Description
Please add this as a warning in the analytics documentation pages:
Configuring Non-Uniform Memory Access (NUMA) can significantly impact the performance and stability of Couchbase Analytics Service. NUMA architectures divide memory into different zones, each with a specific CPU, and accessing memory across zones can lead to latency. Couchbase Analytics is not configured to align with the NUMA architecture, it may result in uneven memory distribution, increased latency, and degraded performance. Specifically, queries can become slower, and overall system efficiency can drop as memory access times vary significantly.
This may affect all versions of couchbase.
