Release v1.1.2

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.
