If you are working within the Apache Spark ecosystem you can us DeltaLake https://delta.io/ to create 'merge' datasets which are transactional, versioned and allow time travel by both version number and timestamp.

Another alternative to Deltalake is Apache Hudi, which also includes bloom filters for indexing time-travel queries (efficiently exclude any files given the supplied time constraint). Z-ordered indexing in Deltalake is not available yet in open-source deltalake, only in Databricks version.
