Partitions

Last updated 5 months ago

The Partitions tab provides insights into the top 100 largest partitions in the table, helping you analyze and manage data distribution effectively.

Iceberg's schema evolution capabilities allow partition specifications to evolve over time. Partitions created using an older partition specification will no longer receive new data, but they remain visible in the list as long as they are retained in storage. These partitions are marked with an Historical icon to distinguish them.

For each partition, you can track the following statistics:

Metric
Description

Partition

The name of the partition.

Avg.File Size

The average size of data files within the partition.

Total Files

The total number of data files in the partition.

Uncompacted Files

The number of files in the partition that have not been compacted.

Partition Size

The current size of the partition.

Projected Partition Size

The projected size of the partition after compaction is complete.

Current Scan Overhead

The current request overhead by S3 API calls in order to fully scan the partition.

Projected Scan Overhead

The projected request overhead by S3 API calls to scan the partition after compaction is complete.
