Akanksha Mahajan cd79a00903 Make BlockBasedTable::kMaxAutoReadAheadSize configurable (#7951) ... Summary: RocksDB does auto-readahead for iterators on noticing more than two reads for a table file. The readahead starts at 8KB and doubles on every additional read upto BlockBasedTable::kMaxAutoReadAheadSize which is 256*1024. This PR adds a new option BlockBasedTableOptions::max_auto_readahead_size which replaces BlockBasedTable::kMaxAutoReadAheadSize and the new option can be configured. If max_auto_readahead_size is set 0 then no implicit auto prefetching will be done. If max_auto_readahead_size provided is less than 8KB (which is initial readahead size used by rocksdb in case of auto-readahead), readahead size will remain same as max_auto_readahead_size.
