Support selective caching of index files only during compaction in cloud
mode.
Changes:
- Add two mBool configs to control index-only caching for base and
cumulative compaction:
* enable_base_compaction_output_write_index_only (default: false)
* enable_cumu_compaction_output_write_index_only (default: false)
- Extend RowsetWriterContext with compaction_output_write_index_only field
to mark whether only index files should be cached
- Modify get_file_writer_options() to accept is_index_file parameter:
* When compaction_output_write_index_only=true and is_index_file=false,
set write_file_cache=false to skip caching data files
* Index files continue to be cached normally
- Update file writer creation call sites to pass is_index_file parameter:
* Index file writers: pass true
* Segment (data) file writers: pass false
Benefits:
- Reduces cache pressure by avoiding caching large data files during
compaction
- Preserves index file caching for query performance
- Provides separate control for base and cumulative compaction strategies
- Maintains backward compatibility with default settings
