Databricks Connector

Native Irodori Table connector extension for Databricks.

This crate packages the connector metadata, native ABI exports, and driver implementation used by the Irodori extension marketplace.

Connector

• Extension ID: irodori.databricks
• Engine ID: databricks
• Wire protocol: jdbc
• Default port: 443
• Native ABI: irodori.connector.native.v1
• Driver linked: yes
• Marketplace visibility: public
• Package version: 0.1.3

The package uses the connector metadata and native driver directly; no desktop adapter source snapshot is required.

Connector metadata lives in connector.config.json and irodori.extension.json. The Rust crate exports the native ABI from src/lib.rs, uses irodori-connector-abi for shared JSON/buffer helpers, and keeps connector behavior in src/driver.rs.

Connection Metadata

• Endpoint modes: hostPort, connectionString
• Transport modes: direct, sshTunnel, socks5Proxy, httpConnectProxy, proxyChain
• TLS supported: yes
• TLS required by default: yes
• Custom driver options: yes

Endpoint Fields

Field	Label	Type	Required
host	Host	string	yes
port	Port	number	no
httpPath	HTTP path	string	yes
database	Schema	string	no
catalog	Catalog	string	no

Authentication

The connector advertises these authentication modes so clients can render the right credential fields. Driver-specific or provider-specific values can still be passed through options when needed.

Auth method	Label	Kind	Secret purposes
none	No authentication	none	none
connectionString	Connection string / DSN	connectionString	none
databricksPersonalAccessToken	Databricks personal access token	token	token
databricksOAuthToken	Databricks OAuth token	oauth2	token
databricksOAuthU2M	Databricks OAuth user-to-machine	browserSso	password
databricksOAuthM2M	Databricks OAuth machine-to-machine	oauth2	token
databricksAzureManagedIdentity	Databricks Azure managed identity	managedIdentity	none
customDriverOptions	Custom driver options	custom	password, token, privateKey, privateKeyPassphrase

Native ABI Calls

Method	Response
health	Returns connector health, engine id, ABI version, and driver status.
describe	Returns the embedded manifest and connector config.
manifest	Returns raw irodori.extension.json.
config	Returns raw connector.config.json.
connect	Opens and validates a native connector connection.
query	Runs a connector query and returns structured rows or JSON results.
metadata	Reads schemas, tables, columns, indexes, collections, or equivalent metadata.
close	Closes and removes a cached native connection.

Development

All extension crates in this checkout share ../target so dependencies compile once across sibling repositories.

make check
make build

Release packages place platform-specific native artifacts under dist/native.
