Release Notes

ClickHouse/clickhouse-connect (clickhouse-connect)

v1.1.0

Compare Source

Compatibility

• Async client now requires aiohttp>=3.9.0. This is required to support TLS SNI override via server_host_name, because aiohttp added the per-request server_hostname option in 3.9.
• SQLAlchemy: the alembic extra now requires alembic>=1.16 (previously >=1.9) so the documented IF EXISTS / IF NOT EXISTS Alembic operation kwargs are available.

Bug Fixes

• SQLAlchemy: op.add_column(..., clickhouse_settings={...}) now works through the public Alembic operations API, and rendered AddColumnOp migrations preserve extra ClickHouse kwargs.
• SQLAlchemy: Alembic migrations now handle comments with ClickHouse-compatible syntax. Column comments on CREATE TABLE / ADD COLUMN no longer emit rejected COMMENT ON COLUMN statements; table comments are now emitted in generated DDL, reflected for no-op autogenerate, and changed or dropped with ALTER TABLE ... MODIFY COMMENT.
• Async client: server_host_name now also overrides the TLS SNI / certificate hostname, matching the sync client. Previously the async path only applied it to the HTTP Host header, so connecting to host A while presenting SNI B (the 0.x pool_mgr=urllib3.PoolManager(server_hostname=...) pattern, useful for ClickHouse Cloud VPC endpoints reached via external DNS) was not expressible against the new aiohttp-based client. Both _raw_request and ping() now pass ssl=self._ssl_context, server_hostname=self.server_host_name per request when an SSL context is in use. Closes #​752.
• Drain the full retries budget on connection-error retries in _raw_request instead of only retrying once. Previously both the sync and async clients gated network-error retries on attempts == 1, so two consecutive aiohttp.ServerDisconnectedErrors (or ConnectionResetErrors on the sync path) surfaced as OperationalError even when query_retries would have allowed another attempt. Read paths now drain query_retries; insert/command paths still get one retry (retries=0 callers). Sync raw_query and raw_stream (the foundation for query_arrow / query_arrow_stream) now also pass query_retries so they match their async counterparts. Adds a 0.1 * attempts backoff between connection-error retries to match the 429/503/504 branch. Closes #​754.
• quote_identifier now re-escapes inputs that start and end with ` or " but contain unescaped inner occurrences of the same quote character, instead of passing them through unchanged. Validly pre-quoted identifiers like backslash or doubled-quote escaping still pass through untouched. Closes #​737.
• SQLAlchemy: quote string-valued engine and operation settings as ClickHouse string literals when rendering SETTINGS clauses. Previously settings like MergeTree(settings={"storage_policy": "hot_cold"}) or op.add_column(..., clickhouse_settings={"mutations_sync": "2"}) emitted unquoted SQL (storage_policy = hot_cold), which ClickHouse rejected. Numeric and boolean settings are unchanged.
• SQLAlchemy: preserve engine settings on reflection. build_engine() previously hardcoded engine.settings = {} even when the reflected DDL contained a SETTINGS clause, so callers reading engine.settings after reflection saw an empty dict. settings is now populated from the parsed engine kwargs, decoding ClickHouse string-literal escapes (\\, \', \n, etc.) and preserving float-valued settings as floats — round-trip parity with the construction path.
• SQLAlchemy: Inspector error messages from get_table_metadata() now report the resolved database name i.e. from currentDatabase() when schema was not provided instead of literal None.
