Inserting and Hosting 551 Millions Records Cheaply - Case Study

Recently I worked on a pet project with cloud implementation. There was a dump file in text format with 551 million line of records which needs to be stored in a way where filtered results could be quickly returned from a query, and with a goal of low cost implementation.

The dataset is static. Large number of records. No relational requirement. The storage and querying has to be fast and low cost. Azure table storage seems to be a good candidate for this purpose. Azure table storage is a NoSQL key value store and is very cheap.

Query Hint and Plan Guide

Query execution plan generated for a SQL query significantly affect the query performance. Parameter sniffing, indexes, statistics and other factors are taken into consideration for SQL Server query optimizer to produce an optimal query plan for the execution within a timely manner.
