Summary: Thanks to https://github.com/facebook/rocksdb/issues/9919 and https://github.com/facebook/rocksdb/issues/10051 the known bugs in file ingestion (besides mmap read + file checksum) are fixed. Now we can try again to enable file ingestion in crash test. Pull Request resolved: https://github.com/facebook/rocksdb/pull/9357 Test Plan: stress file ingestion heavily for an hour: `$ TEST_TMPDIR=/dev/shm python3 tools/db_crashtest.py blackbox --max_key=1000000 --ingest_external_file_one_in=100 --duration=3600 --interval=20 --write_buffer_size=524288 --target_file_size_base=524288 --max_bytes_for_level_base=2097152` Reviewed By: riversand963 Differential Revision: D33410746 Pulled By: ajkr fbshipit-source-id: d276431390995a67f68390d61c06a40945fdd280 |

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.
Start with example usage here: https://github.com/facebook/rocksdb/tree/main/examples
See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
