Summary: - If block cache disabled or not used for meta-blocks, `BlockBasedTableReader::Rep::uncompression_dict` owns the `UncompressionDict`. It is preloaded during `PrefetchIndexAndFilterBlocks`. - If block cache is enabled and used for meta-blocks, block cache owns the `UncompressionDict`, which holds dictionary and digested dictionary when needed. It is never prefetched though there is a TODO for this in the code. The cache key is simply the compression dictionary block handle. - New stats for compression dictionary accesses in block cache: "BLOCK_CACHE_COMPRESSION_DICT_*" and "compression_dict_block_read_count" Pull Request resolved: https://github.com/facebook/rocksdb/pull/4881 Differential Revision: D13663801 Pulled By: ajkr fbshipit-source-id: bdcc54044e180855cdcc57639b493b0e016c9a3f |
