ClickHouse Endpoint

ClickHouse endpoints connect Eve to ClickHouse clusters for governed analytical queries, telemetry exploration, and high-volume operational analytics.

Endpoint Kind

Use clickhouse as the endpoint kind when creating this endpoint through the API or dashboard.

What Eve Uses ClickHouse Endpoints For

Run governed analytical SQL against ClickHouse.
Expose operational and product analytics to Adam and approved tools.
Centralize credential handling for ClickHouse HTTP access.
Combine ClickHouse data with Datadog, PostHog, Snowflake, and LLM workflows.

Basic Endpoint Shape

json

{
  "endpoint": "clickhouse-prod",
  "kind": "clickhouse",
  "config": {
    "read_conn": {
      "host": "clickhouse.internal",
      "port": 8123,
      "user": "default",
      "password": "secret",
      "database": "default"
    }
  },
  "description": "Production ClickHouse analytics"
}

Create it with the endpoint API:

bash

curl -sS -X POST "$EDEN/endpoints" \
  -H "$AUTH_HEADER" \
  -H "Content-Type: application/json" \
  -d '{
    "endpoint": "clickhouse-prod",
    "kind": "clickhouse",
    "config": {
      "read_conn": {
        "host": "clickhouse.internal",
        "port": 8123,
        "user": "default",
        "password": "secret",
        "database": "default"
      }
    },
    "description": "Production ClickHouse analytics"
  }'

Configuration Fields

Field	Purpose
`host`	ClickHouse host.
`port`	HTTP interface port, usually `8123`.
`user`	Username, often `default` in local setups.
`password`	Password.
`database`	Default database.

Operating Notes

Use query limits and read-only users for exploratory and agent-facing access.
Watch expensive scans, distributed query fanout, and memory settings.
Keep production telemetry endpoints separate from local development ClickHouse instances.
