Error: DynamoDB TTL Not Working
Answered by Rafal Wilinski
What's Causing This Error
There are multiple reasons that may cause TTL not to work. The first cause is TTL being disabled on the DynamoDB table.
The other causes are:
- Using an invalid data type for the TTL attribute.
- When the item does not contain the TTL attribute.
- Using an invalid time format for the TTL timestamp.
Solution: Here's How To Resolve It
As the first step, check and confirm that TTL is enabled for the DynamoDB table. After that, address the other causes individually to see which works for you.
- You can verify whether you have used the same TTL attribute on the items similar to when creating the table with TTL.
- Ensure the type of the TTL attribute is number.
- Verify you have used the UNIX Epoch Time Format for the TTL timestamp.
