Introduces non-blocking loading for external dictionaries in ClickHouse, allowing dictionaries to load asynchronously without blocking query execution.
Why it matters
This feature solves the issue of query delays caused by synchronous dictionary loading. It enhances system responsiveness and availability by enabling dictionary data to be loaded in the background, thus improving performance and user experience.How to use it
Users can enable non-blocking loading by configuring their external dictionaries accordingly. This typically involves setting the dictionary loading parameters to allow asynchronous updates, so dictionaries load without blocking queries.
