Company Overview
About ClickHouse Cloud
ClickHouse Cloud is the fully managed cloud service built on ClickHouse, the open-source columnar database originally developed at Yandex and now one of the fastest-growing analytical databases in the world. ClickHouse's column-oriented storage format and vectorized query execution engine are engineered for analytical queries over billions of rows, routinely delivering sub-second response times on aggregation and filtering workloads that would take minutes in traditional row-oriented databases. The cloud service abstracts infrastructure management — provisioning, scaling, backups, and upgrades — while preserving full compatibility with the open-source ClickHouse interface and SQL dialect.
Business Model & Competitive Advantage
The platform is purpose-built for observability, product analytics, time-series analysis, and log management use cases where query latency directly impacts user experience. ClickHouse Cloud supports elastic scaling that adjusts compute resources based on query demand, enabling cost-efficient operation for workloads with variable query volumes. Its shared-nothing distributed architecture allows horizontal scaling to handle growing data volumes, and its native support for semi-structured data types makes it well-suited for event and log data that does not fit neatly into a fixed schema.
Competitive Landscape 2025–2026
ClickHouse Cloud targets engineering and data teams at technology companies building real-time analytics products, observability platforms, and user-facing dashboards where query speed at scale is a hard requirement. The company competes with Snowflake, BigQuery, and purpose-built observability databases like Splunk and Elasticsearch, differentiating through raw query performance and cost efficiency at high data volumes. ClickHouse Inc. has raised over $300M in funding and has accumulated a large open-source community of tens of thousands of deployments worldwide that feeds commercial adoption of the cloud offering.

## Bug Fixes - Use timezone from parameter type hint instead of `server_tz` when formatting tz-aware datetimes in `{param:Type}` bind expressions. Fixes #697
# Improvements - Comprehensive ClickHouse `JOIN` support in SQLAlchemy via `ch_join()` with all strictness/distribution modifiers and `USING` syntax (#635, #636) - Multi-column `array_join()` for parallel array expansion (#633) - Add missing Replicated engine variants (`ReplicatedReplacingMergeTree`, etc.) (#687) - Lazy imports for `numpy`, `pandas`, `pyarrow`, and `polars`, ~4x faster bare import time (#589) # Bug Fixes - Fix `.final()` and `.sample()` silently overwriting each other when chained (#658) - Fix `sqlalchemy.values()` to emit ClickHouse `VALUES` table function syntax (#681) - Fix `GraphiteMergeTree` to properly quote `config_section` argument # Other - Remove `py.typed` marker that was causing false type errors for mypy/pyright users (#691) **Full Changelog**: https://github.com/ClickHouse/clickhouse-connect/compare/v0.14.1...v0.15.0
### Improvements - **[client-v2]** Added `Records#getSchema()` to expose table schema metadata even when query result is empty. (https://github.com/ClickHouse/clickhouse-java/pull/2777) ### Bug Fixes - **[jdbc-v1, jdbc-v2]** Fixed type mapping/conversion behavior for large unsigned integer values (issue #2779), including related test coverage updates. (https://github.com/ClickHouse/clickhouse-java/issues/2779) - **[jdbc-v2]** Fixed off-by-one bug in `ArrayResultSet#next()` that could return `true` one extra time and then fail with `SQLException: No current row`. (https://github.com/ClickHouse/clickhouse-java/pull/2790) - **[jdbc-v2]** Fixed handling of malformed `SELECT`-like queries (for example, `SELECT a, FROM table`): previously, the driver could fail to read returned data when query type was not inferred before execution; now it detects a returned result set at runtime from the server response and reads it correctly. (https://github.com/ClickHouse/clickhouse-java/issues/2784) ###
## Bug fixes - Fixed JSON and Dynamic column read paths to properly decode shared variant data instead of returning raw binary with discriminator byte prefixes. Closes #599, #615, #674 - Fixed empty ORM/DBAPI `SELECT` results so `cursor.description` is still populated when ClickHouse Native format returns no data blocks. This restores correct handling for empty result sets, including parameterized and limited queries. Closes #675 - Reenabled the default Cython runtime path so compiled driverc modules are used again unless `CLICKHOUSE_CONNECT_USE_C=0` is exoplicitly set. Closes #676 **Full Changelog**: https://github.com/ClickHouse/clickhouse-connect/compare/v0.14.0...v0.14.1
## High level notes This release is primarily focused on preparing the path to 1.0.0. It introduces a handful of breaking changes and deprecation warnings for APIs that will be removed or finalized in 1.0.0. If your code uses any of the deprecated parameters, you'll now see `DeprecationWarning`s with clear migration guidance and highly recommend addressing these before upgrading to 1.0.0 when it ships. ## Breaking Changes - `apply_server_timezone` renamed to `tz_source`. Options are `"auto"` (the default), `"server"`, or `"local"`. The old parameter currently still works with a deprecation warning. https://github.com/ClickHouse/clickhouse-connect/pull/670 - `utc_tz_aware` renamed to `tz_mode`. Options are `"naive_utc"` (the default), `"aware"`, or `"schema"`. The old parameter still currently still works with a deprecation warning. https://github.com/ClickHouse/clickhouse-connect/pull/664 - Removed `Object('json')` type. This was a legacy experimental JSON type has been removed in favo
