Fast ETL Is Affordable
Go Beyond Legacy ETL Tools with Voracity
In ETL (extract, transform, load) operations, data are extracted from different sources, transformed separately, and loaded to a data warehouse (DW) database and possibly other targets.
Those weaknesses are all the more glaring when compared with the IRI Voracity data management platform.
Big Data: Rapid Acquisition
IRI supports a variety of high-performance extraction methods for static files and streaming data. Pump data in memory through pipes or procedures, web services, IoT devices, Kafka, and more.
VLDB Unloading: ODBC Select or "Fast Extract"
Very large database (VLDB) tables require a high-performance unloading (extraction) method for:
- Data warehouse ETL and ELT operations
- Classic (offline) reorgs
- Archival and storage
- Migration and replication
- Data interchange
IRI Voracity, as well as its component products IRI CoSort (for data transformation and reporting) and IRI NextForm (for data and database migration), reads data directly from relational and NoSQL DBs via ODBC or native protocols. Or, you can dump huge RDB tables in parallel to flat files using IRI FACT (Fast Extract).
Extraction performance in DB and DW environments is constrained by high data volumes and inefficient approaches. Read about a remedy for big Oracle tables in this blog post.
Source-side selection in IRI CoSort via SQL and filtering commands in the CoSort SortCL program -- as well as change data capture ( CDC) scripts -- can improve acquisition performance by reducing data bulk. SortCL supports any number of input tables, files, pipes, and procedures at once, and can apply specific filtering criteria for each data source.
You can also extract values from structured and unstructured document sources into flat files, based on searches for literal strings and Java regular expressions (patterns). Multiple data discovery wizards, which also profile such sources, exist in the IRI Workbench GUI, to help you find and use dark data.
For VLDB data acquisition, IRI FACT (Fast Extract) uses native drivers and parallel query methods to turn VLBD tables into flat files when bulk unloads are needed. FACT imposes no database overhead or configuration changes. FACT also bypasses the need to set up log sniffers and complex CDC in the database.
FACT uses SQL SELECT syntax in simple configuration files to unload data from: Oracle, DB2 UDB, Sybase, MS SQL Server, MySQL, Altibase, and Tibero.
During extraction, FACT reformats (e.g. delimiter) and converts the data (e.g. date types), and silos LOB fields. FACT also writes CoSort SortCL metadata for data transformation, conversion/replication, masking, and reporting, plus loader control file metadata for the source databases. This facilitates reorgs and ETL in the same I/O pass.
The IRI Workbench GUI for FACT, CoSort, etc. supports the automatic creation of tables and loader files for additional target databases including Teradata - in Eclipse.
Optimize Each Transform
Voracity accelerates every essential data transformation process. It also optimizes ETL operations by combining sorts, joins, and aggregations in a single job script, partition, and I/O pass.
With Voracity, you can transform massive volumes of data without using your DB and without Hadoop, NoSQL, or an ELT appliance. Beat the steep learning curves of other tools with its easily understood, shared, and modified data and job definitions.
Voracity has everything you need to transform data faster and more effectively.
Combine Multiple Transformations
Voracity enables you to leverage multiple CPUs and cores, execute multiple tasks in the same I/O, and dynamically allocate resources. Transform large data volumes from many different table and sources together. Simple text file metadata repositories, which you can manage in the free IRI Workbench GUI built on Eclipse™, allow you to discover, defined, and expose your data. To learn more about how IRI Voracity can maximize your data transformations, see the Data Transformation section.
If the fastest place to stage a data warehouse database (DB) is in the file system, what is the fastest way to load them? There are many ways to load DBs, including:
- single or bulk row inserts
- create or insert (with append hint) as select from another table
- conventional and direct path loads
Many DBAs do not know the fastest method, and instead use proprietary export/import tools that tax their databases and do not serve heterogeneous data warehouse architectures.
The CoSort data transformation phase of Voracity jobs can rapidly sort flat files in index order that RDB load utilities can rapidly pump into tables while bypassing slower, DB-taxing internal sorts. Having tables in order, and removing bulk transformation overhead from the DB layer, both improve query performance.
The IRI Voracity total data management platform combines FACT, CoSort, and bulk DB load utilities in a visualized, scheduled ETL workflow that does not require compilation or partitioning. It can even seamlessly run CoSort jobs in MapReduce, Spark, Storm, or Tez instead.
Compare all this to slower, more verbose SQL and 3GL programs, and to costlier, more complex ETL and ELT platforms ... not to mention the onboarding delays of disjointed Apache projects.
ETL metadata and job definition are automated in the IRI Workbench GUI for Voracity, built on Eclipse™. Data discovery and new job wizards, and a number of visual ETL job design options, speed-build reusable repositories and scripts without requiring an education in new syntax.
Nevertheless, Voracity metadata is the easiest in the IT industry to learn and use. It uses the same human-readable 4GL of CoSort -- called SortCL -- that leverages familiar data layout syntax, SQL manipulation concepts, and shared metadata repositories. Many users still prefer to code and tweak these simple scripts directly.

Voracity supports these activities on a very broad range of structured, legacy, big data, cloud and SaaS data sources.
Create all the E, T, and L jobs in the IRI Workbench GUI for Voracity, built on Eclipse™. Edit the jobs or workflow in palettes, GUI dialogs, syntax-aware script editors (or any text editor you prefer), or the AnalytiX DS Mapping Manager. You have the ergonomic flexibility of working the data definitions and manipulations visually or through scripting; anything done in one feeds the other.
Test or run jobs individually or together in the GUI flow, or later in a (scheduled) batch operation. You have that execution flexibility because the job scripts are portable. You can run any of the pieces, or the whole project, on any platform where the engine(s) are licensed. Call them from the command line or any application.
The IRI Workbench GUI for Voracity delivers the visual metadata creation, conversion, and discovery tools you need to generate, deploy, and manage the job scripts, data definition files (DDF), and XML workflows common to all IRI software.
In the same place, you can also design and run COBOL, C/C++, Hive, Impala, Java, Perl, Python, R, SQL, and other programs supported in Eclipse, and sometimes incorporate them as steps in your Voracity workflow.
Voracity is far more than an ETL tool, yet is priced below most of them. Even if you don't use it for ETL, because its SortCL program can join across many sources and query data in flat files, Voracity continues in the CoSort tradition as one of the least expensive change data capture, and NoSQL query paradigms available.
For serious ETL architects however, Voracity's consolidation and multi-processing of transformations in the file system or (seamlessly in) Hadoop makes it the most cost-effective big data processing alternative to DB/ELT appliances, Ab Initio, SyncSort, Teradata, and in-memory DBs.
Finally, with its freemium editions, low-cost opex subscription tiers, and relative simplicity, Voracity is the most affordable data management platform to on-board and maintain.
