Why it matters
This feature introduces the ability to run queries in parallel across replicas, improving query performance and resource utilization in distributed setups by leveraging multiple replicas simultaneously. It solves the problem of underutilization of replicas in replicated environments and enhances efficiency in query execution.How to use it
To enable the experimental parallel replicas feature, users need to configure the relevant settings as described in the pull request documentation. This typically involves enabling the experimental feature flags and adjusting settings related to query execution on replicas.
