Summary: Having all of TMPD, TMPDIR and TEST_TMPDIR as configuration parameters is confusing. This change simplifies a number of things by standardizing on TEST_TMPDIR, while still recognizing the old names also. In detail: * crash_test.mk also needs to use TEST_TMPDIR for crash test, so put in shared common.mk (an upgrade of python.mk) * Always exporting TEST_TMPDIR eliminates the need to propagate TMPD or export TEST_TMPDIR in selective places. * Use --tmpdir option to gnu_parallel so that it doesn't need TMPDIR environment variable * Remove obsolete parloop and parallel_check Makefile targets * Remove undefined, unused function ResetTmpDirForDirectIO() Pull Request resolved: https://github.com/facebook/rocksdb/pull/9961 Test Plan: manual + CI Reviewed By: riversand963 Differential Revision: D36212178 Pulled By: pdillinger fbshipit-source-id: b76c1876c4f4d38b37789c2779eaa7c3026824dd
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.
