A side-by-side editorial comparison of filearray and wasserportal — release velocity, themes, recent moves, and the top alternatives to consider.
filearray vs wasserportal: at a glance
What is filearray?
The on-disk array layer under RAVE spends its releases hunting segfaults.
filearray stores large arrays on disk and reads them back with little memory overhead, serving as the storage substrate for the RAVE intracranial EEG stack. The 0.2.2 release fixes out-of-bound indexing that caused segfaults along certain margins and an ASAN-flagged signed integer overflow in the load path. The user-facing API has been stable since 0.1.6.
What is wasserportal?
A Berlin groundwater scraper grew a full IoT publishing pipeline in two days.
wasserportal scrapes groundwater and surface water monitoring data from Wasserportal Berlin — station metadata, water levels, quality series. For its first four years that was the whole product, with releases tracking the portal's own churn: a new API version in 2023, new three-letter variable codes, and a 2026 fix decoding pages as windows-1252 because the server declares UTF-8 but emits Latin-1. In June 2026 it added a ThingsBoard integration, then extended it to self-hosted instances two days later.

The on-disk array layer under RAVE spends its releases hunting segfaults.
◆ Current state
filearray stores large arrays on disk and reads them back with little memory overhead, serving as the storage substrate for the RAVE intracranial EEG stack. The 0.2.2 release fixes out-of-bound indexing that caused segfaults along certain margins and an ASAN-flagged signed integer overflow in the load path. The user-facing API has been stable since 0.1.6.
◆ Where it's heading
This is infrastructure whose release history reads as a memory-safety log: unprotected C++ variables, buffer sizes exceeding array length, allocations one byte short, endianness on big-endian platforms, and now out-of-bound margins caught by sanitizers. The one sustained feature direction is reducing the cost of operating on arrays too large for memory — lazy operator evaluation through a proxy class, fmap-style application, and marginal collapse. Portability work has steadily removed hard requirements, dropping the C++11 declaration and swapping OpenMP for TinyThreads to get parallelism on macOS.
◆ Prediction
Expect continued sanitizer-driven patches rather than new interfaces; the three-year gap before 0.2.2 suggests releases now arrive only when a crash or a CRAN check demands one.
wasserportal
0.0ANALYTICS
A Berlin groundwater scraper grew a full IoT publishing pipeline in two days.
◆ Current state
wasserportal scrapes groundwater and surface water monitoring data from Wasserportal Berlin — station metadata, water levels, quality series. For its first four years that was the whole product, with releases tracking the portal's own churn: a new API version in 2023, new three-letter variable codes, and a 2026 fix decoding pages as windows-1252 because the server declares UTF-8 but emits Latin-1. In June 2026 it added a ThingsBoard integration, then extended it to self-hosted instances two days later.
◆ Where it's heading
The package is repositioning from a data-access library into the first half of a monitoring pipeline. 0.6.0 shipped push helpers, device discovery and cleanup, an importable dashboard and a GitHub Actions workflow; 0.7.0 immediately generalised the authentication so it works against self-hosted Community Edition rather than only the Cloud tier, and lifted the push from a five-station demo to the entire groundwater archive. The hardening detail in 0.7.0 — retries on 5xx, warnings when only one of two credentials is set — reads like a maintainer who has run this against a real deployment.
◆ Prediction
The obvious next step is extending the ThingsBoard path to the surface water stations, which the package has flagged as under-supported since 0.1.0. The entries show no other direction under construction.
