(Updated Jan. 26, 2017, 2:58 p.m.) Review request for atlas and David Kantor. Changes ------- Addressed review comments. Repository: atlas Description ------- Apply performance fixes for create/update entities from IBM fork to Atlas. During our performance profiling, we found a number of performance hotspots in JProfiler. Our main findings were - multiple queries were being executed for each instance being created/updated to find matches by unique attribute. - one query was being executed for each instance being created/updated to find the corresponding vertex if there is one - Calculating the value of the full text property was taking a significant portion of the time to create/update entities, mainly due to its calls to getVertexForGUID The changes we put in do the following: - batch lookups by guid when create/update entities. Execute one AtlasGraphQuery to find them all. - batch lookups by unique attribute when create/update entities. Execute one AtlasGraphQuery per class to find unique attribute matches. - find all existing vertices up front during create/update entity. Use those vertices during the graph mapping process to avoid running unnecessary graph queries - reuse reference vertices from instance to graph mapping when computing full text property Also, resolved all test failures in webapp. I disentagled the three competing versions of the hive model that the various tests were trying to use. Now they all pass. I tried to follow the path of least resistence. We really should clean this up more, there is really no need for threee different versions of hive_table and its related classes.
