StaticFrame: An Immutable Alternative to Pandas
summary
StaticFrame is an explicit Python 3 wrapper around numpy that enforces immutable numpy arrays and immutable Series/Frame objects, offers a frame_geo grow-only class for appending columns, and provides many specialized iterators with built‑in concurrency for function application. It ships with a May 2018 release, depends only on numpy, and is alpha: some workloads beat pandas (concatenation and subset ops), some are worse — e.g. CSV load measured 113s vs pandas 7–8s — so it works but needs I/O and performance tuning.
