MongoDB uses a configuration file to specify different options for the instance to configure during startup. The location of this file can be found at the following locations in each operating system :
- Microsoft Windows - C:\Program Files\MongoDB\Server\5.0\bin/mongod.cfg
- Linux - /etc/mongod.conf
For MongoDB on FlashArray volumes it is recommended to turn off all compression options for the journal, indexes and collections. To turn off compression ensure that the following entries are added for the wiredTiger entries (under storage) of the configuration file :
# Where and how to store data.
storage:
dbPath: /var/lib/mongo
journal:
enabled: true
wiredTiger:
engineConfig:
journalCompressor: none
indexConfig:
prefixCompression: false
collectionConfig:
blockCompressor: none
