Struct CowBatchRewrite 

Source 
pub struct CowBatchRewrite {
    pub output: Option<RecordBatch>,
    pub changed: bool,
}
Expand description

Result of rewriting a single record batch.

Fields§

§output: Option<RecordBatch>

Rewritten output batch, or None when the input batch is fully removed.

Output batches must use the same schema as their input batch — the planned snapshot’s schema, which may be older than the table’s current schema. Rewriters must also preserve each source file’s partition values: this primitive writes replacements into the source file’s partition and does not repartition rows.

§changed: bool

Whether the rewrite changed the input batch contents.

Set this to true whenever output differs from the input batch, including filtered rows, updated values, reordered rows, or None.
