Oracle sharding architecture horizontally partitions data across discrete Oracle Databases (shards) that also collectively form a single logical database. In this session we will discuss our experience of using Oracle sharding for the business including: what type of application best fit to Oracle sharding, configuring sharded database with HA replication for massive scalability and complete fault isolation and some lessons learned. We will also discuss some new sharding features in Oracle 21c such as sharding with database in Persistent memory. Furthermore we will discuss our experience with Oracle sharding in Oracle Cloud Infrastructure including docker base deployment of Oracle Shard database and Oracle sharding database on Kubernetes. The audiences will not only learn our experience of using Oracle sharding to achieve massive scalability and complete fault isolation. They will also learn Oracle sharding in Oracle Cloud Infrastructure such as Oracle sharding in docker and Kubernetes platform
