Highlights of Recent PRs

db#5819 Adds a new HTTP API for querying the pipeline

Introduces a new API: /v1/events/pipelines/{pipeline_name} to retrieve pipeline information by name. Docs. For more details, please refer to this document here.

db#5836 Implements Arrow Flight DoPut method

Enables high-throughput ingestion via Arrow Flight’s DoPut. Arrow Flight is a gRPC-based RPC protocol for efficient data transfer using the Arrow format.

db#5840 Implements the otel-arrow protocol for GreptimeDB

Otel-arrow is the protocol for sending and receiving OpenTelemetry data using Apache Arrow. In this PR, we implement the support for it in GreptimeDB. With otel-arrow, it could be very convenient for GreptimeDB to load large volume of OpenTelemetry data.

db#5903 Adds a new Batching Mode for Flow

This PR adds a new batching mode for Flow. In batching mode, Flow can periodically process and flush data to utilize maximum ingestion volume. It's suitable for large-scale aggregation, reporting, or scheduled jobs with smoother resource consumption.

db#5910 Adds a new JSON parse processor in the pipeline

This PR adds a new processor for parsing JSON strings: json_parse. More details here.

For example, given the following log data:

{
  "product_object": "{\"hello\":\"world\"}",
}

Using the following configuration:

processors:
  - json_parse:
      fields:
        - product_object

The result will be:

{
  "product_object": {
    "hello": "world"
  }
}

Good First Issue

Issue#5899 Support the kill statement
