--------------------------------------------
Summary: Race condition in Tinkergraph index creation
Key: TINKERPOP-1830
URL: https://issues.apache.org/jira/browse/TINKERPOP-1830
Project: TinkerPop
Issue Type: Bug
Components: tinkergraph
Affects Versions: 3.2.6, 3.3.0
Reporter: Michael Pollmeier
Priority: Minor
Fix For: 3.2.7, 3.3.1
My colleage Fabian Yamaguchi <[email protected]> discovered a race condition in
tinkergraph's index creation. He fixed it by simply replacing `parallelStream`
with `stream`. Quoting his analysis:
> So, reading the code, you see that this.put is called in parallel, but that
> method seems to contain a race as get is called on the index, checked for
> null, and a subsequent write is performed. It still seems like using stream
> here fixes the problem we've been seeing, and the performance hit is not
> significant.
