SQL

Selecting a SQL Datastore

Tarmac has support for multiple SQL datastore storage systems. These datastores can change with basic configuration options within Tarmac. As a WASM Function developer, you do not need to know the underlying datastore when writing the function. Callbacks for accessing the SQL datastore are generic across all supported datastores.

To start using a SQL datastore, set the enable_sql configuration to true and specify which supported platform to use with the sqlstore_type variable.

The below table outlines the different available options.

Datastore	Type option	Description	Useful for
MySQL	mysql	MySQL a widely used, open-source RDBMS	Strong Consistency, Well Known, Persistent Storage, Scales Well
PostgreSQL	postgres	PostgreSQL a widely used, open-source RDBMS	Strong Consistency, Well Known, Persistent Storage, Scales Well
