Abstract
A method and system for synchronization and distribution of configuration cross cluster without blocking are provided herein. The method includes: responsive to detecting a node in the group of nodes of a distributed system becoming inactive, recording current operations database version as a node version of the inactive node; initiating a removal of the inactive node from the group of nodes; maintaining the version of the operations database unchanged until the inactive node is removed; enabling a change of the database version once the removal of the inactive node is completed; sending a join request once the inactive node wishes to rejoin; obtaining a list of operation objects for synchronization of the rejoining node; and accepting the rejoining node to the group, only whenever the joining node is at a same state as the nodes group, otherwise, repeating the sending of the join request until the synchronization is completed.
