8.0.0 Development
This section contains information related to application development for Ezmeral ecosystem components and HPE Data Fabric products, including the file system, Database (Key-Value and JSON), and Event Streams.
- Application Development Process
  Before you start developing applications on the HPE Data Fabric platform, consider how you will get the data into the platform, the storage format of the data, the type of processing or modeling that is required, and how the data will be accessed.
- File Store and Apps
  The following sections provide information about accessing the File Store with C and Java applications.
- HPE Data Fabric Database and Apps
  This section contains information about developing client applications for JSON and key-value tables.
  - Installing the mapr-client Package
    The mapr-client package must be installed on each node where you will be building and running your applications. This package installs all of the MapR Libraries needed for application development regardless of programming language or type of HPE Data Fabric Database table (binary or JSON).
  - Passing the HPE Data Fabric Database Table Path
    This topic describes the methods for passing a HPE Data Fabric Database table name. Binary table names can be passed by either specifying the table path in the API or by setting the table path in the core-site.xml file. JSON table names are passed by specifying the table path in the API.
  - Tuning Parameters for Client Apps
    Though tuning client applications is generally not necessary, Data Fabric does offer tuning parameters to change the behavior of client-side caching.
  - Developing Applications for Binary Tables
    HPE Data Fabric Database provides a C API, libMapRClient and partially supports the Apache HBase 1.1 Java APIs for performing operation on HPE Data Fabric Database binary tables.
  - Setting for OJAI Applications to Use Data Fabric Client Features
    Describes how to set the classpath for OJAI applications to use Data Fabric client features.
  - Developing Applications for JSON Tables
    As part of its support for JSON tables, HPE Data Fabric Database implements the OJAI API. The OJAI API provides methods for creating, reading, updating, and deleting JSON documents in HPE Data Fabric Database JSON tables. It is available in Java, and starting in EEP 6.0, also available in Node.js, Python, C#, and Go. HPE Data Fabric Database also provides a HPE Data Fabric Database JSON Client API for managing JSON tables and a HPE Data Fabric Database JSON REST API for performing basic operations using HTTP calls.
    - Managing JSON Tables
      This section describes how to create, list, and delete JSON tables, alter JSON table attributes, set permissions, and manage column families. You can perform these operations using either the HPE Data Fabric Database JSON Client API library or HPE Data Fabric Database Shell commands.
    - Managing JSON Documents
      To perform CRUD operations (create, read, update, and delete) on JSON documents in HPE Data Fabric Database JSON tables using the OJAI API, you use Document, DocumentStore, and DocumentMutation objects.
    - Querying JSON Documents
      This section describes how to query JSON documents in HPE Data Fabric Database JSON tables using the OJAI API library and HPE Data Fabric Database Shell. It includes sample programs using the OJAI API library and shows how to run the same queries in HPE Data Fabric Database Shell.
    - Querying with HPE Data Fabric Database Shell
      This section describes how to query JSON documents using either the find or findbyid command in HPE Data Fabric Database Shell (dbshell). It introduces the functionality the find command supports and describes the two ways to specify your queries. It also provides links to reference pages and examples.
    - Examples: Querying JSON Documents
      This section provides query examples using the OJAI API. The examples include querying by document ID, retrieving all documents in a store, selecting individual fields, specifying query conditions, and ordering your query result. For reference, the examples also include the equivalent HPE Data Fabric Database Shell (dbshell) commands.
    - Using the Java OJAI Client
      This topic describes HPE Data Fabric Database functionality that is applicable to only the Java OJAI client. This includes instructions on how to compile your Java OJAI application, enable buffered writes, use the read your own writes feature, and enable available query options.
    - Using the Java OJAI Thin Client
      Starting with EEP 6.3.0, you can use the Java OJAI Thin Client to write HPE Data Fabric Database JSON applications. The Java OJAI Thin Client provides a lightweight library that supports the OJAI API. You can connect to HPE Data Fabric Database JSON, and add, update, and query documents in a HPE Data Fabric Database JSON table.
    - Using the Node.js OJAI Client
      Starting with EEP 6.0, you can use the Node.js OJAI client to write HPE Data Fabric Database JSON applications. The client provides you with a lightweight library that supports the OJAI API. You can connect to HPE Data Fabric Database JSON from middleware components, and add, update, and query documents in a HPE Data Fabric Database JSON table.
    - Using the Python OJAI Client
      Starting with EEP 6.0, you can use the Python OJAI client to write HPE Data Fabric Database JSON applications. The client provides you with a lightweight library that supports the OJAI API. You can connect to HPE Data Fabric Database JSON, and add, update, and query documents in a HPE Data Fabric Database JSON table.
    - Using the C# OJAI Client
      Starting with EEP 6.1.0, you can use the C# OJAI client to write HPE Data Fabric Database JSON applications. The client provides you with a lightweight library that supports the OJAI API. You can connect to HPE Data Fabric Database JSON, and add, update, and query documents in a HPE Data Fabric Database JSON table.
    - Using the Go OJAI Client
      Starting with EEP 6.0.0, you can use the Go OJAI client to write HPE Data Fabric Database JSON applications. The client provides you with a lightweight library that supports the OJAI API. You can connect to HPE Data Fabric Database JSON, and add, update, and query documents in a HPE Data Fabric Database JSON table.
    - Configuring SSL for OJAI Clients
      Describes certificates and how to configure SSL for OJAI clients, including which PEM file to point to and how to determine which DAG host name to use.
    - Using the HPE Data Fabric Database JSON REST API
      Starting in the EEP 5.0 release, you can use a REST API to access HPE Data Fabric Database JSON tables. The REST API allows you to use HTTP calls to perform basic operations on HPE Data Fabric Database JSON tables.
      - Getting Started with the HPE Data Fabric Database JSON REST API
        A simple way to invoke the HPE Data Fabric Database JSON REST API is to use cURL commands. This section contains a sequence cURL commands that demonstrate the basic functionality of the API.
      - Understanding the HPE Data Fabric Database JSON REST API
        The section describes the details of the HPE Data Fabric Database JSON REST API.
        POST /auth/v2/token
        Authenticates a user. If successful, creates an authentication token that you use in subsequent API requests. By default, the token expires in 30 minutes. After a token expires, you must rerun this command to generate a new token.
        PUT /api/v2/table/{path}
        Creates a HPE Data Fabric Database JSON table
        DELETE /api/v2/table/{path}
