Winnow is a framework for server-side filtering of data.
Project description
Winnow is a framework for server-side filtering of data. It is designed to be expressive, extensible, and fast. Winnow’s inputs look something like this:
{
"logical_op": "&",
"filter_clauses": [
{
"data_source": "Created",
"operator": "before",
"value": "2015-03-01"
},
{
"data_source": "Owner",
"operator": "any of",
"value": [
{"name": "Steven", "id": 23},
{"name": "Margaret", "id": 41},
{"name": "Evan", "id": 90}
]
}
]
}
Winnow’s outputs look something like this:
"WHERE created_date < %s::timestamp AND owner_id = ANY(VALUES (%s),(%s),(%s))",
('2015-03-01', 23, 41, 90)
