Hot Rod C++ Client Guide

Red Hat Data Grid 8.1

Configure and use Hot Rod C++ clients

Red Hat Customer Content Services

Abstract

Hot Rod C++ clients allow C++ runtime applications to connect and interact with remote Data Grid clusters.

Red Hat Data Grid
링크 복사

Data Grid is a high-performance, distributed in-memory data store.

Schemaless data structure
Flexibility to store different objects as key-value pairs.
Grid-based data storage
Designed to distribute and replicate data across clusters.
Elastic scaling
Dynamically adjust the number of nodes to meet demand without service disruption.
Data interoperability
Store, retrieve, and query data in the grid from different endpoints.

Data Grid documentation

Note

You must have a Red Hat account to access and download Data Grid software.

Making open source more inclusive
링크 복사

Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.

Chapter 1. Installing the Hot Rod C++ client
링크 복사

Install the Hot Rod C++ client on your host system as a dynamic library.

1.1. C++ compiler requirements
링크 복사

Expand
Operating systemRequired compiler

Red Hat Enterprise Linux (RHEL) 8

C++ 11 compiler (GCC 8.5.0)

RHEL 9

C++ 11 compiler (GCC 11.3.1)

Microsoft Windows 7 x64

C++ 11 compiler (Visual Studio 14 2015 Win64, Microsoft Visual C++ 2013 Redistributable Package for the x64 platform)

1.2. Installing Hot Rod C++ clients on Red Hat Enterprise Linux (RHEL)
링크 복사

Data Grid provides an RPM distribution of the Hot Rod C++ client for RHEL.

Procedure

  1. Enable the repository for the Hot Rod C++ client on RHEL.

    Expand
    RHEL versionRepository

    RHEL 8

    jb-datagrid-8.4-for-rhel-8-x86_64-rpms

    RHEL 9

    jb-datagrid-8.4-for-rhel-9-x86_64-rpms

  2. Install the Hot Rod C++ client. 

    # yum install jdg-cpp-client

1.3. Installing Hot Rod C++ clients on Microsoft Windows
링크 복사

Data Grid provides an archived version of the Hot Rod C++ client for installation on Windows.

Procedure

  1. Download the ZIP archive for the Hot Rod C++ client from the Data Grid Software Downloads.
  2. Extract the ZIP archive to your file system.

Chapter 2. Compiling Protobuf Schema
링크 복사

Data Grid uses the ProtoStream API to store data as Protobuf-encoded entries.

Protobuf is a language-neutral format that allows clients to create and retrieve entries in remote caches using both Hot Rod and REST endpoints.

2.1. Compiling Protobuf schema on Red Hat Enterprise Linux (RHEL)
링크 복사

Compile Protobuf schema, .proto files, into C++ header and source files to describe your data to Data Grid.

Prerequisites

  • Install the Protobuf library and protobuf-devel package. 

    # yum install protobuf
# yum install protobuf-devel
    Copy to Clipboard Toggle word wrap

Procedure

  1. Set the LD_LIBRARY_PATH environment variable, if it is not already set. 

    # export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/lib64
    Copy to Clipboard Toggle word wrap

  2. Compile Protobuf schema for the Hot Rod C++ client as required. 

    # /bin/protoc --cpp_out dllexport_decl=HR_PROTO_EXPORT:/path/to/output/ $FILE
    Copy to Clipboard Toggle word wrap

    HR_PROTO_EXPORT is a macro that the Hot Rod C++ client expands when it compiles the Protobuf schema.

  3. Register your Protobuf schema with Data Grid if you plan to use queries.

2.2. Compiling Protobuf schema on Microsoft Windows
링크 복사

Compile Protobuf schema, .proto files, into C++ header and source files to describe your data to Data Grid.

Procedure

  1. Open a command prompt to the installation directory for the Hot Rod C++ client.

  2. Compile Protobuf schema for the Hot Rod C++ client as required. 

    bin\protoc --cpp_out dllexport_decl=HR_PROTO_EXPORT:path\to\output\ $FILE
    Copy to Clipboard Toggle word wrap

    HR_PROTO_EXPORT is a macro that the Hot Rod C++ client expands when it compiles the Protobuf schema.

  3. Register your Protobuf schema with Data Grid if you plan to use queries.

Chapter 3. Configuring the Hot Rod C++ client
링크 복사

Hot Rod C++ clients interact with remote Data Grid clusters via the RemoteCache API.

3.1. Configuration and Remote Cache Manager APIs
링크 복사

Use the ConfigurationBuilder API to configure Hot Rod C++ client connections and the RemoteCacheManager API to obtain and configure remote caches.

Configuration builder

#include "infinispan/hotrod/ConfigurationBuilder.h"
#include "infinispan/hotrod/RemoteCacheManager.h"
#include <infinispan/hotrod/RemoteCache.h>
#include <iostream>
int main () {
  ConfigurationBuilder builder;
    // Configure a cache manager to connect with Hot Rod version 2.8
    builder.protocolVersion(Configuration::PROTOCOL_VERSION_28);
    // Connect to a server at localhost with the default port.
    builder.addServer().host("127.0.0.1").port(11222);
    // Create and start a RemoteCacheManager to interact with caches.
    RemoteCacheManager cacheManager(builder.build(), false);
    cacheManager.start();
    ...
}

Cross-site replication

ConfigurationBuilder builder;
  builder.addServer().host("127.0.0.1").port(11222);
  // Configure a remote cluster and node when using cross-site replication.
  builder.addCluster("NYC").addClusterNode("192.0.2.0", 11322);

Near caching

ConfigurationBuilder builder;
  builder.addServer().host("127.0.0.1").port(11222);
  // Enable near-caching for the client.
  builder.nearCache().mode(NearCacheMode::INVALIDATED).maxEntries(4);
