Project: De-duplication of Omin-X documents

This project is to DE-duplicate the documents during loading. This

system identifies the duplicate documents, and updates the database schema

with the information about the master document and the duplicate documents.

This information will be used for indexing/Searching module which will

avoid indexing these duplicate documents. This process will increase the

performance of search.

Role: Senior .Net Consultant

. Implementing DeDuplication to filter the duplicate documents during

document load into the OmniX system. The Deduplication process is a

Windows service build on WCF Services on .Net 4.5. During the load,

DPS provides the documents and the docId associated with it to the

Deduplication process. The deduplication process generates SHA1 for

the each document and stores the SHA1 and docId as key-value pair.

Each batch before loading, send list of documents to deduplication

service to check any duplicates exist. If duplicates exist, the

process updates the database with the information about the duplicates

and its master document.

. Performed POC (Proto-typing) on various caching mechanism to store and

retrieve deduplication data quickly to the user. The size is more than

100 Million records. So, did analysis on various data retrieval and

caching mechanisms to make it faster during deduplication retrieval

process. Implemented proto-type code using MemoryCache, Redis and

AppFabric to compare the performances.

Responsibilities:

. Understanding the existing Data load to introduce Deduplication during

the data load.

. Reconfigure existing Node to go thru deduplication process.

. Writing WCF services to expose both SOAP and RESTful API's to

implement Deduplication

. Writing Unit test and performing code reviews using VS2013.

. Responsible for branching and merging using TFS 2013

. Writing Functional tests and do code coverage more than 90%.
