TINKERPOP-1676 (master) GraphSON Performance https://issues.apache.org/jira/browse/TINKERPOP-1676 Had to do a separate PR for this as we've made changes in testing IO on master - see #613 for more details on what this PR is about. Running the full build now - will edit this PR when it's done successfully.

Will it ever all be gone from these performance sensitive places?! Anyway, removed that and deprecated a constructor on DetachedEdge that was using Pair for no really good reason. No need to create extra Pair objects for that. They just sorta get thrown away after usage. commit 251f5b7e34e8ebd9a8bc36802e633be8c91eeb5e Author: Stephen Mallette <sp...@genoprime.com> Date: 2017-05-23T20:57:12Z TINKERPOP-1676 Improved speed and memory usage of GraphSON This change is specific to TinkerGraph and the serialization of vertices/edges/properties. Removed a "middle layer" of JSON to Object serialization which was coercing JSON to Map first and then converting that to the graph elements. Also made deserializers cacheable. commit 02b007366b434918fe1181f99d80689c1c03684b Author: Stephen Mallette <sp...@genoprime.com> Date: 2017-05-24T00:13:46Z TINKERPOP-1676 Performance enhancement to graphson serialization Focuses on speeding up serialization of graph elements. Prevent use of generic maps and stream graphson data directly into "detached" elements. Not using intermediate maps cut down on memory usage and a bunch of jackson reflection calls (still not sure what they were for and why they were not made to be more efficient). It did mean some ugly changes to "detached" stuff. Will need to maybe refactor some more, but the basic premise seems to be proven. commit e5d2d2bc000654fd026521219cf30bac265139a3 Author: Stephen Mallette <sp...@genoprime.com> Date: 2017-05-24T17:38:16Z TINKERPOP-1676 Removed properties from graphson serialization of Path Path should not have properties on elements (if they are present). That is inconsistent with gryo and was unintentially allowed. commit 049c979720a84ea9744725fda5f8d2b371ab1751 Author: Stephen Mallette <sp...@genoprime.com> Date: 2017-05-25T17:29:45Z TINKERPOP-1676 More optimizations to GraphSON serializers Added some tests where there were previously gaps. commit f32d725a080d39ef7bf93c68d8080939f622cb37 Author: Stephen Mallette <sp...@genoprime.com> Date: 2017-05-25T18:03:29Z TINKERPOP-1676 Cleaned up serialization with detached The DetachedUtil was just there to test out if the performance changes would help and it did it's job nicely, but it was kinda ugly and hung some methods out there in weird way. Cleaned that up with some builder pattern on the detached classes themselves. commit bb7ff8290962e30dd4d78c4bd904eef31a3f2478 Author: Stephen Mallette <sp...@genoprime.com> Date: 2017-05-25T19:25:32Z Merge branch 'TINKERPOP-1676' into TINKERPOP-1676-master Conflicts: docs/src/dev/io/graphson.asciidoc ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
