I announce the first production release of pgreplay, version 1.0.0. Project home page: http://pgreplay.projects.postgresql.org/ pgreplay reads a PostgreSQL log file (*not* a WAL file), extracts the SQL statements and executes them in the same order and relative time against a PostgreSQL database cluster. If the execution of statements gets behind schedule, warning messages are issued that indicate that the server cannot handle the load in a timely fashion. The idea is to replay a real-world database workload as exactly as possible. pgreplay is useful for performance tests, particularly in the following situations: * You want to compare the performance of your PostgreSQL application on different hardware or different operating systems. * You want to upgrade your database and want to make sure that the new database version does not suffer from performance regressions that affect you. Features: * Should compile and run on any platform that PostgreSQL supports * Can replay the workload at different speeds * Can parse "stderr" and "csvlog" log files * Can save workload to replay in "replay file" for reuse * Outputs detailed parse and execution statistics Enjoy! Yours, Laurenz Albe
