londonaicentre-mesa-runner 1.2.2

A stateless runner / deployment system for MESA models

MESA Runner

A stateless runner for deploying MESA registered models onto GSTT Infrastructure. It syncs models from S3, reads unprocessed documents from Snowflake, runs inference, and writes results back.

Requirements

• Python 3.13+
• uv package manager

Installation

Remote Inference (Default)

For remote inference via OpenAI-compatible endpoints:

uv sync

Offline Inference (Optional)

For local GPU inference with vLLM, install the optional dependency:

uv sync --group vllm-offline

Configuration

Create a config.yaml file (see example below):

Remote Inference Example

my_source:
  model_name: "your-model-name"

  inference:
    openai_endpoint: "http://localhost:5000/v1"

  storage:
    type: snowflake
    source_database: "str"
    source_schema: "str"
    source_table: "str"

    sink_database: "str"
    sink_schema: "str"
    sink_table: "str"

    connection_params:
      account: "str"
      user: "str"
      role: "str"
      password: "str"
      warehouse: "str"
      database: "str"

Offline Inference Example

my_source:
  model_s3_uri: "s3://aicentre-nlpteam-mesa-build/models/oncoqwen/oncoqwen_1/"

  inference:
    max_model_len: 18000

  storage:
    type: snowflake
    source_database: "str"
    source_schema: "str"
    source_table: "str"

    sink_database: "str"
    sink_schema: "str"
    sink_table: "str"

    connection_params:
      account: "str"
      user: "str"
      role: "str"
      password: "str"
      warehouse: "str"
      database: "str"

Usage

# Run with default config.yaml
mesa_runner

# Or specify a config file
mesa_runner --config /path/to/config.yaml

# Dry run mode (uses dummy data, does not read or write real data)
mesa_runner --dry-run

The dry run mode is useful for testing the runner without accessing real data sources or sinks. It generates 5 dummy documents by default and logs all write operations instead of executing them.

Docker

# Remote inference (default)
docker build -t mesa-runner .
docker run mesa-runner

# Offline inference (includes vLLM)
docker build --target offline -t mesa-runner:offline .
docker run --gpus all mesa-runner:offline
