    Functions functions = new ModulesBuilder().add(new AggregationImplModule()).createInjector().getInstance(Functions.class);
    SumAggregation<?> sumAggregation = (SumAggregation<?>) functions.getQualified(Signature.aggregate(SumAggregation.NAME, DataTypes.INTEGER.getTypeSignature(), DataTypes.LONG.getTypeSignature()), List.of(DataTypes.INTEGER), DataTypes.INTEGER);
    var memoryManager = new OnHeapMemoryManager(bytes -> {
    });
    collector = new AggregateCollector(Collections.singletonList(inExpr0), RamAccounting.NO_ACCOUNTING, memoryManager, Version.CURRENT, AggregateMode.ITER_FINAL, new AggregationFunction[] { sumAggregation }, Version.CURRENT, new Input[][] { { inExpr0 } }, new Input[] { Literal.BOOLEAN_TRUE });
}
