-----------------------------------------
Summary: Reduce I/O when loading objects into NATable and
NARoutine cache
Key: TRAFODION-2327
URL: https://issues.apache.org/jira/browse/TRAFODION-2327
Project: Apache Trafodion
Issue Type: Improvement
Components: sql-cmp, sql-security
Reporter: Roberta Marton
Assignee: Roberta Marton
This is a request to reduce the number of I/O's performed when objects are
loaded into caches. Today, the list of roles is read from Metadata every time
any object is placed into NATable and NARoutine cache. Since the list of roles
associated with the current user is the same independent of the object being
referenced, redundant I/O's are performed. The list of roles does change
whenever a grant or revoke role is performed against the user, so the solution
must make sure grant and revoke operations are handled correctly.
