Can we use an Enum to specify which version to use? We will likely to have new index format down the road.

I initially thought of doing that and just pass the LanceVersion, however, I was not sure how does it tie to the index builder. Can change it to the lance version if that makes it clearer

+1. I would prefer a index_file_version parameter over a use_new_index_format flag.

there are V1 and V3 if you are going to create that enum
V2 has been removed, no index is in V2 format now.

@BubbleCal @westonpace Wanted to see if there are any other review comments that I need to address apart from the enum change that @eddyxu suggested |

Instead of making separate test functions, could we parametrize the test functions with rstest?

I just added |
PR adds the ability to create v3 ivf_pq indices from python by passing in a bool parameter via the VectorIndexParams python. Right now it just sets the value to true for IVF_PQ but it can be used for other indices as well. Also, it doesn't change the JNI side for IVF_PQ for now, but can be added as a follow-up PR.
Added a bunch of tests in python and rust to test this.
