[jira] [Updated] (HIVE-17987) Certain metastore operation should use iterators of partitions over lists

     [ https://issues.apache.org/jira/browse/HIVE-17987?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Adam Szita updated HIVE-17987:
------------------------------
    Description: In HS2 side we have a PartitionIterable class to reduce memory load and use iterators of partitions instead of whole lists when querying them from HMS. Inside HMS there is no such feature and we should create a similar one. (e.g alter table calls that have to apply a modification to each and every partition of the table)
