Stream chunks in system.filesystem_cache table instead
Stream chunks in system.filesystem_cache table instead of creating a single chunk with all cache state. Reading filesystem cache state can take a long time for large caches and consume a lot of memory, so streaming it is indispensable for large deployments. #90508 (Kseniia Sumarokova).Why it matters
Reading the full filesystem cache state can be time-consuming and memory-intensive for large caches. Streaming chunks improves performance and reduces memory usage, which is essential for large-scale deployments.How to use it
The feature is applied automatically when querying thesystem.filesystem_cache table, where the cache state is now streamed in multiple chunks instead of one large chunk.
