CoSort Deep Dive

Sorting is Only the Beginning

The Sort Engine


For four decades, IRI CoSort has defined the state-of-the-art in big data sorting and related manipulation technology. From advanced algorithms to automatic memory management, and from multi-core exploitation to I/O optimization, there is no more proven performer for production data processing than CoSort.


CoSort was the first commercial sort package developed for open systems: CP/M in 1980, MS-DOS in 1982, Unix in 1985, and Windows in 1995. Repeatedly reported to be the fastest commercial-grade sort product for Unix, CoSort was also judged by PC Week to be the "top performing" sort on Windows.


Being the first and fastest are just two reasons why CoSort is "The Open Systems Standard" in sorting technology. For more details on the power of the engine, see details here.


To accelerate your current sort function, or convert from a legacy sort product like SyncSort, to CoSort, see the details about the Sort PlugIns here and about the Sort Migration here.

Data Transformation, Cleansing, and Reporting


For many CoSort users, speed is more than just how many gigabytes they can sort in a minute. It is also about how much data staging, security, and analytic work they can accomplish in the same place and pass through their data. CoSort uses an award-winning, open 4GL program for data definition and transformation called SortCL to perform and consolidate multiple activities.

It is because SortCL can also do all this work at once that it's the default manipulation and mapping program in the IRI Voracity ETL and data management platform.

 For information on the combinable functions in CoSort, check out the SortCL function matrix, or enlarge this diagram:

How many data sources can you transform -- while producing delta, detail, load, and report targets -- all in one job and I/O pass?

This sounds like "super-fast ETL and more" on the cheap. Is it, and can it happen in one product, place, and pass?

Accelerating Applications


CoSort is not only a standalone product for data manipulation and management, but also a "point solution" for speeding these database, DW ETL, and BI/analytic platforms:

  • ETL Tools

    ETI Solution
    IBM DataStage
    Microsoft SSIS
    Oracle Data Integrator
    TalendOpen Studio
  • BI Tools

  • Analytic Tools

  • Databases Tools

    SQL Server

As well as: offline database reorgs, SAS Proc Sort, Software AG Natural, and legacy COBOL programs -- wherever high-volume jobs need more sorting and data transformation speed.


You can also use CoSort sort plug-ins and API calls, or CoSort SortCL programs to prepare (blend) large data sets through selection, sorting, joining and aggregation. The results of CoSort operations routinely feed database load utilities, analytic engines, BI tools and cubes, Excel, and custom applications.

Included: Data Masking and Test Data Creation


For information security and compliance efforts, CoSort can de-identify sensitive data, and thus mitigate the security and governance risks that personally identifiable information (PII) represents. Powerful field-level data encryption and masking functions are built into SortCL.

Transform and protect PII at the same time, and still allow access to your tables, files, and everything around them. Produce an audit trail to verify compliance with data privacy regulations.

SortCL metadata also works in IRI's fit-for-purpose data masking product FieldShield, and test data generator RowGen.
