dennis zhuang 9f906da091 feat(promql): run time(), vector(s) and data-free scalar broadcasts natively (#9988)
* feat(promql): run time(), scalar(v), vector(s) and dynamic scalar broadcasts natively

Bind time() and zero-argument date functions as EvalTime, scalar(v) as ScalarOf and
vector(s) as VectorOf, and run binary operations whose scalar side varies per grid point:
the scalar is read whole, vector chunks that arrive before it are held and charged, and
both operand orders and bool comparisons follow Prometheus.

A tree holding scalar(v) runs as one execution over every scan partition, and the
planner admits it only over an unpartitioned Mito table. Data-free statements plan
without a scan.

* fix(promql): hold the labels of chunks waiting for a varying scalar

* feat(promql): read round and clamp parameters from varying scalars natively

Bind round, clamp, clamp_min and clamp_max whose parameters are not all constants as a
ParameterizedMap with scalar parameter nodes, run through map_math_with_parameters. The
parameters are read whole first; vector chunks that arrive before them are held and
charged, through the same hold the varying-scalar broadcast now shares. Constant
parameters keep the MathOp map.

* test(promql): pin a parameterized map's empty closing chunk

Also correct the held-chunk docs, use same-table examples for varying map parameters,
and assert the native decline instead of the existing planner's failure.

* fix(query): plan vector(s) natively whatever the table's field is named

The fused route declined a root field that is not a raw field, which is every root over
vector(s): it names its result `value`. Take the compiled root's fields as they are and
decline only a name the output already gives a tag or the time index.

* refactor(promql): leave scalar(v) to the existing planner until it has its own execution boundary

* fix(promql): leave data-free statements that generate labels to the existing plan

* fix(promql): reserve the output point-wise kernels build before running them

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.
