> Ensure unique timestamps are generated for commit times with concurrent
> writers.
> this is the piece of code in HoodieActiveTimeline which creates a new commit
> time.
> {code:java}
> public static String createNewInstantTime(long milliseconds) {
> return lastInstantTime.updateAndGet((oldVal) -> {
> String newCommitTime;
> do {
> newCommitTime = HoodieActiveTimeline.COMMIT_FORMATTER.format(new
> Date(System.currentTimeMillis() + milliseconds));
> } while (HoodieTimeline.compareTimestamps(newCommitTime,
> LESSER_THAN_OR_EQUALS, oldVal));
> return newCommitTime;
> });
> }
> {code}
> There are chances that a deltastreamer and a concurrent spark ds writer gets
> same timestamp and one of them fails.
