In this post, we will take a look at the advantages of Oracle Sharding.

  • Linear scalability with complete fault isolation. OLTP applications designed for Oracle sharding can elastically scale (data, transactions and users) to any level, on any platform, simply by deploying new shards on additional stand-alone servers.

Upon the unavailability of a shard, failover is initiated automatically to another copy of the data. Each shard may run a different release of the Oracle Database as long as the application is backward compatible with the oldest running version – making it simple to maintain availability of an application while performing database maintenance.
