swuferhong opened a new issue, #10:
URL: https://github.com/apache/fluss-shaded/issues/10
**Description**:
Fluss depends on fluss-shaded-arrow which currently bundles Arrow Java
15.0.0. We need to upgrade to 19.0.0 to gain access to the Variant type support
introduced in newer Arrow releases, which Fluss will rely on for its Variant
data type implementation.
**Motivation**
Apache Arrow 19.0.0 introduced the Variant logical type (a self-describing,
semi-structured data format). Fluss needs this type to support Variant columns
in its storage and compute layers.
**Notes**
This is a 4-major-version jump. Key areas to watch:
- Memory allocator API changes (BufferAllocator)
- Vector API deprecations/removals
- Flatbuffers dependency version bump
- IPC format compatibility (if applicable)
