Class IndexUtils

java.lang.Object
io.fluxcapacitor.javaclient.tracking.IndexUtils
public class IndexUtils extends Object
Use 48 bits of the current time in milliseconds since epoch as the base of the index. The remaining 16 bits (65k) are used to increment the index if messages are written in the same ms as the last batch.

The index is only able to store 2^47 - 1 ms of time since epoch, i.e. about 4,500 years.

Uses FluxCapacitor.currentClock() to get the index corresponding to the current timestamp of Flux Capacitor's internal clock.
