      Description

      Joep Rottinghuis brought up an interesting point in YARN-3411. Filing jira to track to discuss and handle the following:

      For TimelineWriter and its implementations, is there an expectation set around
      concurrency? Is any synchronization expected / needed to ensure visibility when calls happen from different threads?
      How about entities, are they expected to be immutable once passed to the write method?
      Similarly for the constructor, we're assuming that the configuration object will not be modified while we're constructing a TimelineWriter?
