Summary: Before running CompactFilesTest.SentinelCompressionType, we should check whether zlib and snappy are supported. CompactFilesTest.SentinelCompressionType is a newly added test. Compilation and linking with different options, e.g. COMPILE_WITH_TSAN, COMPILE_WITH_ASAN, etc. lead to generation of different binaries. On the one hand, it's not clear why zlib or snappy is present under ASAN, but not under TSAN. On the other hand, changing the compilation flags for TSAN or ASAN seems a bigger change worth much more attention. To unblock the cont-runs, I suggest that we simply add these two checks at the beginning of the test, as we did for GeneralTableTest.ApproximateOffsetOfCompressed in table/table_test.cc. Future actions include invesigating the absence of zlib and snappy when compiling with TSAN, i.e. COMPILE_WITH_TSAN=1, if necessary.

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.
