Confidential

NoSql SME

Responsibilities:

• Define architecture required for POC/role out - Design data architecture (data model) for local implementation or deployment on HDFS distributed multi-node node Cloudera Cluster
• Worked on data modeling and data import and export. Extensive experience in deploying, managing and developing MongoDB clusters. Experience in creating JavaScript for using DML operation with MongoDB .
• Creation, configuration and monitoring Shards sets. Analysis of the data to be shared, choosing a shard Key to distribute data evenly. Architecture and Capacity planning for Mongo DB clusters. Implemented scripts for mongo DB import, export, dump and restore.
• Worked on MongoDB database concepts such as locking, transactions, indexes, Sharding, replication, schema design. Created multiple databases with sharded collections and choosing shard key based on the requirements. Experience in managing MongoDB environment from availability, performance and scalability perspectives.
• Worked on creating various types of indexes on different collections to get good performance in Mongo database.
• Worked on creating documents in Mongo database.
• Worked on multiple BSON type objects and used based on requirement.
• The same product is tested with CouchBase as the main database and created new architecture for the same product. In this architecture we have used concept of the autosych between Databases to ease the synchronization of the data between the databses.
• The same product is tested with Cassandra as the main database and created new architecture for the same product. In this approach we used 3 data center approach.i.e writes are directed to first data center and reads are directed 2 and 3 data center.
• The same product is tested with in memory databases such as VoltDB and memSQL as the main database and created new architecture for the same product. In this architecture we have used concept called streaming table so that data can be directly stored in the tables rather than using the some streaming mechanism.
