The existing logic for inserting measurements into time-series collections does not consider retryable writes that may result in a no-op in write_ops::performUpdates. This may throw off the bucket catalog's accounting for the element count in the data field.
==== OLD DESCRIPTION ====
Time-series tests are currently excluded from the retryable writes jscore passthrough suites using the does_not_support_causal_consistency test tag. It would be beneficial for test coverage to look into whether this restriction can be lifted.
