security and managed LDAP integration, integration with Infosphere DataStage for extraction, transformation, loading (ETL), commonly used accelerators for use cases, such as log and machine data analysis, and application directories containing common directories and reusable work ; Eclipse plug-in; and Bigindex, which is actually a Lucene indexing tool built on Hadoop. You can also improve performance with adaptive MapReduce, compressed text files,

good idea), the database used Oracle.All the big banks come up with a summary of the data, these scripts, responsible for data processing filtering, reorganization, and finally get a table to meet customer needs. I heard that they can analyze the risk of the project from this table, in fact, I do not see. It seems that the good point is ETL, English extract-transform-load abbreviation. The project requirement is that a bank will add several overseas branches, so the job to summarize the data sh

directory structure from the main library.4. The architecture of the master-slave library hardware system must be the same. For example: The main library is running on a 64-bit sun SPARC system, which is not allowed if the Linux Intel system is 32-bit from the library. The configuration of the master-slave library hardware can be different, such as: Number of CPUs, memory size, storage configuration, etc.Reference Document: Http://blog.chinaunix.net/uid-14877370-id-2782040.html-----------------

corrected, it should be removed. Some data records are unstructured, and it is difficult to convert them into a new unified format. In addition, the entire file must be read from the extracted information, which is extremely inefficient, such as large-capacity binary data files, multimedia files and so on. If this type of data is difficult for enterprises to make decisions, they can be removed. Some software vendors have developed specialized ETL tools, including: Ardent

The system is not active recently and has not been upgraded. Therefore, you can optimize the entire ETL system on a stable basis. Top 10 cost time jobs are listed on a daily basis for analysis. The top1 costtime job uses the window functions first_value and last_value. The result SQL uses first_value, the window functions are sorted twice. Use the explain Section Code It can be found that the two sort consumption is about 1.7 times that of one sort, the second sort is improved to one, and the S

project ~ 80%. This is a general consensus obtained from many practices at home and abroad.ETL is a process of data extraction (Extract), Cleaning (Cleaning), transformation (Transform), and Load (Load. It is an important part of building a data warehouse. The user extracts the required data from the data source, cleans the data, and finally loads the data to the data warehouse according to the pre-defined data warehouse model.Therefore, how enterprises use various technical means and convert d

function: must be extracted to the data can be flexible calculation, merging, split and other conversion operations. At present, the typical representative of ETL tools are: Business software: Informatica, IBM Datastage, Oracle ODI, Microsoft SSIS ...

encyclopedia content, personal kettle used more, the other two used relatively little. In fact, whether it is open source or commercial ETL tools have their own job scheduling, but from the use of flexibility and simplicity, it is not as good as the third-party professional to do batch job scheduling tools. Since they are all tools to facilitate the use of people, why not use better tools to relieve our workload, so that we can devote more effort to the business itself. Here is to share a third

Four, ETL tools: In traditional industry data warehousing projects, most of the existing ETL tools are used, such as Informatica, Datastage, Microsoft SSIS and so on. These three kinds of tools I have used, the advantages are: graphical interface, development is simple, data flow clear; Disadvantages: limitations, inflexible, It i

Without the tools of hash joins and parallel, MYSQL is destined not to be a suitable data warehousing tool.Whether it is MyISAM or InnoDB, when dealing with a complex SQL query, it is not possible to perform multi-core CPU performance.Only one CPU is running at full load.So for an analytic database, MySQL multicore is actually a huge waste.But after the selection of the scheme, can only do more optimization.For example: Split SQL manually and merge result sets.MY.CNF configuration optimizations,
