How to check and decrease DocumentDB IOPS

Hello alihaider,

1. Check/Monitor IOPS:

• Go to Amazon CloudWatch.
• View metrics associated with your DocumentDB cluster. Specifically, look at the ReadIOPS and WriteIOPS metrics to understand your current IOPS usage.

2. Reduce IOPS practices:

• Optimize Queries and Indexes: Ensure that your queries are efficient and your indexes are optimized for the most frequently executed queries.
• Data Cleanup: Periodically review your data and consider archiving or deleting old or infrequently accessed data. Fewer data usually means less IOPS for read and write operations.
• Use Caching: Implement caching mechanisms like Amazon ElastiCache to offload frequent read operations from DocumentDB, thereby reducing IOPS.

By following these steps, you can have a clearer insight into your IOPS usage and take actions to reduce it.
