• Expose latency and per target stats globally
• Docs ticket for latency and perTarget stats
• Remove avgTimeSpent
• confirm if the below is needed:

• • Feature flag to adjust number of targets supported
  • Warn if number of targets exceeds the threshold.
  • We might want to put the information in the checkpoint summary stats which survive stream processor modifications. We can make a follow up ticket for this and discuss with PMs on the desired behavior.

Make backlog ticket for:

• remove toAdditiveStats
• Avoid the tdigest copy in Summary copy and copy assignment operators
• Avoid the loop in SourceOperator
• More tests
  • test unwind case
