It improves performance, but users need to set file descriptor limit to be large enough and watch memory usage for index and bloom filters. * options.base_background_compactions changes from max_background_compactions to 1. When users set higher max_background_compactions but the write throughput is not high, the writes are less spiky to disks. * options.wal_recovery_mode changes from kTolerateCorruptedTailRecords to kPointInTimeRecovery. Avoid some false positive when file system or hardware reorder the writes for file data and metadata. -# RocksDB default options change log ## 4.7.0 (4/8/2016) * options.write_buffer_size changes from 4MB to 64MB. * options.target_file_size_base changes from 2MB to 64MB. |
