   Compatibility question before we retain any vector-specific freshness 
machinery: @cvinoth, is the release/table format carrying the vector index 
intended to require a table-version bump that fences older writers? Current 
master routes configured/inflight metadata partition paths through 
MetadataPartitionType.fromPartitionPath, which rejects unknown vector_index_* 
paths, so an older writer that observes the partition fails closed. We have not 
yet established the behavior of a pre-existing writer with cached pre-index 
table configuration. We want to reuse Hudi RLI/SI compatibility semantics 
rather than add a per-commit frontier for a writer that is already fenced. 
Could you confirm the intended writer compatibility/table-version contract?
