Vector v0.56.0 released on 03-06-2026

Vector v0.56.0 is out now. It delivers new ingestion and delivery features — a Databricks Zerobus sink, a delay transform, configurable HTTP retry behaviour, and zstd compression for Vector-to-Vector traffic.
See the full release notes on the Vector website or the project’s GitHub for installation instructions, examples, and configuration details.
What’s in this release
- databricks_zerobus sink for streaming logs to Databricks Unity Catalog tables (OAuth 2.0 authentication, automatic schema fetching, protobuf batch encoding).
- New delay transform to hold events by a fixed duration or conditionally using VRL; HTTP-based sinks gain a retry_strategy option to control which HTTP status codes trigger retries (with an http sink example).
- Major tag_cardinality_limit enhancements: per_tag_limits, tracking_scope: per_metric, a global max_tracked_keys cap, and the ability to opt entire metrics out of cardinality tracking.
Upgrade notes
- Breaking change: greptimedb_metrics and greptimedb_logs sinks now require GreptimeDB v1.x — upgrade your GreptimeDB instance before upgrading Vector if you use those sinks.
- Fixes and platform packaging: a CPU regression introduced in 0.50.0 has been fixed, and support for installing on RHEL 8 / Rocky Linux 8 / AlmaLinux 8 / CentOS Stream 8 has been restored; if you cannot upgrade GreptimeDB immediately, remain on your current Vector release until the database is updated.
