Igniters, I've recently stumbled across a situation when occasionally Ignite transactions commit may take up to several seconds while in general most of the transactions completed in a period of milliseconds.
After a few attempts to analyze this situation with logs, I realized that this is a no-go and I need a finer instrument for this. The idea is to introduce several trace points along the way of an Ignite operation and collect timings when an operation passes each of the trace points. When enabled, this information should be available upon the operation completion. I've implemented a prototype of this for TX commit operation, the implementation is available in ignite-5797 branch. I was wondering if something of this kind may be useful as a part of Ignite product and available to users. If so, I would like to discuss the public API for this so the feature can be finalized. Thanks, AG
