tigrbl_engine_clickhouse 0.1.1.dev19

Tigrbl engine plugin providing ClickHouse database support.

tigrbl_engine_clickhouse

A ClickHouse engine plugin for tigrbl. This package registers a new engine kind "clickhouse" that tigrbl auto‑discovers via the tigrbl.engine entry‑point group.

Both classes in this package are subclasses of tigrbl's first‑class objects.

Installation

pip install tigrbl_engine_clickhouse

Usage

from tigrbl.engine.engine_spec import EngineSpec

spec = EngineSpec(kind="clickhouse", mapping={
    "host": "localhost",
    "port": 8123,
    "username": "default",
    "password": "",
    "database": "default",
    "secure": False,
})
eng, make_session = spec.build()   # resolved via entry-points
s = make_session()                 # returns a ClickHouseSession (TigrblSessionBase subclass)

# Example query
rows = await s._execute_impl("SELECT 1 AS x")
print(rows)
await s.close()

How it’s wired

• pyproject.toml declares the entry‑point:

  [project.entry-points."tigrbl.engine"]
  clickhouse = "tigrbl_engine_clickhouse:register"
  

• register() (in __init__.py) calls tigrbl.engine.registry.register_engine("clickhouse", clickhouse_engine).
• ClickHouseEngine subclasses tigrbl._concrete._engine.Engine.
• ClickHouseSession subclasses tigrbl.session.base.TigrblSessionBase and uses clickhouse_connect.
