use_iceberg_manifest_list_partition_pruning

Skip whole Iceberg manifest files whose partition summaries in the manifest list cannot match the query filter, without reading them. Requires use_iceberg_partition_pruning to be enabled and only helps when a manifest file holds few distinct partition values, which is what rewriteManifests clustered by the partition columns produces.

​
use_iceberg_manifest_statistics

Estimate the rows of an Iceberg read for join reordering from the record_count of the data files in its manifest files, after partition and min-max pruning by the query filter, without reading data. The estimate is exact without a filter and without delete files. As for MergeTree tables without column statistics, a filter that prunes no file gives no estimate. Pruning by the filter requires use_iceberg_partition_pruning to be enabled.

​
use_iceberg_metadata_files_cache

If turned on, iceberg table function and iceberg storage may utilize the iceberg metadata files cache. Possible values:
  • 0 - Disabled
  • 1 - Enabled
