We have a detailed howto for your first steps with SQL databases in DSS.
You might want to start with that Howto. The rest of this page is reference information for PostgreSQL.
DSS supports the full range of features on PostgreSQL:
- Reading and writing datasets
- Executing SQL recipes
- Performing visual recipes in-database
- Using live engine for charts
DSS only supports PostgreSQL 9 and 10 (all minor versions). PostgreSQL 8 is not supported.
Computing column statistics metrics on PostgreSQL datasets requires a version 9.4 or greater.
Installing the JDBC driver¶
The PostgreSQL driver is pre-installed in DSS. You don’t need any further installation.
Secure connections (SSL / TLS) support¶
DSS can connect to a PostgreSQL server using secure connections.
Setup with certificate validation (recommended)¶
Importing the server certificate¶
You first need to obtain and convert the server certificate. Please follow the instructions laid out here:
The server certificate should be added to the truststore of the JVM used by DSS, using one of the procedures described at Adding SSL certificates to the Java truststore.
Setting up the PostgreSQL connection¶
In the settings of the connection, add an “Advanced property”:
Setup without certificate validation (not recommended)¶
Setting up SSL connection without certificate connection is much simpler, but by removing certificate validation, you loose the protection that SSL provides, since an internal attacker could still be able to impersonate the server
In the settings of the connection, add the following 2 “Advanced properties”:
