About Release 7.9.0
This site contains documentation for HPE Ezmeral Data Fabric release 7.9.0, including installation, configuration, administration, and reference content, as well as content for the associated ecosystem components and drivers.
7.9.0 Installation
This section contains information about installing and upgrading HPE Ezmeral Data Fabric software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a HPE Ezmeral Data Fabric cluster.
7.9.0 Data Fabric
HPE Ezmeral Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
- HPE Ezmeral Data Fabric File Store
  HPE Ezmeral Data Fabric File Store is a distributed file system for data storage, data management, and data protection. File Store supports mounting and cluster access via NFS and FUSE-based POSIX clients (basic, platinum, or PACC) and also supports access and management via HDFS APIs.
- HPE Ezmeral Data Fabric Object Store
  The HPE Ezmeral Data Fabric Object Store is a native object storage solution that efficiently stores objects and metadata for optimized access.
- HPE Ezmeral Data Fabric Database
  HPE Ezmeral Data Fabric Database is an enterprise-grade, high-performance, NoSQL database management system that you can use for real-time, operational analytics.
  - Architecture
    HPE Ezmeral Data Fabric Database is an enterprise-grade, high performance, NoSQL (“Not Only SQL”) database management system. You can use it to add realtime, operational analytics capabilities to big data applications. As a multi-model NoSQL database, it supports both JSON document models and key-value data models.
  - Data Models
    HPE Ezmeral Data Fabric Database can be used as both a document database and a column-oriented database. As a document database, JSON documents are stored in HPE Ezmeral Data Fabric Database JSON table. As a column-oriented database, binary files are in stored HPE Ezmeral Data Fabric Database binary tables.
  - Secondary Indexes
    Beginning with data-fabric 6.0, HPE Ezmeral Data Fabric Database JSON natively supports secondary indexes on fields in JSON tables. Indexes provide you with flexible, high performance access to data stored in HPE Ezmeral Data Fabric Database.
  - Change Data Capture
    The Change Data Capture (CDC) system allows you to capture changes made to data records in HPE Ezmeral Data Fabric Database tables (JSON or binary) and propagate them to a HPE Ezmeral Data Fabric Streams topic.
  - Table Replication
    You can replicate data in one table to another table that is in the same cluster or in a separate cluster. This type of replication is in addition to the automatic replication that occurs with table regions within a volume.
  - Gateways for Indexing HPE Ezmeral Data Fabric Database Data in Elasticsearch
    As of data-fabric 6.0, HPE Ezmeral Data Fabric Database Elastic Search integration capability is deprecated and no longer available in the HPE Ezmeral Data Fabric Database product.
- HPE Ezmeral Data Fabric Streams
  HPE Ezmeral Data Fabric Streams brings integrated publish and subscribe messaging to the HPE Ezmeral Data Fabric.
- HPE Ezmeral Unified Analytics
  Describes the HPE Ezmeral Unified Analytics Software and provides a link to more information.
- Kubernetes Interfaces for Data Fabric
  This section describes the Kubernetes Interfaces for Data Fabric, which include the Container Storage Interface (CSI) driver for multiple container-orchestration systems, and the FlexVolume driver for Kubernetes.
- Cluster Management
  Provides a synopsis of the various cluster components and their management.
- Performance
  Describes how to tune system performance, manage RDMA, and optimize CLDB tables.
- Security
  Provides an overview of the Data Fabric security features.
- YARN
- Client Connections
  The following sections describe how a client connects to local and remote data-fabric clusters.
7.9.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
7.9.0 Development
This section contains information related to application development for Ezmeral ecosystem components and HPE Ezmeral Data Fabric products, including the file system, Database (Key-Value and JSON), and Event Streams.
Other Docs

HPE Ezmeral Data Fabric Database

HPE Ezmeral Data Fabric Database is an enterprise-grade, high-performance, NoSQL database management system that you can use for real-time, operational analytics.

Why HPE Ezmeral Data Fabric Database?

HPE Ezmeral Data Fabric Database is built into the HPE Ezmeral Data Fabric platform. It requires no additional process to manage, leverages the same architecture as the rest of the platform, and requires minimal additional management.

What databases does the HPE Ezmeral Data Fabric Database include?

The HPE Ezmeral Data Fabric Database includes two NoSQL databases:

Key-value and columnar database with HBase API
- Supports Apache HBase tables and databases.
- Provides a native implementation of the HBase API for optimized performance on the Data Fabric platform.
JSON document database based on the OJAI API
- Supports JSON documents as a native data store.
- Stores JSON documents in HPE Ezmeral Data Fabric Database JSON tables.
- Starting in HPE Ezmeral Data Fabric 7.0.0, all fields of JSON tables support DDM (dynamic data masking). The JSON database supports eight predefined dynamic data masks.
