Error: dynamodb consistent reads are not supported on global secondary indexes

Answered by Rafal Wilinski
What's Causing This Error
DynamoDB global secondary indexes are eventually consistent. So, the changes performed on global secondary indexes will take some time to reflect in other places. In most situations, you will see this error if you try to read data before the index is updated.
Solution: Here's How To Resolve It
There are several things you need to consider when fixing this issue. You can choose one based on your requirement.
- Wait some time until the changes are updated.
- Use local secondary indexes since they have a tighter consistency boundary and are updated more quickly than global secondary indexes.
- Use DynamoDB Streams to track changes for a table in near real-time.
