  2. Appropriate IAM permissions for the AWS services used

Step 1: Creating table"; aws dynamodb create-table --table-name "$T" --key-schema AttributeName=pk,KeyType=HASH --attribute-definitions AttributeName=pk,AttributeType=S --billing-mode PAY_PER_REQUEST > /dev/null; aws dynamodb wait table-exists --table-name "$T

The script handles this step automatically. See dynamodb-batch-ops.sh for the exact CLI commands.

Step 2: Batch write (25 items)"; aws dynamodb batch-write-item --request-items "{"$T":[$(for i in $(seq 1 25); do echo -n "{"PutRequest":{"Item":{"pk":{"S":"item-$i"},"data":{"S":"value-$i"}}}}"; [ $i -lt 25 ] && echo -n ","; done)]}

The script handles this step automatically. See dynamodb-batch-ops.sh for the exact CLI commands.

Step 3: Batch get (5 items)"; aws dynamodb batch-get-item --request-items "{"$T":{"Keys":[{"pk":{"S":"item-1"}},{"pk":{"S":"item-5"}},{"pk":{"S":"item-10"}},{"pk":{"S":"item-15"}},{"pk":{"S":"item-20"}}]}}" --query "Responses."$T"[].{pk:pk.S,data:data.S}

The script handles this step automatically. See dynamodb-batch-ops.sh for the exact CLI commands.

Step 4: Scan count"; aws dynamodb scan --table-name "$T

The script handles this step automatically. See dynamodb-batch-ops.sh for the exact CLI commands.
