| Description |
|
This bug is similar to In the concurrency suite, the drop_database.js FSM workload repeatedly creates and drops collections. With mmapv1, these sequences lead to the writing of ~12GB worth of cumulative data during the workload's lifetime, when run against a replica set. We should reduce the amount of data written to disk to speed up the workload and to prevent failures on Evergreen hosts. |
