| Description |
|
We are not supporting multi-document write transactions for time-series collections. There appear to be some liveness issues that need to be addressed. Notably, writers wait for their bucket to commit, and may do this while holding open a long-running transaction. This appears to also interact poorly with TTL monitor, preventing it from deleting expired buckets. |

We should consider tagging the existing time-series tests in jstests/core/timeseries with the new does_not_support_transactions tag introduced in |
