We had specializations in hardware, operating systems, databases, graphics, etc. Jim Mauro and Allan Packer visited on rotation from New Jersey, and Adelaide Australia, and worked out how to produce a database sizing guide for Oracle Financials, which I wrote up and published. Jim also joined the database performance team.

Are you looking to get started with the world’s most popular open-source database, and wondering how you should setup your MySQL hosting ? So many default to Amazon RDS, when MySQL performs exceptionally well on Azure Cloud. MySQL DBaaS vs. Self-Managed MySQL. A good example would be slow query analysis. High Availability Deployment.

MongoDB is the #3 open source database and the #1 NoSQL database in the world. It’s a cross-platform document-oriented database that uses JSON-like documents with schema, and is leveraged broadly across startup apps up to enterprise-level businesses developing modern apps.

PgBouncer defines one pool per user+database combination. A client benefits from a pooled connection only if it connects to a child which has previously served a connection for this database+user combination. PgBouncer allows limiting connections per-pool, per-database, per-user or per-client. Performance Testing.

Fortunately, chaos engineering is definitely not only useful in cloud native environments – it can also be used for monolithic services on virtual machines. As it seems like many techniques used in chaos engineering might be covered in other disciplines – like vulnerability or performance testing – where the difference is.

In that environment, the first PostgreSQL developers decided forking a process for each connection to the database is the safest choice. It would be a shame if your database crashed, after all. Developers are often strongly discouraged from holding a database connection while other operations take place.

Firstly, start by installing the Dynatrace OneAgent on the hosts where you’ll be running your application test. If you have a distributed environment with multiple servers hosting your webservers, app servers, and database, I suggest you install the OneAgent on all these servers to get full end-to-end visibility.

As with the previous guides as an Intel employee (#IAMINTEL) the examples are taken from a MySQL 8 on Linux on Intel system and the approach is the same for whatever system you are testing although some of the settings you see may be different. Similarly for this guide MySQL can be swapped for a mySQL based databases such as MariaDB.

Plotting the percent performance loss vs syscall rate per CPU, for my microbenchmark: Applications that have high syscall rates include proxies, databases, and others that do lots of tiny I/O.
