-----------------------------------------
Summary: Eliminate needless synchronization in java-R serialization
Key: SPARK-21575
URL: https://issues.apache.org/jira/browse/SPARK-21575
Project: Spark
Issue Type: Improvement
Components: SparkR
Affects Versions: 2.2.0
Reporter: Iurii Antykhovych
Priority: Trivial
As long as {{org.apache.spark.api.r.JVMObjectTracker}} is backed by
{{ConcurrentHashMap}}, synchronized blocks in {{get(..)}} and {{remove(..)}}
methods can be safely removed.
This would eliminate lock contention in {{org.apache.spark.api.r.SerDe}}
and {{org.apache.spark.api.r.RBackendHandler}}.
