoming
> window, we need to accommodate the case with user-specified future data.
> 3. We have to pass the boundaries with the list of store file as a complete
> time snapshot instead of two separate calls because window layout is
> determined by the time the computation is called. So we will need new type of
> compaction request.
> 4. Since we will assign the same seq id for all output files, we need to sort
> by maxTimestamp subsequently. Right now all compaction policy gets the files
> sorted for StoreFileManager which sorts by seq id and other criteria. I will
> use this order for DTCP only, to avoid impacting other compaction policies.
> 5. We need some cleanup of current design of StoreEngine and CompactionPolicy.
