important hint
PageCache and ChunkAllocator are disabled by default to reduce memory usage, and users can re-enable them by modifying configuration items disable_storage_page_cacheand . chunk_reserved_bytes_limitStorage Page Cache and Chunk Allocator cache user data blocks and memory preallocation respectively. These two functions will occupy a certain percentage of memory and will not be released. This part of the memory usage cannot be flexibly allocated, resulting in insufficient memory for other tasks due to this part of the memory usage in some scenarios, affecting system stability and availability. So we turned off these two features by default in version 1.1.3. However, in some latency-sensitive reporting scenarios, disabling this feature may increase query latency. If the user is concerned about the impact of this function on the business after the upgrade, the following parameters can be added to be.conf to keep the behavior consistent with the previous version.
disable_storage_page_cache=false
chunk_reserved_bytes_limit=10%
disable_storage_page_cache: Whether to close Storage Page Cache. Versions before 1.1.2 (inclusive), the default is false, that is, open. Version 1.1.3 defaults to true, which is closed.
chunk_reserved_bytes_limit: Chunk Allocator reserved memory size. For versions before 1.1.2 (inclusive), the default is 10% of the overall memory. Version 1.1.3 defaults to 209715200 (200MB).
