mirai vs sivirep
A side-by-side editorial comparison of mirai and sivirep — release velocity, themes, recent moves, and the top alternatives to consider.
mirai vs sivirep: at a glance
What is mirai?
mirai removed its dispatcher process and added memory backpressure to the queue.
The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.
What is sivirep?
sivirep turned Colombia's SIVIGILA surveillance data into a one-call reporting package.
The 1.0.0 release of December 2024 is the substance of this feed: incidence calculation and plotting for the country, departments and municipalities, ethnicity and case-classification breakdowns, multi-year retrospectives, and a Reporte Evento template that assembles them. It was shaped by usability testing and expert review with Colombia's National Institute of Health. The two patches since are fixes, warnings and documentation.

mirai removed its dispatcher process and added memory backpressure to the queue.
◆ Current state
The async evaluation framework releases roughly monthly and moves fast at the architecture level. In 2.7.0 the dispatcher stopped being a separate process and became a thread, after its loop had already been rewritten in C inside nanonext one release earlier. The same release added an opt-in memory budget for queued task payloads and try_mirai(), which returns NULL immediately rather than blocking when that budget is exhausted.
◆ Where it's heading
Two threads of work run together: cutting overhead out of the task path — thread-based dispatcher, in-process transport for synchronous daemons, lower per-element dispatch cost in mirai_map() — and making the framework safe to embed in an event loop, where blocking the host R thread is not acceptable. Deployment reach is growing too, with http_config() launching remote daemons over HTTP APIs and auto-configuring for Posit Workbench. Each release pins a minimum nanonext version, so the two packages advance as one unit.
◆ Prediction
With backpressure in place but opt-in, the open question these notes leave is whether a default memory budget arrives; continued overhead reduction and Shiny-facing non-blocking paths are the safer bet.
sivirep
0.0ANALYTICS
sivirep turned Colombia's SIVIGILA surveillance data into a one-call reporting package.
◆ Current state
The 1.0.0 release of December 2024 is the substance of this feed: incidence calculation and plotting for the country, departments and municipalities, ethnicity and case-classification breakdowns, multi-year retrospectives, and a Reporte Evento template that assembles them. It was shaped by usability testing and expert review with Colombia's National Institute of Health. The two patches since are fixes, warnings and documentation.
◆ Where it's heading
Work after 1.0.0 has gone into making the report template survive bad input rather than adding analyses — warnings when a municipality or department has no data, handlers that surface import and geo-filter errors during rendering, and an explicit note that first use of any import function needs an internet connection. English-language articles were added alongside the Spanish function interface.
◆ Prediction
Spanish-named functions paired with new English articles point at a widening audience; more translation of the guides looks likelier than new epidemiological methods.
