--------------------------------------
Summary: Support multiple threads to build Trie and on-lookup
post-setup for Trie nodes
Key: RANGER-2188
URL: https://issues.apache.org/jira/browse/RANGER-2188
Project: Ranger
Issue Type: Bug
Components: Ranger
Affects Versions: master
Reporter: Abhay Kulkarni
Assignee: Abhay Kulkarni
Fix For: master
Time for building a Trie index for resources may become a bottleneck when
dealing with large number of resources. It is desirable to build different,
non-overlapping parts of Trie structure using multiple threads to reduce
overall build time if configured to do so.
Also, instead of building out all Trie nodes completely (that is, by
propagating wildcard evaluators all the way to all leaves of Trie tree) at the
initialization time, it is optimal to do so as a Trie-Node is accessed for the
first time during resource lookup.
