Troubleshoot I/O & Wait Latency with OraLatencyMap and PyLatencyMap
Troubleshoot I/O & Wait Latency with OraLatencyMap and PyLatencyMap I recently chased an Oracle performance issue where most reads were sub-millisecond (cache), but a thin band around ~10 ms (spindles) dominated total wait time. Classic bimodal latency: the fast band looked fine in averages, yet the rare slow band owned the delay. To investigate, and

Testing a Small Query Language in Python with Hypothesis
Testing a Small Query Language in Python with Hypothesis Hypothesis is an implementation of Property-based testing for Python, similar to QuickCheck in Haskell/Erlang and test.check in Clojure (among others). Basically, it allows the programmer to formulate invariants about their programs, and have an automated system attempt to generate counter-examples that invalidates them. A Small Query
