ClickHouse v21.11 Released

The ClickHouse team has released version 21.11, which includes several exciting new capabilities such as asynchronous inserts, interactive mode, UDFs, predefined connections, and compression gains. Asynchronous inserts allow for high rates of small inserts to be concurrently processed, reducing the need for large batches and improving performance. Local interactive mode enables users to run ClickHouse queries on local files without connecting to a server, making it ideal for ad-hoc use cases. Executable UDFs enable users to write custom functions in any programming language, while predefined connections simplify data source connections by allowing users to reference external data sources by name. Additionally, compression support has been added for importing and exporting data into ClickHouse. These new features aim to improve performance, user experience, and productivity for ClickHouse users.
