This section provides support for accessing the key/value store functionality on HPCC Systems clusters. The Store module allows you to create stores, manage namespaces, and perform key/value operations for persisting data across workunit executions.
The Store module provides a persistent key/value storage mechanism that allows data to be stored and retrieved across multiple workunit executions. The key/value store is organized hierarchically:
Stores: Top-level containers that hold namespaces. Stores can be global (accessible to all users) or user-specific (private to an individual user).
Namespaces: Logical partitions within stores that group related keys together.
Keys: Named identifiers that map to stored values. Keys can be global or user-specific.
Values: String data associated with keys.
The Store module requires authentication credentials and can operate against a specific ESP URL or use the default ESP process on the cluster.
