Error: why is the GSI dynamodb not showing item count
Answered by Rafal Wilinski
What's Causing This Error
DynamoDB updates the item count of a GSI roughly every 6 hours. Therefore, it will take a while for DynamoDB to update the item count if you added them recently.
Consequently, you will not be able to see the item count for a few hours (approximately 6).
Solution - Here's How To Resolve It
There is no way to improve the time taken for DynamoDB to count items in the GSI. Hence, the only solution is to wait for a couple of hours before checking the item count.
