Definitely, YugabyteDB falls into the second category. Tables are split into so called tablets. This splitting can be controlled by choosing the hashing algorithm for the primary key (or transparent row key hash, if no primary key for a table exists). Each tablet is replicated and has its own raft group. Different tables can have different replication factors, the number of tablets to split the table into can be selected and modified. YugabyteDB recently added support for table spaces on steroids where table spaces are allocated to physical nodes in the cluster. This enables geo-replication features where tables or rows can be placed within selected geo locations. All the data shifting is done transparently by the database. |
