GreptimeDB Enterprise 25.05

We are pleased to introduce the 25.05 release of GreptimeDB Enterprise.

Feature Highlights​

Elasticsearch Compatibility​

The compatibility layer in GreptimeDB Enterprise for Elasticsearch. This layer allows user to configure GreptimeDB Enterprise as the backend of Kibana UI, for log search, aggregation and dashboard.

Queries supported in this release:

  • match
  • match_all
  • multi_match
  • term
  • terms
  • prefix
  • wildcard
  • regexp
  • range
  • exists
  • bool

Read Replicas​

To serve analytical and other heavy queries better, we introduce dedicated query nodes in this release. These type of nodes are responsible for serve queries only, so we can push them to resource limit without affecting data ingestion.

Thanks to our compute-storage disaggregated architecture, it's not a huge refactoring to add read replicas to current architecture. A new type of datanodes will play the role. It's dedicated to process query workloads. Because data are available on object storage, there will be no data replication between these types of datanodes and those original ones who take writes. User will be able to add hint to their queries to specify whether the query should run on read replicas.

Triggers​

Trigger evaluate data with your predefined rules periodically and invoke webhooks if it matches. This is the initial version of triggers. Of course we designed it to work with Prometheus AlertManager.

CREATE TRIGGER IF NOT EXISTS cpu_monitor
    ON (SELECT host AS host_label, cpu, memory FROM machine_monitor WHERE cpu > 1 and ts >= now() - '5 minutes'::INTERVAL)
        EVERY '5 minute'::INTERVAL
    LABELS (severity = 'warning')
    ANNOTATIONS (summary = 'CPU utilization is too high', link = 'http://...')
    NOTIFY(
        WEBHOOK alert_manager URL 'http://127.0.0.1:9093' WITH (timeout="1m")
    );

Flow Reliability​

Reliability features are added to flow, our light-weighted streaming engine:

  • Task migration: move tasks between flow nodes for load balancing.
