Under the hood, DynamoDB uses a complex combination of ExpressionAttributeValues, UpdateExpression and Key parameters to update selected parameters of an item. Thanks to Dynobase, it's much easier.

Frequently Asked Questions

Can you update primary key in DynamoDB?

Theoretically, no. You need to create a new item and delete the old one. In Dynobase, if you try to do that, it will handle that process for you automatically.

How long does it take to update DynamoDB item?

It's instant once you commit your save.

How to update a list in DynamoDB?

Unfortunately, in DynamoDB there's no SQL-like 'UPDATE X WHERE Y' expression. You need to call update operation on a set of items one by one.

If I wanted to update DynamoDB items programmatically, how can I do that?

We've created DynamoDB update item query example for all the major languages, you can find them in our DynamoDB Query Examples page.
