Frequently Asked Questions
Can you update item's 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. The API operation completes usually in less than 100ms.
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.
Can I update multiple items at once?
Sure! In Dynobase, you update multiple items and save them to the database at once. The modified items will be saved to the table only after you'll press 'Save Changes'. If you want to do so programmatically, head to our guide on batchWrite operation
