Leveraging Hadoop with in-memory computing

Continuing with the report on In-memory computing solutions, this post looks at 15 more companies which are leveraging Hadoop. A few notes on the methodology used:

The companies listed below have been independently validated to be using 'In-memory computing' in their solutions.
Hadoop usage may not come off as a direct use case in some of these solutions. Our focus is to investigate how Hadoop is complementing In-memory computing rather than being bete-noir of each other.
Open source solution name Apache Gora is not listed here. To read more extensively on it, click here.

Listed below are 15 more IMC companies and their Hadoop connection tactics.

	Company	Product	Hadoop integration tactic
16.	PrismTech	OpenSlice	PrismTech’s OpenSplice DDS enables seamless, timely, scalable and dependable distributed data sharing from embedded and mobile Devices to the enterprise and the cloud. OpenSlice Gateway supports Apache Camel Connectors for Big Data Stores which aids in streaming data to/from Hbase.
17.	QlikTech	Qlikview	The ODBC Connector for Qlikview enables enterprise users to access Hadoop data through the Business Intelligence Application Qlikview. The driver achieves this by translating Open Database Connectivity (ODBC) calls from Qlikview into SQL and passing the SQL queries to the underlying Impala or Hive engines.
18.	Red Hat	Red Hat Enterprise MRG Grid & JBoss Grid	Red Hat Enterprise MRG Grid aims to provide job and resource scalability and job throughput and performance in heterogeneous environments. It provides a common interface for submission, monitoring and reporting of Hadoop MapReduce jobs. Further it aims to provide intelligence to match jobs with resources. It helps to dispatch jobs and data to resources while managing multiple users, groups and resources.
19.	SAP	SAP Real Time Data Platform	SAP Real-Time Data Platform now combines Hadoop with following SAP technologies like: - SAP HANA – in memory DB for faster access; - SAP Sybase IQ- for ‘federated’ queries by considering HDFS/Hive as external DB and joining results in Sybase; - SAP Data Services – for data interactions using HiveQL or Pig; - SAP Information Steward – for improving data quality; - SAP Sybase Event Stream Processor – real time analysis of events & data and pushing required data to HDFS; - SAP BusinessObjects, SAP BusinessObjects Explorer and SAP Crystal Reports – for reporting, visualization and building data models.
20.	SAS Institute	SAS/ACCESS Interface to Hadoop	SAS In-Memory Analytics is used by multiple solutions and capabilities from SAS product family (for instance, SAS Visual Analytics). For Hadoop integration, SAS/ACCESS retrieves big data stored in HDFS and allows using other capabilities, such as the Pig and Hive languages and the MapReduce framework. SAS programmers can submit MapReduce, scripting and HDFS commands from within Base SAS. SAS also supports external file references, allowing you to conveniently find and use Hadoop files from any SAS product.
21.	ScaleOut Software	ScaleOut hServer	ScaleOut hServer provides an integrated in-memory data grid and computation engine that executes standard Hadoop MapReduce code in-parallel, in-memory through its own Hadoop MapReduce execution engine. Like Hadoop, ScaleOut hServer performs data-parallel computation in which application code is sent to every node in the grid. However, unlike standard Hadoop, which stores data on disk and moves it multiple times during processing, ScaleOut hServer's integrated in-memory data grid minimizes data motion by enabling input and output data sets, as well as intermediate data, to be stored in the IMDG. Customized, grid record readers and writers for IMDG data efficiently pipeline key/value pairs to the mappers and from the reducers.
22.	Software AG	Terracotta BigMemory-Hadoop Connector	Terracotta's BigMemory-Hadoop Connector lets Hadoop jobs write data directly into BigMemory, Terracotta’s in-memory data management platform. This enables downstream applications to get instant access to Hadoop results by reading from BigMemory. Hadoop jobs also execute faster, as they can now write to memory instead of disk (HDFS).
23.	SQLstream	SQLstream Connector for Hadoop	SQLstream is a 'NoDatabase' technology, no data are stored, instead data arrives as real-time streams and processed in-memory. The SQLstream Connector for Hadoop provides continuous integration with Hadoop HBase, enabling organizations to exploit the value of both real-time analytics over the arriving data, and to persist machine data and streaming intelligence in Hadoop HBase for further analysis.
24.	Teradata	Teradata Intelligent Memory	Teradata Intelligent Memory is another best-of-breed solution that fits into the overall Unified Data Architecture strategy, which leverages Teradata, Teradata Aster, and open source Apache™ Hadoop. Data in Apache Hadoop that is frequently used can be accessed through Teradata SQL-H, and based on temperature of the data, moved to Intelligent Memory to take advantage of its high performance computing capability.
25.	Tervela	Tervela Turbo	Tervela Turbo, a high-performance data movement engine, helps to implement mission-critical Hadoop systems with reliable data capture, high-speed data loading into HDFS, disaster recovery for Hadoop, and ETLT data warehousing. Tervela Turbo's no-loss data fabric technology captures data from virtually any source system and transports it to HDFS for loading, eliminating failures that stem from common file transfer and network errors.
26.	Tibco Software	TIBCO ActiveSpaces	TIBCO ActiveSpaces uses a connector approach to integrate Hadoop MapReduce, Pig and Hive. The first part integrates ActiveSpaces into the core MapReduce functionality, and provides an InputFormat and an OutputFormat for ActiveSpaces. For data flows in Pig, the connector supplies a LoadFunc and a StoreFunc that allow full interoperability between Pig and ActiveSpaces. The connector supplies a Hive StorageHandler to write HiveQL.
27.	Vitria	Vitria Operational Intelligence (OI)	Vitria OI's Hadoop connector allows the solution to work synergistically alongside Hadoop. While Hadoop delivers deep insights into massive volumes of stored data, Vitria OI complements it by providing continuous, real-time insights into streaming data together with the ability to take proactive, automated action. The Hadoop connector allows data streaming into Vitria OI to be persisted in Hadoop, and queried to provide historical and baseline analysis. Data captured by Hadoop can be streamed into Vitria OI, which provides instant analysis and timely detection of opportunities and threats. Data streamed from Hadoop can also be used within the Vitria OI Apps, which empower business users to directly create value from Hadoop data.
28.	VoltDB	VoltDB Enterprise Edition	VoltDB Enterprise Edition V1.3.3 contains a new export client that exports data from VoltDB into a Hadoop distributed filed system (hdfs) using the Apache Sqoop. The Export-to-Hadoop client operates in much the same way as the existing export-to-file client, but gives Export data access to the format flexibility that Sqoop offers. The VoltDB export client automatically manages periodic Sqoop jobs based on your configuration.
29.	Workday	Workday Big Data Analytics	Workday Big Data Analytics incorporates Datameer’s Hadoop-driven analytics platform, which enables users to integrate, analyze, and visualize data of any type, size, or source. On the backend, the setup will initially be based on Amazon Web services, including S3, EC2, and the Elastic MapReduce. In the future the setup will be run on Cloudera's Hadoop distribution hosted in Workday's data center.
30.	WSO2	WSO2 Complex Event Processor	WSO2 CEP tightly Integrates with WSO2 Business Activity Monitor which supports recording and post processing of events with Map-Reduce via Apache Hadoop. Business Activity Monitor provides SQL-like flexibility for writing analysis algorithms via Apache Hive and extensibility via analysis algorithms implemented in Java. Results from analysis can be stored flexibly, including in Apache Cassandra, a relational database or a file system.

Data deduplication tactics with HDFS and MapReduce

As the amount of data continues to grow exponentially, there has been increased focus on stored data reduction methods. Data compression, single instance store and data deduplication are among the common techniques employed for stored data reduction.
Deduplication often refers to elimination of redundant subfiles (also known as chunks, blocks, or extents). Unlike compression, data is not changed and eliminates storage capacity for identical data. Data deduplication offers significant advantage in terms of reduction in storage, network bandwidth and promises increased scalability.
From a simplistic use case perspective, we can see application in removing duplicates in Call Detail Record (CDR) for a Telecom carrier. Similarly, we may apply the technique to optimize on network traffic carrying the same data packets.
Some of the common methods for data deduplication in storage architecture include hashing, binary comparison and delta differencing. In this post, we focus on how MapReduce and…
