• Limitations
• Key bindings
• Configuration
• Workspace configuration

Quick start

Open workspace (workspace path is needed for configuration to generate), activate extension by running command from palette Cassandra Workbench: Generate configuration. This will generate .cassandraWorkbench.jsonc configuration file.

Switch to Cassandra worbench panel by clicking activity bar icon. Edit .cassandraWorkbench.jsonc to suit your needs. (configuration)

Editor UI

Limitations

Multiple SELECT statements per script are not allowed. You will be notified by message:

Unable to execute multiple SELECT statements

Mixing SELECT statements with data/structure altering statements is not allowed. You will be notified by message:

Unable to execute SELECT statement along with data or structure altering statements

Key bindings

Configuration

.cassandraWorkbench.jsonc file contains array of cluster connection items.

Authentication modes, currently supported (more info):

• AllowAllAuthenticator
• PasswordAuthenticator

When using PasswordAuthenticator, user, used to connect, must have SELECT permissions to access:

• Cassandra 3.*
  • system_schema keyspace
• Cassandra 2.*
  • system.schema_aggregates
  • system.schema_columnfamilies
  • system.schema_columns
  • system.schema_functions
  • system.schema_keyspaces
  • system.schema_triggers
  • system.schema_usertypes

Default configuration (generated by Cassandra Workbench: Generate configuration):

// name must be unique!
[
    // AllowAllAuthenticator
    {
        "name": "Cluster AllowAllAuthenticator",
        "contactPoints": ["127.0.0.1"]
    },
    //PasswordAuthenticator
    {
        "name": "Cluster PasswordAuthenticator",
        "contactPoints": ["127.0.0.1"],
        "authProvider": {
            "class": "PasswordAuthenticator",
            "username": "yourUsername",
            "password": "yourPassword"
        }
    }
]

Add/remove and reconfigure cluster items as needed.

Workspace configuration

cassandraWorkbench.excludeKeyspaces: string[] - default []

• list of regexp pattern to exclude when listing keyspaces in panel

To exclude system keyspaces use:

    "cassandraWorkbench.excludeKeyspaces": [
            "^system$",
            "^system_auth$",
            "^system_distributed$",
            "^system_traces$",
            "^system_schema$"
        ]

cassandraWorkbench.useWorkspace : number - default 0

• index of workspace where to look for configuration file .cassandraWorkbench.jsonc. For multi-root only.
