Open Projects

• Pluggable WAL
• Data encryption
• Warm block cache after flush and compactions in a smart way
• Eliminate restriction of AddFile()
• Queryable Backup
• Tools to collect operations to a database and replay them
• Customized bloom filter for data blocks
• Native support of range delete
• Build a new compaction style optimized for time series data
• Benchmark FIFOCompaction
• Implement YCSB benchmark scenarios in db_bench
• Improve DB recovery speed when WAL files are large (parallel replay WAL)
• Column-Aware Block Compression for MySQL+RocksDB
• use thread pools to do readahead + decompress and compress + write-behind. Igor started on this. When manual compaction is multi-threaded then we can use RocksDB as a fast external sorter -- load keys in random order with compaction disabled, then do manual compaction.
• expose merge operator in MongoDB + RocksDB
• SQLite + RocksDB
• Snappy compression for WAL writes. Maybe this is only done for large writes and maybe we add a field to WriteOptions so a user can request it.
• Improve performance of statistics by making use of thread local storage
