Examples with LocalExchangeFactory io.trino.operator.exchange.LocalExchange.LocalExchangeFactory used on opensource projects

Example 1 with LocalExchangeFactory

use of io.trino.operator.exchange.LocalExchange.LocalExchangeFactory in project trino by trinodb.

the class TestLocalExchange method testMismatchedExecutionStrategy.

@Test

    // If sink/source didn't create a matching set of exchanges, operators will block forever,
    // waiting for the other half that will never show up.
    // The most common reason of mismatch is when one of sink/source created the wrong kind of local exchange.
    // In such case, we want to fail loudly.
