What’s the use case for re-checking the same feature flag in a single session?
I can see why you need to check multiple different flags in a session and I understand the parent point about looking in SQLite for them (effectively a function call into a library in process address space rather than a call over the network for each flag).
- quesera 2y agoSorry, s/session/request/g; corrected above. One example is a multistep transaction processing request. The feature flag could gate several branch points. A memory-mapped SQLite file is great too, but the strategy I describe above is less code to write, adds no new dependencies, is quicker to implement, avoids the SQLite file distribution/availability issues, and should get you a very similar performance improvement.
