PROFESSIONAL EXPERIENCE:
Confidential
Senior solution architect
Responsibilities:
- Cognos Audit report: Confidential and Confidential being huge infrastructure hosting over 200 servers just for Cognos providing service for over 45,000 report users, The data on report usage is being captured on 5 different servers and 32 different databases. This data is currently being brought together transformed for reporting using Informatica, loading into 385 sql server tables, feeding the Cognos report. This caused delay on several layers, Informatica outage, performance issues due to volume and data issues due to complexity. These issues were resolved using Cloudera Big data solutions. Using sqoop, the data was pumped and using Impala data from 385 tables were consolidated into 12 which tremendously eased the performance and complexity issues.
- Informatica jobs that used to run for hours loading the 385 tables is now being loaded in minutes using Cloudera Hadoop. The changes at the data layer are seamless to the existing reports, so no changes were required at the reporting level.
