[I] [Umbrella][Flink] Improve Fluss Flink Connector production readiness [fluss]
loserwang1024 opened a new issue, #3721:
URL: https://github.com/apache/fluss/issues/3721
### Search before asking
- [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar.
### Motivation
The Fluss Flink Connector has already provided many important capabilities for building real-time analytics and lakehouse pipelines with Flink, including streaming reads, lookup joins, sink writes, changelog consumption, and integration with Fluss tables.
However, there are still several limitations that make it harder to adopt Fluss in production workloads, especially compared with more mature connectors. For example, batch reading is still limited, virtual tables do not yet have the same capabilities as normal tables, lookup joins lack full-cache support, source and lookup metrics are not complete enough for production troubleshooting, and batch DML/write optimizations still need improvement.
This umbrella issue tracks the work planned in this release to improve the completeness, performance, and operability of the Fluss Flink Connector.
After this umbrella issue is completed, the Fluss Flink Connector should be more complete and production-ready for real-time analytics, real-time lakehouse, lookup join, historical replay, and batch maintenance workloads.

@loserwang1024 do we have a list? I think there are already a few tickets hanging around related to this umbrella, and I will attach them.
Happy to help with this effort

Thanks for putting together this umbrella issue — it captures the gaps really well.
I already opened #3670 (custom lookup shuffle) which fits here. I'd also like to take on the batch reading and virtual tables items — feel free to assign them to me.
