The recursive data.path FilePermission check is an extremely hot codepath in Elasticsearch. Unfortunately the FilePermission check in Java is extremely allocation heavy. As it iterates through different file permissions, it allocates byte arrays for each Path component that must be compared. This PR improves the situation by adding the recursive data.path FilePermission it its own PermissionsCollection object which is checked first. |
