Description
QuestDB is the fastest growing open-source time-series database offering blazingly fast, high throughput ingestion and dynamic, low-latency SQL queries. The entire high-performance codebase is built from the ground up in Java, C++ and Rust with no dependencies and zero garbage collection.
We achieve high performance via a column-oriented storage model, parallelized vector execution, SIMD instructions, and low-latency techniques. In addition, QuestDB is hardware efficient, with quick setup and operational efficiency.
QuestDB implements ANSI SQL with native time-series SQL extensions. These SQL extensions make it simple to analyze, filter and downsample data, or to correlate data from multiple sources using relational and time-series joins.

How to use this image
$ docker run -p 9000:9000 -p 8812:8812 questdb/questdbOpen localhost:9000 to access the QuestDB Web Console.
This starts QuestDB with the default configuration and without any persistent volume. This means that all data will be lost when the container is stopped.
Volumes
In order to persist data, you can mount a directory or a volume using the -v parameter:
$ docker run -p 9000:9000 -p 8812:8812 -v local/dir:/var/lib/questdb questdb/questdbReplace local/dir with the absolute path to the directory on your host machine where you want to persist the data.
Exposed ports
This is the list of ports used by QuestDB:
- 9000 for the InfluxDB Line Protocol, REST API and the Web Console (accessible at localhost:9000)
- 8812 for the Postgres wire protocol
Configuration
When you mount an empty volume as explained above, QuestDB will create a default configuration file inside the mounted volume. You can then edit this file to customize the configuration. Alternatively, you can use environment variables to configure QuestDB.
