和memtable concurrent write一样，rocksdb的level 0到level 1的多线程compaction也是开始一个线程准备参数，然后开启多个线程并行执行，最终再由一个线程收尾的方式来提高并行度，一定程度上解决了level 0到level 1 compaction的瓶颈，代码算是梳理完了，不过rocksdb v5.0.1默认 ... RocksDB适合于多种不同工作量类型。 从像MyRocks这样的数据存储引擎， 到应用数据缓存, 甚至是一些嵌入式工作量，RocksDB都可以从容面对这些不同的数据工作量需求。 Yes, building a tool to guess a better default rocksdb configuration based on machine configuration is a good idea, but rocksdb configuration also depends on the workload. For instance, rocksdb configuration should focus on minimizing write amp in write heavy workload, while in read heavy workload it should minimize read amp.

Language Matters: C++, Java, or Go? RocksDB is written in C++ with the intent of exploiting the full throughput and low-latency of fast SSDs & non-volatile memory (NVM). For similar reasons, YugaByte DB is implemented in C++. We didn’t want to put an inter-language switch in the critical path of a database engine’s IO. Thanks for the feedback, Navina! Yes, as sdong9 mentioned, RocksDB Options are changeable on-the-fly by calling DB::SetOptions() in the RocksDB C++ API. However, this feature is currently missing in the RocksDB Java API. We will be adding this feature to the RocksDB Java API in the next six months.Since RocksDB 6.3, The unordered_write=true option together with WritePrepared transactions offers 34-42% higher write throughput compared to vanilla RocksDB. If the application can handle more relaxed ordering guarantees, the gain in throughput would increase to 63-131%. Background. Currently RocksDB API delivers the following powerful guarantees:
