Overview DataStage ETI*Solution Informatica OWB & ODI Others Pentaho Talend


Even after consulting and tuning are employed, big data volumes (i.e., more than one million rows) can be slow to transform, particularly without an expensive hardware or version upgrade of Talend.

Big data bottlenecks are large sorts, joins, aggregations, loads, and sometimes unloads. Parallelization or optimization in other layers or tools can be unwieldy, if not expensive, and may adversely affect performance for other users.

From a security standpoint, Talend may not provide the data discovery, classification, or masking functions, or test data capabilities that data governance officials and application developers need.


Speed Talend Transforms

Speed sorts, joins, and aggregations in a single pass by using CoSort Sort Control Language (SortCL). Run large data transformations without encumbering other jobs in Talend, your database, or BI tool. Also, specify file-format and data-type conversions, field-level masking functions, custom reports, and pre-sorted load files.

Improve the performance of Talend by calling a CoSort SortCL job via tSystem to speed and combine your transformation and other big data staging jobs in much less time and memory space. See this article on relative benchmarks and recommendations.

Mask PII in Talend

Data at rest in tables and flat files within Talend can be sensitive, containing personally identifiable information that is subject to confidentiality restrictions and data privacy laws. Both IRI Voracity and IRI FieldShield can protect fields in structured datasets in any ODBC-connected database or flat-file format.

Your business rules dictate the feature you choose to apply to each column; i.e. format-preserving AES-256, FIPS-compliant OpenSSL, 3DES, and/or GPG encryption, lookup-value substitution (pseudonymization), character masking, hashing, redaction, custom expression logic, substring, or user field function.

Build Talend Test Data

IRI Voracity through its constituent (or standalone) IRI RowGen software product generates safe, realistic test data using COBOL or CoSort metadata, and any RDB data models connected through JDBC. Use RowGen to create compliant, realistic test data from random generation and/or set-file selection, and customize it even further with built-in data manipulation and formatting functionality.

Re-Platform Talend Jobs

Facilitate migration from Talend to faster, simpler ETL operations in IRI Voracity using AnalytiX DS (ADS) Mapping Manager or Code-Automation Frameworks (CATfx). This proven technology, as well as ADS Lite Speed Conversion services, finally gives ETL architects and the CIO/CFO suite the ability to save money immediately and shift to a low-cost operational expense going forward.
