Description

Feature that allows users to choose between HA and SC modes for partitions. The SC mode corresponds to the current behavior in Ignite 3, where strong data consistency is maintained, and any loss of majority leads to unavailability. In the HA mode, users will be able to read and write data from the surviving nodes even when the majority is lost, accepting the potential trade-off of possible data loss
