warningThreshold
- how far in the future timestamps are allowed to drift before a warning
is logged.warningThresholdUnit
- the unit for warningThreshold
.warningInterval
- how often the warning will be logged if timestamps keep drifting above
the threshold.warningIntervalUnit
- the unit for warningIntervalUnit

TimestampGenerator
Implementors should enforce increasing monotonicity of timestamps, that is, a timestamp returned should always be strictly greater that any previously returned timestamp.
Implementors should strive to achieve microsecond precision in the best possible way, which is usually largely dependent on the underlying operating system's capabilities.

sent by the driver, letting Cassandra generate a server-side timestamp.Copyright © 2012–2019. All rights reserved.
