The contents of a Hadoop data lake need not be immediately incorporated into a formal database schema or consistent data structure, which allows users to store raw data as is; information can then either be analyzed in its raw form or prepared for specific analytics uses as needed. New embedded analytics capabilities highlight the latest additions to the QuickSight platform, but despite improving capabilities... Data streaming processes are becoming more popular across businesses and industries. genomic and clinical analytics). As big data applications become more prevalent in companies, the data lake often is organized to support a variety of applications. Information is power, and a data lake puts enterprise-wide information into the hands of many more employees to make the organization as a whole smarter, more agile, and more innovative. Hadoop architecture is an open-source framework that is used to process large data easily by making use of the distributed computing concepts where the data is spread across different nodes of the clusters. The. The main components of Azure Data Lake are Azure Data Lake Analytics, which is built on Apache YARN, Azure Data Lake Store and U-SQL. At this point, the enterprise data lake is a relatively immature collection of technologies, frameworks, and aspirational goals. Data Lake Architecture. After all, “information is power” and corporations are just now looking seriously at using data lakes to combine and leverage all of their information sources to optimize their business operations and aggressively go after markets. Once gathered together (from their “information silos”), these sources can be combined and processed using big data, search and analytics techniques which would have otherwise been impossible. - It is expected that these insights and actions will be written up and communicated through reports. Meanwhile, data warehouse advocates contend that similar architectures -- for example, the data mart -- have a long lineage and that Hadoop and related open source technologies still need to mature significantly in order to match the functionality and reliability of data warehousing environments. - We anticipate that common text mining technologies will become available to enrich and normalize these elements. we will discuss the sources for Data lake perspective.
