I want to know item count with DynamoDB querying.

I can querying for DynamoDB, but I only want to know \'total count of item\'.

For example, \'SELECT COUNT(*

Answer 1

With the aws dynamodb cli you can get it via scan as follows:

aws dynamodb scan --table-name  --select "COUNT"

The response will look similar to this:

{
    "Count": 123,
    "ScannedCount": 123,
    "ConsumedCapacity": null
}

notice that this information is in real time in contrast to the describe-table api
