Feature
What is this PR about? / Why do we need it?
Coalesces EC2 DescribeSnapshots calls across CreateSnapshot/DeleteSnapshot/ListSnapshots RPCs by Snapshot ID or by tag.
This decreases the likelihood of being exceeding one's Non-mutating API request token limit when creating many snapshots at once, which may impact all driver RPCs (ie being throttled for making too many
Describe*calls).What testing is done?
Manual testing on modified Volume Snapshots example to check that calls were batched.
TODO manual testing on ListSnapshots RPC.
possible snapshot scalability test. We would tune snapshot batcherOffline decided to start with conservative maxDelay, and tune once snapshot scalability tests are prioritized.maxDelays based on these tests.CI
