Introduction to sharding
Sharding separates large databases into smaller, more easily managed parts called database shards that can be spread across multiple database servers.
In IBM® Sterling Order Management System Software, a colony is a set of database shards and is determined by a configurable set of attributes.
Additional sharding considerations
Note the following sharding considerations:
- If two enterprises share customer master data or catalog master data, they must also share the same Master shard and hence, must belong to same colony.
- If a colony has existing Master and Transaction data combined together in one shard, the colony continues to have Master and Transaction data combined, even after upgrades.
- Resharding is not supported in Sterling Order Management System Software.
