In their own words
Apache Iceberg
Apache Iceberg is a free, open-source table format for analytic datasets, including very large analytic tables. It is self-hosted and works through APIs on Linux, macOS, and Windows, using storage you provide. Engines such as Spark, Trino, Flink, Presto, Hive, and Impala can use the same tables. SQL commands support merging new data, updating rows, and targeted deletes. Columns can be added, renamed, or reordered without rewriting a table. Hidden partitioning creates partition values and skips unnecessary partitions and files. Table snapshots can be queried by version or timestamp, and tables can be rolled back. Atomic updates, serializable isolation, consistent snapshot reads, and optimistic concurrency support multiple writers. Integrations include Kafka Connect and catalogs such as AWS Glue, JDBC, and Nessie. Encryption supports AWS, Azure, or GCP KMS clients, including custom clients. Version 1.12.0 removes Spark 3.4 and Flink 2.0 support. The Apache License 2.0 applies.
DataLad
DataLad is a free, open-source system for managing file-based datasets on Linux, macOS, and Windows. It uses Git and git-annex to version files of any size without custom data structures, central infrastructure, or third-party services. Provenance records support reproducible workflows, and linked datasets can form deeply nested hierarchies managed with recursive commands. Users can work through a graphical interface or command line, with operations to create and clone datasets, retrieve content when needed, save changes, and drop or push content. Built-in export commands support services such as GitHub and Figshare; compatibility also includes Dropbox and Amazon S3. Installation documentation covers Python, datalad-installer, Git, and git-annex. The handbook describes using git-annex with GnuPG to encrypt data during storage and transport, and credentials can be held in the operating system’s encrypted keyring through Python keyring. A privacy caveat is that sensitive information saved in Git remains visible in revision history even after later removal. Help is available through Matrix chat, weekly office hours, and GitHub issues. DataLad and its associated documentation use the MIT license.
