+`ForStStateBackend` utilizes [ForSt](https://github.com/ververica/ForSt/) as
its underlying database core.
+The current iteration of ForSt is forked from
[frocksdb](https://github.com/ververica/frocksdb),
+architected as an embedded database core specifically for Flink local state
management.
+
+While transitioning the db toward a disaggregated architecture, we encountered
significant
+architectural and engineering constraints within the existing framework.
+To address these challenges, we are now actively developing a next-generation,
+cloud-native ForSt DB written in Rust.
+
+#### Key Advantages of the New ForSt DB:
+- Architectural Simplicity: A streamlined codebase designed for high
extensibility.
+- Stream-Native Design: Optimized specifically for the unique demands of
large-scale stream processing.
+- Cloud-Native: Built from the ground up to support disaggregation.
Review Comment:
I think that's a bit early at this point as it has not been released/open
sourced. We do not want to make any commitments here so we should try to keep
this somewhat vague in order not to mislead anyone or set very high
expectations.
