These large unstructured blogs are not efficient for querying, so we need to transform and store this data in a different format to allow efficient queries. One might think that normalizing it would make storage and querying more efficient, albeit at the cost of writing more complex queries.

But, manual steps — such as reviewing test results and addressing production issues resulting from performance, resiliency, security, or functional issues — often hinder these efforts. As two examples, Roman Ferstl of Triscon noted that observability-driven DevOps has helped clients achieve 15x more tests with 10x more apps tested.

To test the performance of your solution, you’ll need to populate the table with larger volumes of sample data. numgroups AS INT = 1000 , @rowspergroup AS INT = 10000 , -- test with 1000 to 10000 here. My test machine has four logical CPUs, running SQL Server ® 2019 Enterprise. uniquevalues AS INT = 5 ; ALTER TABLE dbo.

Using a connection pool in each module is hardly efficient: Even with a relatively small number of modules, and a small pool size in each, you end up with a lot of server processes. Our tests show that even a small number of clients can significantly benefit from using a connection pooler. The architecture of a generic connection-pool.

And while our environments have exploded in terms of complexity, we’ve reduced the number of production issues reported by our customers to around 7%, and we deploy about five thousand times per day in production-like environments to continuously test our platform. How did we achieve that? The Dynatrace way.

This is just one of many use cases that MezzFS supports, but all the use cases share a similar theme: stream the right bits of a remote object efficiently and expose those bits as a file on the filesystem. MezzFS collects metrics on data throughput, download efficiency, resource usage, etc. Its logs are collected in an ELK stack.
