Field Detail

TIME_UUID_COMPARATOR

public static final Comparator<MetricData> TIME_UUID_COMPARATOR

timeUUID

protected UUID timeUUID

metric

protected Metric metric

tags

protected Set<Tag> tags

writeTime

protected Long writeTime

ttl

protected Integer ttl

This is only used in calculating an updated TTL for data that has already been inserted. It might make more sense to move this field closer to where the computations are performed and used.
