Unlocking the Mystery of MongoDB Shard Key Selection

Do You Know How to Choose the Right MongoDB Shard Key for Your Business?

In our upcoming panel, Percona MongoDB experts Mike Grayson, Kimberly Wilkins, and Vinicius Grippa will discuss the complex issue of MongoDB shard key selection and offer advice on the measures to take if things go wrong.

Selecting the right shard key is one of the most important MongoDB design decisions you make, as it impacts performance and data management. Choosing the wrong shard key can have a disastrous effect on both.

MongoDB 5.0 is due to be released this summer, and it is likely to include another big change around sharding. Following last year’s 4.4 release that included refinable shard keys, we expect to see a new feature that allows for fully changeable shard keys for the first time.  

But, even with refinable and changeable options, shard key selection will continue to be a crucial MongoDB task.

Join us for the panel, where Mike, Kimberly, and Vinicius will highlight some of the perils and pitfalls to avoid, as well as offering shard key best practices such as:

• Factors to consider when selecting your shard key
• Hidden “gotcha’s” around shard selection and architecture
• Examples of the worst shard keys our experts have seen
• What happens when you have a busted shard key, and how you can mitigate the impact
• What’s happening “under MongoDB’s hood” with all the changes?
• The future of shard keys for MongoDB
