Some time ago, we decided to take a stab at a number of architectural challenges present in the OneAgent installer for Windows. Consequently, each new version of OneAgent for Windows consumed double storage space: one for the *.exe exe files is available with OneAgent version 1.167 and Dynatrace SaaS version 1.168. msi artifact.

Not only that, the idea is to present you with changes flying under the radar, which, in my understanding, can influence your daily operation.

At this scale, we can gain a significant amount of performance and cost benefits by optimizing the storage layout (records, objects, partitions) as the data lands into our warehouse. We built AutoOptimize to efficiently and transparently optimize the data and metadata storage layout while maximizing their cost and performance benefits.

As is also the case this limitation is at the database level (especially the storage engine) rather than the hardware level.
