Summary: When atomic flush stress test fails, we print internal keys within the range with mismatched key/values for all column families. Test plan (on devserver) Manually hack the code to randomly insert wrong data. Run the test. ``` $make clean && COMPILE_WITH_TSAN=1 make -j32 db_stress $./db_stress -test_atomic_flush=true -ops_per_thread=10000 ``` Check that proper error messages are printed, as follows: ``` 2019/07/08-17:40:14 Starting verification Verification failed Latest Sequence Number: 190903 [default] 000000000000050B => 56290000525350515E5F5C5D5A5B5859 [3] 0000000000000533 => EE100000EAEBE8E9E6E7E4E5E2E3E0E1FEFFFCFDFAFBF8F9 Internal keys in CF 'default', [000000000000050B, 0000000000000533] (max 8) key 000000000000050B seq 139920 type 1 key 0000000000000533 seq 0 type 1 Internal keys in CF '3', [000000000000050B, 0000000000000533] (max 8) key 0000000000000533 seq 0 type 1 ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/5549 Differential Revision: D16158709 Pulled By: riversand963 fbshipit-source-id: f07fa87763f87b3bd908da03c956709c6456bcab |

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 specially suitable for storing multiple terabytes of data in a single database.
Start with example usage here: https://github.com/facebook/rocksdb/tree/master/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.
Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
