Please watch Percona’s Senior Technical Operations Specialist, Tim Vaillancourt, as he presents “How to Improve MongoDB Performance with Proper Queries”.
There are a lot of different ways you can use queries in MongoDB to find the data you need; however, knowing which queries are slowing down your performance can be a challenge. In this webinar we’ll discuss the following:
- How to perform ad-hoc queries on the database using the find or findOne functions and a query document.
- How to query for ranges, set inclusion, inequalities, and more by using $-conditionals.
- How to use and sort queries that return a database cursor, which lazily returns batches of documents as you need them.
- There are a lot of metaoperations you can perform on a cursor, including skipping a certain number of results and limiting the number of results returned. We will also discuss some pitfalls.
By the end of this webinar, you will have a better understanding of which queries impact performance and how to leverage open source tools to monitor queries.
