FlakeIdGenerator.newId()
is made. Default is 100.
This setting pertains only to newId
calls made on the member
that configured it.

prefetchCount
- the desired prefetch count, in the range 1..100,000.public FlakeIdGeneratorConfig setPrefetchValidityMillis(long prefetchValidityMs)
FlakeIdGeneratorConfig
The IDs contain timestamp component, which ensures rough global ordering of IDs. If an ID is assigned to an object that was created much later, it will be much out of order. If you don't care about ordering, set this value to 0.
This setting pertains only to newId
calls made on the member
that configured it.
setPrefetchValidityMillis
in class FlakeIdGeneratorConfig
prefetchValidityMs
- the desired ID validity or unlimited, if <=0public FlakeIdGeneratorConfig setIdOffset(long idOffset)

IdGenerator
, default value works for all green-field projects.
For example: Largest ID returned from IdGenerator
is 150. FlakeIdGenerator
now
returns 100. If you configure idOffset
of 50 and stop using the IdGenerator
, the next
ID from FlakeIdGenerator
will be 151 or larger and no duplicate IDs will be generated.
In real-life, the IDs are much larger. You also need to add a reserve to the offset because the IDs from
FlakeIdGenerator
are only roughly ordered. Recommended reserve is 1<<38
,
that is 274877906944.
Negative values are allowed to increase the lifespan of the generator, however keep in mind that the generated IDs might also be negative.
