IcebergOptimizationProperties
A structure that specifies Iceberg table optimization properties for the catalog, including configurations for compaction, retention, and orphan file deletion operations.
Contents
- Compaction
-
A map of key-value pairs that specify configuration parameters for Iceberg table compaction operations, which optimize the layout of data files to improve query performance.
Type: String to string map
Key Length Constraints: Minimum length of 1. Maximum length of 255.
Key Pattern:
[\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*Value Length Constraints: Maximum length of 512000.
Required: No
- OrphanFileDeletion
-
A map of key-value pairs that specify configuration parameters for Iceberg orphan file deletion operations, which identify and remove files that are no longer referenced by the table metadata.
Type: String to string map
Key Length Constraints: Minimum length of 1. Maximum length of 255.
Key Pattern:
[\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*Value Length Constraints: Maximum length of 512000.
Required: No
- Retention
-
A map of key-value pairs that specify configuration parameters for Iceberg table retention operations, which manage the lifecycle of table snapshots to control storage costs.
Type: String to string map
Key Length Constraints: Minimum length of 1. Maximum length of 255.
Key Pattern:
[\u0020-\uD7FF\uE000-\uFFFD\uD800\uDC00-\uDBFF\uDFFF\t]*Value Length Constraints: Maximum length of 512000.
Required: No
- RoleArn
-
The Amazon Resource Name (ARN) of the IAM role that will be assumed to perform Iceberg table optimization operations.
Type: String
Pattern:
^arn:aws(-(cn|us-gov|iso(-[bef])?))?:iam::[0-9]{12}:role/.+Required: No
