There was a problem hiding this comment.
Maybe just fields.title_embedding.dimension.

Purpose
Support per-field vector index options with
fields.<field-name>.<option>.This allows tables with multiple vector columns using the same index type to configure different dimensions or index parameters for each column. Field-level options do not include the index-type prefix, and they override index-type-level defaults such as
<index-type>.<option>for the matching stored table column name.Tests
Added unit tests in
VectorGlobalIndexerFactoryTest:fields.<field-name>.*optionsAlso ran:
git diff --checkmvn -o -pl paimon-vector/paimon-vector-index -Pfast-build -Dtest=VectorGlobalIndexerFactoryTest testfailed locally becauseorg.apache.paimon:paimon-core:jar:tests:1.5-SNAPSHOTwas not available in the local Maven cache.
