[jira] [Created] (ASTERIXDB-3433) Number of cloud read requests could be excessive

Ritik Raj created ASTERIXDB-3433:
------------------------------------

             Summary: Number of cloud read requests could be excessive
                 Key: ASTERIXDB-3433
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-3433
             Project: Apache AsterixDB
          Issue Type: Bug
          Components: STO - Storage
    Affects Versions: 0.9.10
            Reporter: Ritik Raj


Reading columnar mega pages that are not contiguous could be slowed by the number of requests as each range of contiguous pages will requested separately. In fact, doing SELECT * can be 2x faster than doing SELECT c1, c2, ..., cN  (where N is a double digit number) if each column initiate a cloud read request 

Such requests should be capped to a small number.
