> Existing bootstrap code lists all files in the dataset and caches a FileStatus object for each file found. FileStatus object has many fields which take memory and most of these fields are not even used later as part of bootstrap.
> For a very large production table, the bootstrap code fails with OOM and also leads to timeout as a very large number of executors are spawned.
> Dataset has 1299 partitions and 12Million files.
