<!here> As we made several enhancements and optimizations to the star-tree index (learn more about star-tree here: https://pinot.readthedocs.io/en/latest/star-tree/star-tree.html), we plan to remove the support of the old star-tree index. If you have use cases with the old star-tree index (generated with

StarTreeIndexSpec

), please let us know and we can figure out a way to migrate it to the new one.

To migrate do we use the StarTreeIndexConfig like the example in star-tree.html? Currently we do use StarTreeIndexSpec
