----------------------------
Summary: Improve performance of incrementally updating policies
Key: RANGER-2879
URL: https://issues.apache.org/jira/browse/RANGER-2879
Project: Ranger
Issue Type: Bug
Components: plugins
Affects Versions: 2.0.0
Reporter: star
Assignee: star
There is large amount of deleting policy operation in incrementally updating
mechanism. But policies in RangerPolicyRepository is a List<RangerPolicy>.
{code:java}
//
private void removePolicy(Long id) {
if (LOG.isDebugEnabled()) {
LOG.debug("==> RangerPolicyRepository.removePolicy(" + id +")");
}
Iterator<RangerPolicy> iterator = policies.iterator();
while (iterator.hasNext()) {
if (id.equals(iterator.next().getId())) {
iterator.remove();
break;
}
}
policyEvaluatorsMap.remove(id);
if (LOG.isDebugEnabled()) {
LOG.debug("<== RangerPolicyRepository.removePolicy(" + id +")");
}
}
{code}
Replace list with a map structure will improve performance of removePolicy a
lot.
