I have been using BigQuery for over 2 years now at Shine. I've found it to be a great tool that is both incredibly fast and able to handle some of our largest workloads. We are processing terabytes of data per day, and each day an extra billion records are added to the store. But unfortunately this growth is also increasing our costs of running queries. While BigQuery is extremely fast and parallel, it comes at the cost of needing to scan and pay for every record of the columns you are querying. Without the indexes offered by conventional databases, a full table scan is needed for each query. Not only that but when you query large amounts of data the speed of your query slows down:In this post I'll talk about how we used table partitions to increase the performance of our queries and avoid query slowdowns.
Databases are the backbone of most modern web applications and their performance plays a major role in user experience. Faster response times - even by a fraction of a second - can be the major deciding factor for most users to choose one option over another. Therefore, it is important to take response rate into consideration whilst designing your databases in order to provide the best possible performance. In this article, I’m going to discuss how to optimise DynamoDB database performance by using partitions.
