HTTP temporary buffers in ClickHouse now support eviction of data from the virtual filesystem cache to better manage memory usage.
Why it matters
This feature addresses the problem of excessive memory consumption caused by HTTP temporary buffers holding data in the virtual filesystem cache. By enabling eviction, it allows more efficient memory management and reduces cache pressure, improving overall system performance and stability.How to use it
The HTTP temporary buffer feature with virtual filesystem cache eviction works internally and does not require explicit user action to enable. Users benefit from improved memory handling when using HTTP temporary buffers in ClickHouse.
