Hi, Is there anything in parquet right now that would allow me to efficiently subselect a set of rows from a file given a list of integer row indices? In my particular case, I'm only interested in flat tables and not additional hierarchy. Primarily what I would like to avoid is holding a large number of rows in memory only to immediately discard them; and, also, for very sparse subsets of rows avoid reading/decompressing row groups without any of the rows I need.
