Enum MaterializeMode 

pub enum MaterializeMode {
    Stream,
    Collect,
}

How model SQL results are written to the lake.

Default is stream: execute_stream → batch write → drop batch (no full Vec<RecordBatch> retention). Use collect only for debugging / emergency.

Variants

Stream

Pull DataFusion stream batch-by-batch; atomic publish; bounded peak RAM.

Collect

DataFrame::collect then write (legacy; holds full result in RAM).
