discord9 fa7056eae7 feat(promql): match an empty on() and grouped cardinalities natively (#10223)
The compiler already carries an empty `on()` and both grouped cardinalities,
and the matcher kernel implements them; only the planner's narrow region-local
allowlist refused them, so those queries fell back. Admit them: the pair is
planned as one native binary over the two operands, matching above their
sources.

Admitting them exposed an output-schema bug the allowlist was hiding: both tag
walks treated an empty `on()` as "keep every tag", so the output carried
labels the kernel had dropped. They now keep only the specified labels, and a
grouped match keeps the many side's labels and copies the included ones from
the one side.

Tests: the empty-`on()` subtraction and the `group_left()` form assert native
execution with their original rows and labels, and four cases assert the
kernel's cardinality errors - duplicate right under `on()` and `group_left()`,
an implicit many-to-one under `on()`, and duplicate left under `group_right()`.
The subquery case in the same loop keeps its fallback.

Setup tests for multiple storage backend

To run the integration test, please copy .env.example to .env in the project root folder and change the values on need.

Take s3 for example. You need to set your S3 bucket, access key id and secret key:

# Settings for s3 test
GT_S3_BUCKET=S3 bucket
GT_S3_REGION=S3 region
GT_S3_ACCESS_KEY_ID=S3 access key id
GT_S3_ACCESS_KEY=S3 secret access key

Run

Execute the following command in the project root folder:

cargo test integration

Test s3 storage:

cargo test s3

Test oss storage:

cargo test oss

Test azblob storage:

cargo test azblob

Setup tests with Kafka wal

To run the integration test, please copy .env.example to .env in the project root folder and change the values on need.

GT_KAFKA_ENDPOINTS = localhost:9092

Setup kafka standalone

cd tests-integration/fixtures

docker compose -f docker-compose.yml up kafka

Setup tests with etcd TLS

This guide explains how to set up and test TLS-enabled etcd connections in GreptimeDB integration tests.

Quick Start

TLS certificates are already at tests-integration/fixtures/etcd-tls-certs/.

  1. Start TLS-enabled etcd:

    cd tests-integration/fixtures
    docker compose up etcd-tls -d
    
  2. Start all services (including etcd-tls):

    cd tests-integration/fixtures
    docker compose up -d --wait
    

Certificate Details

The checked-in certificates include:

  • ca.crt - Certificate Authority certificate
  • server.crt / server-key.pem - Server certificate for etcd-tls service
  • client.crt / client-key.pem - Client certificate for connecting to etcd-tls

The server certificate includes SANs for localhost, etcd-tls, 127.0.0.1, and ::1.

Regenerating Certificates (Optional)

If you need to regenerate the etcd certificates:

# Regenerate certificates (overwrites existing ones)
./scripts/generate-etcd-tls-certs.sh

# Or generate in custom location
./scripts/generate-etcd-tls-certs.sh /path/to/cert/directory

If you need to regenerate the mysql and postgres certificates:

# Regenerate certificates (overwrites existing ones)
./scripts/generate_certs.sh

# Or generate in custom location
./scripts/generate_certs.sh /path/to/cert/directory

Note: The checked-in certificates are for testing purposes only and should never be used in production.
