External Data Source Management (datasource)

The datasource command browses and tests external data sources configured in Studio (MySQL, PostgreSQL, Kafka, etc.). It is commonly used to validate connections before configuring sync tasks:

List all configured data sources:

cz-cli -p prod datasource list

Test data source connectivity:

cz-cli -p prod datasource test <datasource_name>

Browse databases/schemas in a data source:

cz-cli -p prod datasource catalogs <datasource_name>

Browse tables in a specific database:

cz-cli -p prod datasource objects <datasource_name> <catalog_name>

View metadata for a specific table:

cz-cli -p prod datasource describe <datasource_name> <catalog_name> <table_name>

Preview sample data from a table:

cz-cli -p prod datasource sample <datasource_name> <catalog_name> <table_name>
