chore(deps)(deps-dev): update clickhouse-connect requirement from <1,>=0.7 to >=0.7,<2

[dependabot]

Updates the requirements on clickhouse-connect to permit the latest version.

Release notes

Sourced from clickhouse-connect's releases.

v1.0.1

clickhouse-connect 1.0.1

If you are upgrading from 0.15.x or earlier, see MIGRATION.md for the 1.0 breaking changes.

What's Changed

Bug Fixes

• Recognize Fixed/UTC±HH:MM:SS timezones emitted by ClickHouse servers without an IANA tz database (in column types, the X-ClickHouse-Timezone header, and SELECT timezone()). Previously these raised ProgrammingError on any column read, parameter bind, or client init that touched one. The exact ±24:00:00 boundary remains rejected because Python's datetime.timezone cannot represent it. Closes #702.
• Async client: drain in-flight requests before closing the underlying aiohttp session. Sharing a single AsyncClient across concurrent coroutines previously raised RuntimeError: Session is closed (and related Connection reset / QUERY_WITH_SAME_ID_IS_ALREADY_RUNNING cascades) whenever max_connection_age triggered a pool rotation while other tasks had requests in flight. close_connections() now installs the new session before retiring the old one, and waits for outstanding requests (including streaming responses) to release their lease before tearing it down. close() clears self._session so post-close calls fail with ProgrammingError instead of leaking aiohttp's RuntimeError. Closes #744.
• Async client: ca_cert="certifi" shorthand now resolves to certifi.where(), matching the sync client. Previously the async path passed the literal string to ssl_context.load_verify_locations, producing FileNotFoundError. Closes #742.
• SQLAlchemy: render ILIKE and NOT ILIKE expressions using native ClickHouse syntax instead of the generic SQLAlchemy lower(...) LIKE lower(...) fallback.

1.0.0, 2026-05-13

No code changes since 1.0.0rc3. See the 1.0.0rc1, 1.0.0rc2, and 1.0.0rc3 entries below for the full set of changes included in the 1.0.0 release.

Upgrading from a 0.15.x or earlier release? See https://github.com/ClickHouse/clickhouse-connect/blob/main/MIGRATION.md for a guide to the breaking changes and their replacements.

1.0.0rc3, 2026-05-07

Bug Fixes

• Fix intermittent Code: 62. Empty query. (SYNTAX_ERROR) on inserts when a pooled keep-alive connection is reset between attempts. The retry path now rebuilds the insert body instead of replaying an already-drained generator. Affects both sync and async clients. Closes #731

1.0.0rc2, 2026-05-05

Improvements

• Order-of-magnitude faster DateTime and DateTime64 reads for naive UTC and UTC-equivalent timezones. The Cython read paths now decode via epoch arithmetic and construct datetime objects directly via the CPython datetime C API, bypassing datetime.fromtimestamp and the Python-level datetime(...) constructor. Also fixes Cython DateTime conversion bugs and expands epoch-arithmetic test coverage.
• Significantly faster Map reads and writes. The read path avoids materializing an intermediate pair tuple, with the win scaling with entries per row. The write path moves into a new Cython build_map_columns helper.
• Order-of-magnitude faster fixed-width numeric inserts from numpy arrays, with significantly lower peak memory. A new Cython write_native_col helper writes 1-D C-contiguous numpy arrays of matching dtype directly into the output buffer via memcpy, avoiding the per-element conversion the previous path required.
• Significantly faster Decimal and BigDecimal reads. The decode path no longer constructs intermediate strings per row, building values directly from the integer column via Decimal.scaleb.

Bug Fixes

• Async client: retry once when a pooled keep-alive connection is closed by the server and aiohttp raises ServerDisconnectedError with the default "Server disconnected" message. The existing retry path covered "Connection reset" and "Remote end closed", but not the bare ServerDisconnectedError() produced by recent aiohttp versions, which surfaced as an OperationalError("Network Error: Server disconnected") on the first request after an idle period.
• SQLAlchemy Bool type now accepts and forwards **kwargs to the underlying SqlaBoolean constructor. SQLAlchemy's SchemaType machinery passes internal kwargs (e.g., _create_events) when copying or adapting the type during ORM model use or Table.to_metadata(), which previously raised a TypeError. Fixes #705
• SQLAlchemy: CreateDatabase with engine="Replicated" now emits a closing ) after the (zoo_path, shard, replica) arguments, fixing previously invalid DDL on this path. The same arguments and the system.tables lookup in get_engine now go through bound parameters and the existing format_str helper instead of raw f-string interpolation.

1.0.0rc1, 2026-04-22

Breaking Changes

• Dropped the pytz dependency in favor of the standard library zoneinfo. On Windows, tzdata is pulled in automatically. On slim Linux containers without a system tzdb, install pip install clickhouse-connect[tzdata].
• Unknown timezone strings from query_tz, column_tzs, or the server now surface zoneinfo.ZoneInfoNotFoundError internally (previously pytz.exceptions.UnknownTimeZoneError). User-visible ProgrammingError/log messages suggest the tzdata extra. Closes #714.
• Remove the legacy executor-based async client. The AsyncClient(client=...) constructor pattern, executor_threads, and executor parameters are no longer supported. Use clickhouse_connect.get_async_client() (or create_async_client()) which creates a native aiohttp-based async client directly. The pool_mgr parameter is also rejected on the async path. aiohttp remains an optional dependency, installed via pip install clickhouse-connect[async].
• The internal AiohttpAsyncClient class has been renamed to AsyncClient and the module clickhouse_connect.driver.aiohttp_client has been removed. Import AsyncClient from clickhouse_connect.driver as before.
• Removed the deprecated utc_tz_aware parameter entirely. Use tz_mode instead: "naive_utc" (default, was False), "aware" (was True), or "schema" (unchanged). Closes #654, #665
• Removed the deprecated apply_server_timezone parameter entirely. Use tz_source instead: "auto" (default), "server" (was True), or "local" (was False).
• Dropped pandas 1.x support. Minimum pandas version is now 2.0. Users with pandas < 2.0 will get a NotSupportedError at import time. Non-pandas usage is unaffected. Closes #661
• Removed the preserve_pandas_datetime_resolution common setting. Datetime columns now always return their natural resolution, e.g. datetime64[s] for DateTime, datetime64[ms] for DateTime64(3), instead of coercing everything to datetime64[ns]. Closes #662
• Dropped Python 3.9 support. The minimum supported Python version is now 3.10. 0.15.x is the last series supporting Python 3.9.

Bug Fixes

• Fix Dynamic/JSON column reads when a path's inferred type sorts alphabetically after "SharedVariant". ClickHouse's DataTypeVariant constructor sorts its members alphabetically by name, and discriminator bytes on the wire index into that sorted order. The client appended SharedVariant to the variant list without sorting, so affected paths were read as the wrong variant. Closes #712
• Fix async streaming race condition that caused unhandled InvalidStateError exceptions on early stream termination. When breaking out of an async stream early, shutdown() scheduled a set_result callback for pending futures via call_soon_threadsafe, but Task.cancel() could cancel the future before the callback ran. The done-check is now deferred into the callback itself so it sees the actual future state at execution time.
• SQLAlchemy: Wrap raw SQL strings in text() in ChClickHouseDialect.get_schema_names() and get_table_names(), so Inspector.get_schema_names() and get_table_names() work on SQLAlchemy 2.x instead of raising ObjectNotExecutableError.
