Summary: (1)Make CompactionService derived from Customizable by defining two extra functions that are needed, as described in customizable.h comment section (2)Revise the MyTestCompactionService class in compaction_service_test.cc to satisfy the class inheritance requirement (3)Specify namespace of ToString() in compaction_service_test.cc to avoid function collision with CompactionService's ancestor classes Test did: make -j24 compaction_service_test ./compaction_service_test Pull Request resolved: https://github.com/facebook/rocksdb/pull/8395 Reviewed By: jay-zhuang Differential Revision: D29076068 Pulled By: hx235 fbshipit-source-id: c130100fa466939b3137e917f5fdc4b2ae8e37d4
RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
