RisingWave does allow disaggregation of compute resources for different needs, such as pinning compute nodes to do stream processing, serving, etc. However, it currently does not support sharing namespaces or schemas across multiple clusters. A typical setup might involve separate clusters for production, staging, and development, with the ability to disaggregate compute nodes within a single cluster to prevent workloads from interfering with each other. While there is no current feature to disaggregate further within stream processing, it is technically feasible that a future RisingWave product could allow grouping of nodes in the cluster and assigning queries to a group, similar to Materialize's clusters. This is not a firm limitation of RisingWave for the medium to long term future.
