We're excited to announce the release of ClickHouse, Inc., our first release since announcing our company. This release includes new contributions from multiple contributors and is a result of the ongoing ideas, development, and support from our community. Our engineering team has been focused on providing the fastest and most scalable OLAP DBMS available while implementing many new features. The 21.10 release highlights exciting new capabilities, including user-defined functions as lambda expressions, two new table engines for streaming query results to custom scripts, and improved logging capabilities. Additionally, positional arguments are now available in GROUP BY, ORDER BY, and LIMIT BY clauses, making queries more efficient. We're grateful for the contributions of our community members and welcome new contributors to join us.
