peQL (Python)
Query data through parcel contracts: every table is a contract, and each caller gets what the contract allows. Python bindings for the peQL engine.
pip install maturin && maturin develop --release # from bindings/python
import peql
import pyarrow as pa
engine = peql.Engine.open("./workspace")
engine.register(open("orders.yaml").read(), schema=orders.schema) # a parcel contract
engine.write("sales/orders", orders) # a pyarrow Table
engine.publish("sales/orders", "globex")
table = engine.query(
'SELECT region, COUNT(*) AS n FROM "sales/orders" GROUP BY region',
peql.Caller("user:bob", "analytics", "globex"),
)
table, envelope = engine.query_with_envelope(sql, caller) # what the contract did
A query the contract refuses raises peql.Refused. engine.validate(name) returns the
verdict; engine.describe(name, caller) the columns a caller would see;
engine.register_bundle(json) registers a bundle from parcel compile -o.
