6.0 Development
This section contains information related to application development for ecosystem components and MapR products including MapR-DB (binary and JSON), MapR-FS, and MapR Streams.
- Application Development Process
  Before you start developing applications on MapR’s Converged Data Platform, consider how you will get the data onto the platform, the format it will be stored in, the type of processing or modeling that is required, and how the data will be accessed.
- MapR-FS and Apps
  The following sections provide information about accessing MapR-FS with C and Java applications.
- MapR-DB and Apps
  This section contains information about developing client applications for JSON and binary tables.
- MapR-ES and Apps
  MapR-ES brings integrated publish and subscribe messaging to the MapR Converged Data Platform.
  - Getting Started with MapR-ES
    If you have a basic understanding of MapR-ES's components and the typical flow of messages from producers to consumers, you can give MapR-ES a try.
  - Consuming CDC Records
    The OJAI changelog interfaces are used to consume changed data records (propagated by the Change Data Capture feature).
  - Consuming Audit Logs
    Audit Streaming (available from v6.0.1) provides a way to process the audit data in real-time.
  - MapR-ES Java Applications
    This section contains information on developing client applications with Java including information about the MapR-ES and Apache Kafka Java APIs, configuration parameters, and compiling and running producers and consumers.
  - MapR-ES C Applications
    C applications can be developed for MapR-ES (as of MapR 5.2.1). The MapR-ES C Client is a distribution of librdkafka that works with MapR-ES. The MapR-ES C Client is available in MapR Ecosystem Pack (MEP) 3.0 or higher.
  - MapR-ES Python Applications
    As of MapR 5.2.1, you can create python applications for MapR-ES using the MapR-ES Python client. The MapR-ES Python client is a binding for librdkafka and the MapR-ES C Client is a distribution of librdkafka that works with MapR-ES.
  - MapR-ES C#/.NET Applications
    As of MapR 6.0.1/MEP5.0, you can create C#/.NET applications for MapR-ES using the MapR-ES C#/.NET client. The MapR-ES C#/.NET client is a binding for librdkafka and the MapR-ES C Client is a distribution of librdkafka that works with MapR-ES.
  - Utilities for MapR-ES
    MapR-ES provides the utilities for operating on streams and topics.
  - Configuring Properties for Message Size
    Describes the message.max.bytes and receive.message.max.bytes properties for configuring message size.
- MapReduce and Apps
  This section contains information associated with developing YARN applications.
- MapR Data Science Refinery
  The MapR Data Science Refinery is an easy-to-deploy and scalable data science toolkit with native access to all platform assets and superior out-of-the-box security.
- MapR Data Fabric for Kubernetes FlexVolume Driver

  This section discusses topics associated with Maven and MapR.
- Developer's Reference
  This section contains in-depth information for the developer.
- API Documentation
  MapR supports public APIs for MapR-FS, MapR-DB, and MapR-ES. These APIs are available for application development purposes.

MapR-ES and Apps

MapR-ES brings integrated publish and subscribe messaging to the MapR Converged Data Platform.

MapR-ES is built into the MapR platform. It requires no additional process to manage, leverages the same architecture as the rest of the platform, and requires minimal additional management.
