## Summary of Changes
Hello @arunpandianp, I'm Gemini Code Assist[^1]! I'm currently reviewing
this pull request and will post my feedback shortly. In the meantime, here's a
summary to help you and other reviewers quickly get up to speed!
This pull request is a work in progress, marked as 'NOT FOR MERGE', and
focuses on implementing a new version of Windmill tag encoding (V2) for Apache
Beam's Dataflow runner. The primary goal of this new encoding is to establish a
specific lexicographical order for state and timer tags, which is essential for
optimizing range-based queries. The changes involve core API modifications, the
introduction of the new encoding logic, and updates to the Dataflow worker to
allow conditional activation of this feature through an experiment flag.
### Highlights
* **New Windmill Tag Encoding (V2)**: Introduced `WindmillTagEncodingV2` to
provide a new, lexicographically ordered encoding scheme for state and timer
tags in Apache Beam's Dataflow runner. This new encoding facilitates efficient
range filtering of tags.
* **Conditional Activation via Experiment Flag**: The
`WindmillTagEncodingV2` can be enabled in the Dataflow worker via an
`unstable_windmill_tag_encoding_v2` experiment flag, allowing for controlled
rollout and testing of the new encoding.
* **API Updates for Tag Encoding**: Modified `StateNamespaces`, `StateTags`,
and `WindmillTagEncoding` interfaces/classes to support the new encoding,
including adding methods to retrieve window coders and check for system tags,
and updating the `timerHoldTag` signature.
* **Comprehensive Testing**: Added a dedicated test suite
(`WindmillTagEncodingV2Test`) to thoroughly validate the encoding and decoding
logic, as well as the enforced lexicographical sort order for various tag types
and namespaces.
🧠**New Feature in Public Preview:** You can now enable **Memory** to help
**Gemini Code Assist** learn from your team's feedback. This makes future code
reviews more consistent and personalized to your project's style. **Click
