| Description |
|
The WiredTiger engine automatically closes and evicts idle tables in order to free cache space quickly. There are three knobs that can be adjusted to tune when and how often the file manager checks for idle tables.
The defaults should be increased in the MongoDB integration layer. This will result in the regular LRU eviction policy to control when collections are evicted from cache and is more in line with behavior most users expect. |
