The adoption of open table formats is a crucial consideration for organizations looking to optimize their data management practices and extract maximum value from their data. An Iceberg table’s metadata stores a history of snapshots, which are updated with each transaction. In earlier posts, we discussed AWS Glue 5.0 for Apache Spark.

Iceberg tables store metadata in manifest files. As the number of data files increase, the amount of metadata stored in these manifest files also increases, leading to longer query planning time. The query runtime also increases because it’s proportional to the number of data or metadata file read operations.
