Is there API in Java dataset that describe the status of newly created index

[yuqi1129]

As we are going to implement a custom Lance REST service, I wonder if there exists an API in the Java dataset that can get status of an index(see: https://lancedb.github.io/lance/format/namespace/operations/describe-table-index-stats/). There seems to be no such method currently.

that's cool!

You should probably look at https://www.javadoc.io/doc/com.lancedb/lance-core/0.39.0/index.html. (seems like Dataset can list indexes, but not get details of a single one, which we might need to add a binding for...)

The Lance Namespace spec does define a DescribeTableIndex feature, but it is not fully implemented yet in the SDKs. So far we have been focusing on just the basic operations.

I agree that some kind of "describe index" function would be a good spot for this. I'm adding describe_indexes to rust here: #5221

There is no concept of status of course since it doesn't make sense for the embedded rust engine but I think it could help inform the describe index REST API.

Good work, I'm looking forward to it.

I see.
