Administering Tables
Administration of the HPE Ezmeral Data Fabric Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the HPE Ezmeral Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Ezmeral Data Fabric Database administration is associated with tables, columns and column families, and table regions.
Why use HPE Ezmeral Data Fabric Database?
From an administrator's point-of-view, HPE Ezmeral Data Fabric Database provides the
following capabilities:
- Minimal administration: Single namespace for files, tables and streams, flexible schema that allows built-in data management and protection, automatic splits and merges as data grows and shrinks, and easy bulk data loading.
- Self-healing from HW and SW failures: Replicated state and data for instant recovery and automated re-replication of data.
- Global low-latency replication: Multi-master (that is, active to active) replication which is important for disaster recovery. Includes reduced risk of data loss, application failover, and faster data access.
- High performance and low latency: Integrated system with fewer software layers, single hop to data, and no compactions with low I/O amplification.
- Fine-grained security: Access permissions can be granted to tables (as well as files and streams) at a granular level using Access Control Expressions (ACEs), which are designed for flexibility and ease-of-use.
