| 7 | RocksDB is developed and maintained by Facebook Database Engineering Team. | |
| 8 | It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) | |
| 9 | and Jeff Dean (jeff@google.com) | |
| 10 | ||
| 11 | This code is a library that forms the core building block for a fast | |
| 12 | key value server, especially suited for storing data on flash drives. | |
| 13 | It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs | |
| 14 | between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) | |
| 15 | and Space-Amplification-Factor (SAF). It has multi-threaded compactions, | |
| 16 | making it specially suitable for storing multiple terabytes of data in a | |
| 17 | single database. | |

| 23 | The public interface is in `include/`. Callers should not include or | |
| 24 | rely on the details of any other header files in this package. Those | |
| 25 | internal APIs may be changed without warning. | |
