Session: Moving at the Speed of Markets
Speaker: Gyan Aggarwal, Triple Point Technology
Description: Our application is a Commodity Trading platform where market data changes very frequently. The actual value change can be in a few columns of only some of the column families but it has a very wide impact in the valuation of trades where most of the relevant columns are computed.

This framework has been developed to implement some of the core functionality of an application that has to process a very large volume of data every day and it also performs some very complex computations. It has to access data from many column families to perform its complex computation. It runs a batch process on very large volume of data and here speed of process is of essence.

Cassandra proved to a natural and cost-effective platform to implement this kind of application. It is natural because it is column-oriented persistent store. Although, it can be daunting task a developer to implement a complex application using Cassandra API. This framework addresses this same issue by encapsulating the Cassandra API complexity into a very simple framework API. This framework also implements one-to-one and one-to-many secondary index column family pattern.
