dennis zhuang 5b17bbd584 feat(promql): run info() natively (#10005)
* feat(promql): run info() natively

info(v, {selector}) fell back to the existing plan, which has no info
and refuses the query ("Unsupported expr type: info", or "Cannot accept
multiple vector as function input" when a selector is given).

Compile it into the native tree and run it on the info kernel:

- Plan: NativeExpr::Info { base, info, selector }. The info side is an
  instant selection reporting each selected sample's own time in
  milliseconds (InstantValue::InfoTimestamp, which replaces the
  BoundInstant.timestamp flag); validation refuses any other info side.
- Compiler: info_input derives the info selector the way Prometheus
  does: target_info or one __name__="..." matcher, the data matchers,
  and the @ and offset every selector of the first argument shares
  (subquery offsets added until an @ anchors them, none when they
  differ). Regex or negative name matchers, which can select several
  tables, __field__/__schema__/__database__ matchers and multi-field
  info tables are refused. The planner's selector walk uses the same
  helper, so both bind the info table as the last input.
- Runtime: BinaryRuntime runs the kernel as PairKernel::Info, with the
  retention and pool accounting of binary and set nodes; the kernel
  reports its workspace through info_with_reservation.
- Planner: the info table is a second table, so it is read through its
  own RawSeriesSource and the node runs on the frontend. The output adds
  the info table's tags, or only the data labels the selector names.
  Partitioned or non-Mito tables and a missing info table keep the
  existing plan.

* test(promql): pin region-local placement of info over its own table

info(rate(target_info[5m])) reads the info table twice. Check that the
planner binds both as direct scans under one FusedSeries node bound to
the table, that the node is placed in the region, and the columns it
reports.

* fix(promql): keep sample-less base series out of info's identifying patterns

* fix(promql): share identifying label strings in info() instead of copying 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.
