You must set your TTL attribute as a top level attribute. You cannot have it inside a map:
{
"timestamp": "2022-01-26 13:00:30.676968",
"epoch": 1643230830,
"payload": {
"air_flow": 1.5,
"rssi": -93,
"temp": 19.09,
"data": "03d10775018f0a006ff3",
"rx_freq": 929000000,
"humidity": 28.659,
"ep": 1,
"pressure": 102154,
"seq": 71,
"timestamp": "2022-01-26 13:00:30.676968"
}
}

I made another table, and used epoch as the primary key instead, it did not delete in the preview. I also made it an item in the top level, along side the primary key, it doesn't delete.
You are aware it can take 48 hours. Please provide more details on your table:
The output of:
aws dynamodb describe-time-to-live --table-name <your table name>A sample item which you expected to have been evicted, including the time it was inserted to the table.
output: { "TimeToLiveDescription": { "TimeToLiveStatus": "ENABLED", "AttributeName": "epoch" } } I am aware of the 48 hour period. I was using the "run preview" feature to see what would be deleted in a week, and there are no results in the query.
Don't use the preview...it doesn't seem to work
I encourage you to use the feedback button in the console, it will alert the team responsible for the preview feature.
