There are a lot of things I love about Prometheus; its data model is fantastic for monitoring applications and PromQL language is often more expressive than SQL for data retrieval needs you have in the observability space.

Any performance feature in PostgreSQL that mentions the “parallel” keyword excites me. So it was natural that parallel vacuum took my complete attention when it was committed in January 2020.

I will try to make it short and clear: if you are writing SQL queries with “NOT IN” like SELECT … WHERE x NOT IN (SELECT y FROM …) you have to be sure to first understand what happens when “x” or “y” are NULL: it might not be what you want! And if it is not, I will tell you here ho

I decided to write this off the back of a conversation I was having the other day around the SOS_SCHEDULER_YIELD wait type. The conversation went something along the lines of “but David, I’m seeing SOS_SCHEDULER_YIELD, we must have CPU issues”.

In this article, I have explained the step by step process of migrating data from SQL Server to Azure Cosmos database. To perform database migration, we will proceed in the following manner: To understand the data migration process, I have explained it into multiple steps.

Trends in cloud data storage continue to accelerate at a rapid pace. Now more than ever, organizations must evaluate their current and future data storage needs to find solutions that align with business goals.
