PaimonTableProvider

Struct PaimonTableProvider 

Source
pub struct PaimonTableProvider { /* private fields */ }
Expand description

Read-only table provider for a Paimon table.

Supports full table scan, column projection, and predicate pushdown for planning. Partition predicates prune splits eagerly, while supported non-partition data predicates may also be reused by the Parquet read path for row-group pruning and partial decode-time filtering.

DataFusion still treats pushed filters as inexact because unsupported predicates and non-Parquet reads remain residual filters.
