Flush Dirty bytes

[Kushagra_Kesav]

Hi @Prince_Das,

@Prince_Das

thought Mongodb might be having similar type of feature where we can flush those dirty bytes.

but not in regularly , Only if it reaches near to “bytes currently in the cache” . We can us those command …For temp. purpose.

In MongoDB, you don’t need to manually flush dirty bytes. The system takes care of automatically flushing them to disk once dirty contents in the WiredTiger cache reach 5%. It will flush them more aggressively once this number reaches 20% of the configured cache size. You can customize these numbers if you need more control, but unless you’re experiencing issues that can be conclusively traced to this setting, I would not recommend changing these values.

To read more, please refer to the WiredTiger: Cache and eviction tuning documentation.
