v1.1.2

Release date: July 02, 2026

GreptimeDB v1.1.2 is a patch release for the v1.1 line. It fixes scheduled Flow runtime semantics, improves slow-query context, and refreshes the bundled dashboards.

We recommend users on v1.1.0 and v1.1.1 upgrade to v1.1.2.

👍 Highlights

Scheduled Flow execution now uses stable logical time. Flows with EVAL INTERVAL now bind now() and current_timestamp() to the scheduled runtime, including distributed plans. This keeps scheduled windows stable instead of depending on when a worker happens to plan the query.

CREATE TABLE flow_input (
  ts TIMESTAMP(3) TIME INDEX,
  v DOUBLE,
  PRIMARY KEY(v)
);

CREATE FLOW flow_eval
SINK TO flow_eval_sink
EVAL INTERVAL '1s'
AS
SELECT
  date_bin(INTERVAL '1 second', ts) AS window_start,
  count(v) AS value_count,
  now() AS scheduled_at
FROM flow_input
WHERE ts >= date_trunc('second', now()) - INTERVAL '1 second'
  AND ts <  date_trunc('second', current_timestamp())
GROUP BY date_bin(INTERVAL '1 second', ts);

Slow query records include schema context. Slow query entries now carry the schema name for SQL, logical plan, and PromQL slow-query paths. This makes it easier to find which tenant or workload produced a slow query when multiple schemas share a cluster.

USE greptime_private;

SELECT schema_name, cost, threshold, query, timestamp
FROM slow_queries
ORDER BY timestamp DESC
LIMIT 10;

Dashboard

Bundled Grafana metrics dashboards were reorganized for cluster and standalone deployments. The update fixes histogram bucket queries and counter-rate normalization, separates latency panels, and collapses flush/compaction sections to make troubleshooting easier.
The embedded GreptimeDB dashboard was updated to v0.13.6. This dashboard release refines metric views and fixes SQL execution from the editor when the cursor is after a SQL line.
