NOT_SUPPORTED

Error message

Filter Pushdown not supported for Iceberg Java Connector

What it means

IcebergPageSourceProvider.createPageSource throws NOT_SUPPORTED when the table layout has filter pushdown enabled (isPushdownFilterEnabled). The Java Iceberg connector does not support pushing filter evaluation down into the page source layer, so the request is rejected rather than silently ignoring the filter.

Solutions

1. Disable the pushdown filter session/config property for Iceberg (e.g. the pushdown_filter_enabled flag) and re-run the query
2. Verify the connector in use; pushdown-based filtering is only valid for the native connector path, not the Java connector
3. If this arises from custom planner code, build IcebergTableLayoutHandle with pushdown filter disabled

Example fix

// before
SET SESSION iceberg.pushdown_filter_enabled = true;
SELECT * FROM iceberg_table WHERE col > 10;
// after
SET SESSION iceberg.pushdown_filter_enabled = false;
SELECT * FROM iceberg_table WHERE col > 10;

IcebergTableLayoutHandle layout = ...;
if (layout.isPushdownFilterEnabled()) {
    // fix configuration before calling createPageSource
    throw new IllegalArgumentException("Disable pushdown_filter for the Iceberg Java connector");
}

When it happens

Trigger: Calling IcebergPageSourceProvider.createPageSource with an IcebergTableLayoutHandle whose isPushdownFilterEnabled() returns true — i.e. the query plan/session enabled pushdown-based filtering for the Iceberg Java connector.

Common situations: A session/config flag for pushdown filter mode was left enabled (e.g. experimental pushdown_filter_enabled) while running queries through the Java connector; a planner integration or custom plugin requests layouts built for the pushdown path.
