repository/src/main/java/org/apache/atlas/discovery/EntityDiscoveryService.java Line 120 (original), 142 (patched) <https://reviews.apache.org/r/73128/#comment311541> - for readability, and to be consistent with rest of Atlas sources, please move private methods after all public methods - given this is a oneliner, and called only once from the constructor, is there a need for a separate method? repository/src/main/java/org/apache/atlas/query/AtlasDSL.java Lines 153 (patched) <https://reviews.apache.org/r/73128/#comment311542> - per earlier comment, why not final for resolvedLimit and resolvedOffset as well? - suggest to rename as: resolvedLimit => limit resolvedOffset => offset repository/src/main/java/org/apache/atlas/query/GremlinQueryComposer.java Line 88 (original), 92 (patched) <https://reviews.apache.org/r/73128/#comment311543> - context is not initialized here. It should be, perhaps with: this.context = new Context(lookup); - also, mark this.context as final - Madhan Neethiraj On Jan. 13, 2021, 8:26 p.m., Ashutosh Mestry wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
