ClickHouse Newsletter June 2022: Materialized, but still real-time

ClickHouse has released a new version v22.6, which includes features such as memory overcommit, parallel hash joins, and grouping sets. The release also addresses performance issues with querying incomplete time series data by introducing materialized views that can pre-aggregate recent values while still allowing for real-time queries. This approach combines the benefits of materialized views with the flexibility of querying raw data.
