This blog post highlights a group of improvements that were released with OneAgent version 1.199. Storage mount points in a system might be larger or smaller, local or remote, with high or low latency, and various speeds. Storage and network transfer of files is a measurable cost. See details below. See details below.

Compression in any database is necessary as it has many advantages, like storage reduction, data transmission time, etc. Storage reduction alone results in significant cost savings, and we can save more data in the same space. In this blog, we will discuss both data and network-level compression offered in MongoDB.

A Dedicated Log Volume (DLV) is a specialized storage volume designed to house database transaction logs separately from the volume containing the database tables. DLVs are particularly advantageous for databases with large allocated storage, high I/O per second (IOPS) requirements, or latency-sensitive workloads.
