Alexey Kudinkin updated HUDI-5556:
----------------------------------
    Description: 
Currently, most of the HoodieTableMetadata APIs (getColumnStats, 
getBloomFilters, etc) provide only for loading the data from MT in-memory which 
shifts the burden on the caller to break their requests in chunks to make sure 
these fit in memory: for ex, trying to read Bloom Filters from MT, Bloom Index 
(caller) have to make sure we're not reading more than 256 filters at a time to 
limit its memory footprint.

 

Instead HoodieTableMetadata API has to be
 # Rebased to rely on HoodieData
 # Provide levers to the caller whether MT should be read in-memory or 
on-cluster
 #
