mirai vs pharmaversesdtm: 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 pharmaversesdtm?
pharmaversesdtm is the test-data layer every pharmaverse package now builds against.
The package ships example SDTM datasets and has grown one therapeutic area at a time — ophthalmology, oncology response criteria, vaccines, metabolic, neurology, and now lymphoma under Lugano 2014. Sibling packages keep moving their internal test data here, so its release notes double as a record of what the rest of the pharmaverse is building.

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.
pharmaversesdtm
0.0ANALYTICS
pharmaversesdtm is the test-data layer every pharmaverse package now builds against.
◆ Current state
The package ships example SDTM datasets and has grown one therapeutic area at a time — ophthalmology, oncology response criteria, vaccines, metabolic, neurology, and now lymphoma under Lugano 2014. Sibling packages keep moving their internal test data here, so its release notes double as a record of what the rest of the pharmaverse is building.
◆ Where it's heading
Two kinds of work alternate: adding domains and biomarkers for a new indication, and making the existing data easier to reach — CSV copies under inst/extdata for non-R programmers, a datasets preview vignette, reference pages categorised by therapeutic area, variable-by-variable breakdowns. Consistency fixes against CDISC terminology and SDTM guidelines run through every release.
◆ Prediction
New therapeutic areas will keep arriving in step with the admiral extension packages that need them; the neurology and metabolic datasets landed just ahead of admiralneuro and admiralmetabolic needing them, and lymphoma looks like the next in that sequence.
