Deep Insight Into Open Source Databases

On this page, we will share with you many deep insights into open source databases, such as the database popularity, database contributors, coding vitality, community feedback and so on.

We’ll also share the SQL commands that generate all these analytical results above each chart, so you can use them on your own on TiDB Cloud following this 10-minute tutorial.

Database contributors

Which countries & regions led the database contributions in 2021?

When did developers contribute?

The heat map below describes the number of push events that occur at a particular point of time (UTC). For each day and hour, the colored boxes indicate the number of push events. The lighter the color, the fewer push events; the darker the color, the more push events. You can learn from this heat map what time is the busiest for contributors, and roughly conclude which country or region distributes the most contributors.
