Delta Lake vs haven
A side-by-side editorial comparison of Delta Lake and haven — release velocity, themes, recent moves, and the top alternatives to consider.
Delta Lake vs haven: at a glance
What is Delta Lake?
Delta Lake's public releases are patch work while Databricks kernel builds fill the feed.
Two kinds of entry dominate: numbered patch releases on the 3.3 and 4.3 lines, and near-daily Databricks kernel build tags that carry a single commit message each. The patch releases are targeted correctness work — a metadata cleanup that could delete transaction log files still needed to reconstruct versions inside the retention window, a Delta Sharing cache refresh that dropped deletion-vector URL mappings, an OAuth key-casing bug in the REST Catalog, and S3A fast-listing through FilterFileSystem wrappers. The 3.3.3 release also declines to publish delta-iceberg, leaving UniForm users on the prior patch.
What is haven?
haven's release cadence has narrowed to compiler and R-devel upkeep.
haven is the tidyverse's bridge to SPSS, Stata and SAS files, wrapping the C ReadStat library. The last several releases are almost entirely maintenance: syncing vendored ReadStat and patching ahead of R-devel changes. The most recent substantive user-facing work landed in 2.5.2 and earlier.

Two kinds of entry dominate: numbered patch releases on the 3.3 and 4.3 lines, and near-daily Databricks kernel build tags that carry a single commit message each. The patch releases are targeted correctness work — a metadata cleanup that could delete transaction log files still needed to reconstruct versions inside the retention window, a Delta Sharing cache refresh that dropped deletion-vector URL mappings, an OAuth key-casing bug in the REST Catalog, and S3A fast-listing through FilterFileSystem wrappers. The 3.3.3 release also declines to publish delta-iceberg, leaving UniForm users on the prior patch.
◆ Where it's heading
The project is stabilising two supported lines in parallel rather than moving the format forward in these entries, and the recurring theme is metadata and log durability — the parts of Delta that silently break time travel and CDF when they are wrong. Kernel work continues in the build tags, most visibly treating _last_checkpoint as opaque JSON. The unpublished UniForm artifact is the one open thread with a stated follow-up plan.
◆ Prediction
A follow-up patch that restores the delta-iceberg artifact for the 3.3 line is the clearest next step; otherwise expect the kernel build cadence to continue between numbered releases.
haven
0.0ANALYTICS
haven's release cadence has narrowed to compiler and R-devel upkeep.
◆ Current state
haven is the tidyverse's bridge to SPSS, Stata and SAS files, wrapping the C ReadStat library. The last several releases are almost entirely maintenance: syncing vendored ReadStat and patching ahead of R-devel changes. The most recent substantive user-facing work landed in 2.5.2 and earlier.
◆ Where it's heading
Development has shifted from extending the file-format surface to keeping a C dependency compiling against newer toolchains. The deprecation of write_sas() narrowed that surface deliberately, steering users to write_xpt() because the sas7bdat format is undocumented and unsupported upstream.
◆ Prediction
Expect further ReadStat sync releases triggered by compiler or R-devel breakage rather than new format support or writing features.
