Websphere ECKeyManager getNextKey randomness

Question

Say that I have a table and I run the following:

Long key = ECKeyManager.singleton().getNextKey("my_table");

Where

LOWERBOUND=100,
UPPERBOUND=999

My question is: If I run this two times in sequence, will the returned 'keys' be sequential or 'random' withing the bounds?

Answer 1

It depends on the prefetchsize and counter values configured for the table in keys table. The prefetchsize would be the starting value that is retrieved and the next value would be the "prefetchsize+counter" value
