    MEAP Edition Manning Early Access Program The Programmer’s Guide to Apache Thrift Version 5 Copyright 2013 Manning Publications For more information on this and other Manning titles go to www.manning.com ©Manning Publications Co. We welcome reader comments about anything in the manuscript - other than typos and other simple mistakes. These will be cleaned up during production of the book by copyeditors and proofreaders. http://www.manning-sandbox.com/forum.jspa?forumID=873 Licensed to Daniel Gavrila <[email protected]> Welcome Hello and welcome to the third MEAP update for The Programmer’s Guide to Apache Thrift. This update adds Chapter 7, Designing and Serializing User Defined Types. This latest chapter is the first of the application layer chapters in Part 2. Chapters 3, 4 and 5 cover transports, error handling and protocols respectively. These chapters describe the foundational elements of Apache Thrift. Chapter 6 describes Apache Thrift IDL in depth, introducing the tools which enable us to describe data types and services in IDL. Chapters 7 through 9 bring these concepts into action, covering the three key applications areas of Apache Thrift in turn: User Defined Types (UDTs), Services and Servers. Chapter 7 introduces Apache Thrift IDL UDTs and provides insight into the critical role played by interface evolution in quality type design. Using IDL to effectively describe cross language types greatly simplifies the transmission of common data structures over messaging systems and other generic communications interfaces. Chapter 7 demonstrates the process of serializing types for use with external interfaces, disk I/O and in combination with Apache Thrift transport layer compression.

  • Getting Started with Apache Avro
    Getting Started with Apache Avro By Reeshu Patel Getting Started with Apache Avro 1 Introduction Apache Avro Apache Avro is a remote procedure call and serialization framework developed with Apache's Hadoop project. This is uses JSON for defining data types and protocols, and tend to serializes data in a compact binary format. In other words, Apache Avro is a data serialization system. Its frist native use is in Apache Hadoop, where it's provide both a serialization format for persistent data, and a correct format for communication between Hadoop nodes, and from client programs to the apache Hadoop services. Avro is a data serialization system.It'sprovides: Rich data structures. A compact, fast, binary data format. A container file, to store persistent data. Remote procedure call . It's easily integration with dynamic languages. Code generation is not mendetory to read or write data files nor to use or implement Remote procedure call protocols. Code generation is as an optional optimization, only worth implementing for statically typewritten languages. Schemas of Apache Avro When Apache avro data is read, the schema use when writing it's always present. This permits every datum to be written in no per-value overheads, creating serialization both fast and small. It also facilitates used dynamic, scripting languages, and data, together with it's schema, is fully itself-describing. 2 Getting Started with Apache Avro When Apache avro data is storein a file, it's schema is store with it, so that files may be processe later by any program. If the program is reading the data expects a different schema this can be simply resolved, since twice schemas are present.

  • Apache Flume™
    ™ Apache Flume™ Flume 1.7.0 User Guide Introduction Overview Apache Flume is a distributed, reliable, and available system for efficiently collecting, aggregating and moving large amounts of log data from many different sources to a centralized data store. The use of Apache Flume is not only restricted to log data aggregation. Since data sources are customizable, Flume can be used to transport massive quantities of event data including but not limited to network traffic data, social-media-generated data, email messages and pretty much any data source possible. Apache Flume is a top level project at the Apache Software Foundation. There are currently two release code lines available, versions 0.9.x and 1.x. Documentation for the 0.9.x track is available at the Flume 0.9.x User Guide. This documentation applies to the 1.4.x track. New and existing users are encouraged to use the 1.x releases so as to leverage the performance improvements and configuration flexibilities available in the latest architecture. System Requirements 1. Java Runtime Environment - Java 1.7 or later 2. Memory - Sufficient memory for configurations used by sources, channels or sinks 3. Disk Space - Sufficient disk space for configurations used by channels or sinks 4. Directory Permissions - Read/Write permissions for directories used by agent Architecture Data flow model A Flume event is defined as a unit of data flow having a byte payload and an optional set of string attributes. A Flume agent is a (JVM) process that hosts the components through which events flow from an external source to the next destination (hop).
