Subject Re: SYSTEM.SEQUENCE is created with 256 regions by default now?
Date Wed, 01 Jul 2015 22:39:27 GMT
Yes, since 4.2.2. The number of regions is controlled by
the phoenix.sequence.saltBuckets property (only the first time
SYSTEM.SEQUENCE is created):

Here are a couple of mailing list threads where this was discussed before
(there are quite a few others too):
