Error Injection Pr

Goals:

• find the minimum set of shard assignments that must have resilient behavior for shard assignments callsites to work end to end.
• guard against regressions for CRUD requests that are known to work correctly given current resiliency protocols.
• Make slight augmentations to our resiliency job to allow verifying resiliency for only a subset of all MySQL main queries.

TODOs:

• figure out how to make the shard assignments runner a variant of the existing runner.

PR chain -> live shard helper refactoring — withCompositeConnectionAsMainConnectionAsync becoming object, and scanShardsForObjectAsync having a callsite -> resiliency runner with:

1. new queryHashesToForceInject field
2. New beforeEach and afterEach, where we’re doing only shard assignments setup
3. New crud requests that will run in all environments — do this first, make sure that existing tests work.
4. Uncomment out the “only some processes tests”
5. Add comments about the weirdness for certain things — Need to add a new crud request end-point for helper

Things to talk about with Keunwoo –
