• To get the last compaction run details for a table

  aws get-table-optimizer \
    --catalog-id 123456789012 \
    --database-name iceberg_db \
    --table-name iceberg_table \
    --type compaction                  

• Use the following example to retrieve the history of an optimizer for a specific table.

  aws list-table-optimizer-runs \
    --catalog-id 123456789012 \
    --database-name iceberg_db \
    --table-name iceberg_table \
    --type compaction                   

• The following example shows how to retrieve the optimization run and configuration details for multiple optimizers. You can specify a maximum of 20 optimizers.

  aws glue batch-get-table-optimizer \
  --entries '[{"catalogId":"123456789012", "databaseName":"iceberg_db", "tableName":"iceberg_table", "type":"compaction"}]' 
                   

• Use GetTableOptimizer operation to retrieve the last run details of an optimizer.

• Use ListTableOptimizerRuns operation to retrieve history of a given optimizer on a specific table. You can specify 20 optimizers in a single API call.
