Coherence Python API Docs | dltHub
Build a Coherence-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.
Last updated:
Coherence API reference details scripting API for Unity. The coherence platform provides tools for multiplayer game development. Oracle Coherence Java API Reference defines classes for XML processing and object models. The REST API base URL is http://<host>/management/coherence and Authentication is performed via HTTP basic auth or container‑level security; no public bearer token is required for the management REST API..
dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv pip install "dlt[workspace]" and start loading Coherence data in under 10 minutes.
What data can I load from Coherence?
Here are some of the endpoints you can load from Coherence:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| platform_memory | cluster/platform/memory | GET | Returns aggregated platform memory statistics for the cluster. | |
| member_platform_memory | cluster/members/{memberIdentifier}/platform/memory | GET | Returns JVM memory information for a specific cluster member. | |
| services | cluster/services | GET | Lists all services running in the cluster. | |
| caches | cluster/caches | GET | Provides a list of cache names and basic metadata. | |
| members | cluster/members | GET | Retrieves information about all members in the cluster. |
How do I authenticate with the Coherence API?
Requests should include an Authorization header with HTTP Basic credentials (username and password) unless the server is configured for anonymous access.
1. Get your credentials
- Log in to the Oracle Coherence administration console or the application server console.
- Navigate to the Security or Users section.
- Create or locate a user account that has permission to access the management REST endpoints.
- Note the username and password for this account; they will be used as HTTP Basic credentials when calling the API.
- Optionally, configure the server to require HTTPS for added security.
2. Add them to .dlt/secrets.toml
[sources.coherence_source] username = "your_username" password = "your_password"
dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.
How do I set up and run the pipeline?
Set up a virtual environment and install dlt:
uv venv && source .venv/bin/activate uv pip install "dlt[workspace]"
1. Install the dlt AI Workbench:
dlt ai init --agent <your-agent> # <agent>: claude | cursor | codex
This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →
2. Install the rest-api-pipeline toolkit:
dlt ai toolkit rest-api-pipeline install
This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →
3. Start LLM-assisted coding:
Use /find-source to load data from the Coherence API into DuckDB.
The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.
4. Run the pipeline:
python coherence_pipeline.py
If everything is configured correctly, you'll see output like this:
Pipeline coherence_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset coherence_data The duckdb destination used duckdb:/coherence.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs
Inspect your pipeline and data:
dlt pipeline coherence_pipeline show
This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.
Python pipeline example
This example loads platform_memory and member_platform_memory from the Coherence API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:
import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def coherence_source(username=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "http://<host>/management/coherence", "auth": { "type": "http_basic", "": username, }, }, "resources": [ {"name": "platform_memory", "endpoint": {"path": "cluster/platform/memory"}}, {"name": "member_platform_memory", "endpoint": {"path": "cluster/members/{memberIdentifier}/platform/memory"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="coherence_pipeline", destination="duckdb", dataset_name="coherence_data", ) load_info = pipeline.run(coherence_source()) print(load_info)
To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.
How do I query the loaded data?
Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.
Python (pandas DataFrame):
import dlt data = dlt.pipeline("coherence_pipeline").dataset() sessions_df = data.platform_memory.df() print(sessions_df.head())
SQL (DuckDB example):
SELECT * FROM coherence_data.platform_memory LIMIT 10;
In a marimo or Jupyter notebook:
import dlt data = dlt.pipeline("coherence_pipeline").dataset() data.platform_memory.df().head()
See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.
What destinations can I load Coherence data to?
dlt supports loading into any of these destinations — only the destination parameter changes:
| Destination | Example value |
|---|---|
| DuckDB (local, default) | "duckdb" |
| PostgreSQL | "postgres" |
| BigQuery | "bigquery" |
| Snowflake | "snowflake" |
| Redshift | "redshift" |
| Databricks | "databricks" |
| Filesystem (S3, GCS, Azure) | "filesystem" |
Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
