Keith Turner commented on ACCUMULO-3134:
----------------------------------------

bq. Since we can't predict what options everybody's custom compaction strategies will need, does it make sense to just accept a map for configuration?

My thinking was that these options would leverage a specific compaction strategy built into accumulo.  If the compact command had an option for specifying a general compaction strategy w/ option map, then that could be mutually exclusive w/ these options.  I think this approach will be less cumbersome to use, while still allowing generalization thats more cumbersome.

> Using a specialized compaction strategy and ACCUMULO-1798, options could be added to the shell's compact command to select specific files and configure the output file.   
> For example options like the following could be added for file selection.
>  * --sf-lt-size : select files less than a configurable size
>  * --sf-volume : selects files with a specified volume
>  * --sf-volume-re : selects files where the volume matches the specified regex
>  * --sf-name : selects files with a specfied name
>  * --sf-name-re : selects files where the name matches the specified regex
>  * --sf-compression : selects files with the specified compression type
>  * --sf-hdfs-block-size : selects files with a given hdfs block size
>  * --sf-rfile-data-block-size : selects file with a given rfile data block size
>  * --sf-rfile-index-block-size : selects file with a given rfile index block size
> Options like the following could be added for file creation.
>  * --out-compression : creates a file with the specified compression type
>  * --out-hdfs-block-size : creates a file with a given hdfs block size
>  * --out-rfile-data-block-size : creates a file with a given rfile data block size
>  * --out-rfile-index-block-size : creates a file with a given rfile index block size
