Parquet - Inline Indices

Hi:

What's the latest on support for inline indices for columns in a parquet file? Is this supported in 1.5 or 1.6.0.rcX and what limitations exists around predicate pushdown (i.e. for analytical toolkits that can leverage this, what are the limitations in Parquet itself that constrain how this gets surfaced?) for e.g there was a reference to an issue about this not functioning yet for columns that were optional. Thanks!
