[Legacy] CrateDB Clients and Tools

CrateDB is a distributed SQL database that makes it simple to store and analyze massive amounts of machine data in real-time.

We are also maintaining a more up-to-date list of CrateDB integration tutorials.

Tip

CrateDB supports the PostgreSQL wire protocol. Accordingly, many clients that work with PostgreSQL also work with CrateDB.

You can try this out for yourself:

• Configure a PostgreSQL connection, but point your client to a CrateDB server instead of a PostgreSQL server

• Authenticate as the crate superuser with no password

• Specify the doc schema, if you are asked for a database name

• For example, your connection string to a local database might look like postgresql://crate@localhost:5432/doc

Check out the client compatibility notes and implementation differences for information about known limitations.

If you run into issues, please let us know using the Feedback section at the bottom of this page. We regularly update CrateDB to accomodate new PostgreSQL clients.

Tools

CrateDB integrates with many different tools. Some of these are:

• Azure Functions

  An Azure Function is a short-lived, serverless computation that is triggered by external events. Learn how to create a data enrichment pipeline in our tutorial.

• Grafana

  Grafana allows you to query, visualize, alert on and understand your metrics and time series data. Read our tutorial on how to pair CrateDB with Grafana.

• Pentaho

  Pentaho prepares and blends data, delivering business analytics from any source. You can connect to CrateDB clusters by using Pentaho Kettle and the standalone version of our JDBC driver.

• R

  R is a programming language and software environment geared towards statistical computing. Read our guide on how to create a Machine Learning pipeline.

• SQLPad
