⚠️ Breaking change: Reduce coordinator memory usage for the Delta table metadata
cache and enable configuration delta.metadata.cache-max-retained-size to
control memory usage. Remove the configuration property
delta.metadata.cache-size and increase the default for
delta.metadata.cache-ttl to 30m. (#24432)
Enable mismatched bucket execution optimization by default. This can be
disabled with hive.optimize-mismatched-bucket-count configuration property
and the optimize_mismatched_bucket_count session property. (#23432)
Improve performance by deactivating bucket execution when not useful in query
processing. (#23432)
Improve performance when running a join or aggregation on a bucketed table
with bucketed execution. This can be deactivated with the
iceberg.bucket-execution configuration property and the
bucket_execution_enabled session property. (#23432)
Deprecate the iceberg.materialized-views.storage-schema configuration
property. (#24398)
⚠️ Breaking change: Rename the partitions column in the $manifests metadata table
to partition_summaries. (#24103)
Avoid excessive resource usage on coordinator when reading Iceberg system
tables. (#24396)
