Struct MergeTxLimits 

pub struct MergeTxLimits {
    pub max_rows: usize,
    pub max_bytes: usize,
}

Hard materialization limits for one merge transaction.

Enforced on the writer connection inside the merge’s own BEGIN IMMEDIATE transaction, so the counted rows are exactly the rows the merge operates on — a pre-flight count on another connection could be outgrown between the count and the merge. Exceeding either limit rejects the merge with the observed counts before further state is materialized, and the transaction rolls back. Dry runs are budgeted identically: the preview performs the same reads and carries the same materialization hazard.
