There was a problem hiding this comment.
Confluent provides these as suffixes we may want to just suggest .*<suffix> for each AZ.
This is a screenshot for a long deleted confluent cluster with privatelink setup... the subdomains are the suffixes.

## Follow up of #35455 ## Summary - Adds `BOOTSTRAP BROKER 'addr' USING AWS PRIVATELINK conn (...)` — new top-level option that provides the initial bootstrap address with an explicit PrivateLink tunnel, preserving the real hostname for correct TLS SNI - Adds `MATCHING 'pattern' USING AWS PRIVATELINK conn (...)` inside `BROKERS (...)` — pattern-based routing rules for dynamically discovered brokers returned in Kafka metadata - Replaces the `AWS PRIVATELINKS` syntax which used a `TO` keyword inconsistent with the existing `USING AWS PRIVATELINK` syntax and overloaded exact-match patterns as implicit bootstrap addresses - Updates parser, planner, and storage layer to support the new constructs ### Example ```sql CREATE CONNECTION kafka TO KAFKA ( BROKERS ( 'lkc-825730.endpoint.cloud:9092' USING AWS PRIVATELINK pl_conn, MATCHING '*use1-az1*' USING AWS PRIVATELINK pl_conn (AVAILABILITY ZONE 'use1-az1'), MATCHING '*use1-az4*' USING AWS PRIVATELINK pl_conn (AVAILABILITY ZONE 'use1-az4'), MATCHING '*use1-az6*' USING AWS PRIVATELINK pl_conn (AVAILABILITY ZONE 'use1-az6') ), SASL MECHANISMS 'PLAIN', SASL USERNAME 'key', SASL PASSWORD SECRET secret, SECURITY PROTOCOL 'SASL_SSL' ); ``` ## Test plan - [x] Parser tests updated (roundtrip, error cases) - [x] Testdrive updated (connection-create-drop, connection-alter) - [x] `cargo check` passes - [x] Cloudtest validation ([see follow-up PR](#36162)) - [ ] Manual testing against Confluent Cloud PrivateLink ## Docs - [ ] #36163 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
