We can start by dialing traffic in a single data center to allow for an easier side-by-side comparison of key metrics across data centers, thereby making it easier to observe any deviations in the metrics. One can perform this comparison live on the request path or offline based on the latency requirements of the particular use case.

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. By default, MongoDB provides a snappy block compression method for storage and network communication.

JSONB supports indexing the JSON data, and is very efficient at parsing and querying the JSON data. JSONB storage has some drawbacks vs. traditional columns: PostreSQL does not store column statistics for JSONB columns. JSONB storage results in a larger storage footprint. It is a decomposed binary format to store JSON.

Character encoding refers to the method used to represent characters as binary data for storage and transmission. The choice of character set and encoding impacts not only efficiency but also how the data appears to users. This difference in storage size can lead to variations in the size of index entries, which can impact efficiency.
