Riemann 0.1.0 Released as First Stable Build
The initial stable release of Riemann 0.1.0 is now available. The release follows the 0.0.3 development path and has been running in production at Showyou for two months.
According to the author, the fundamentals are solid: core stream operators are complete, a comprehensive test suite passes, and the daemon has not crashed in production. Its performance profile should fit a broad range of scales and applications.
One known caveat: a possible memory leak on the order of 1% per day in the production setup remains unresolved. The leak cannot be reproduced under stress testing, and it is unclear whether it stems from legitimate growth in tracked state, greedy garbage collection or malloc behavior, or an actual bug. Profiling is the top priority for the project going forward. For users who hit the issue, restarting the daemon takes roughly five seconds and is recommended every few weeks; those who encounter it should report their configuration to help isolate the cause.
The scheduled Riemann talk at Boundary tonight is sold out, with a possible repeat event in the coming month.
