| Description |
|
In the concurrency suite, the rename_collection_dbname_chain.js FSM workload repeatedly renames collections across databases. With mmapv1, these renames lead to the writing of > 15GB worth of cumulative data during the workload's lifetime. We should reduce the amount of data written to disk to speed up the workload and to prevent failures on Evergreen hosts. |
