Abstract
Embodiments relate to generating database sequences in a replicated database environment. An aspect includes providing a group of nodes each hosting an instance of a replicated database, with one node in the group elected as a master node responsible for generating and distributing values for auto-generated values in a column or row of the replicated database. Another aspect includes dividing, by the master node, a sequence space of possible auto-generated values for the column or row into sub-ranges and assigning a sub-range to a particular node in the group of nodes. Another aspect includes distributing, by the master node, values of the assigned sub-range to a particular node of the group of nodes.
