the AQP filters out duplicated items

[nwheeler81]

the DDB connector ignores duplicated items, for example,

Input:
{"col2": 1, "col0": "0", "col1": "0"}
{"col2": 1, "col0": "0", "col1": "0"}
{"col2": 1, "col0": "0", "col1": "0"}
{"col2": 1, "col0": "0", "col1": "0"}
{"col2": 1, "col0": "0", "col1": "0"}
{"col2": 1, "col0": "0", "col1": "0"}
{"col2": 1, "col0": "0", "col1": "0"}

Output:
"response": [
{
"resultSet": [
{
"cnt": 1
}
]
}
]
