In the Iceberg code repository, the following catalog implementations are included.
Catalog implementation | Data file I/O | Metadata/Management data |
AWS | Amazon S3 | Amazon Glue |
Apache Hadoop | Apache HDFS | Apache HDFS |
Apache Hive | Apache HDFS | Hive Metadata Store |
Project Nessie | Apache HDFS | Project Nessie |
These catalog implementations depend on other components like HDFS. As the role of storage in data lakes becomes more important, we aim to provide a complete set of catalog implementations based on the storage. This section compares ECS to HDFS and shows how we use ECS to build a data lake.
