admiraldiscovery vs mirai: at a glance
What is admiraldiscovery?
A lookup index for the admiral family that grows one therapeutic area at a time.
admiraldiscovery is a search aid rather than a code package: it maps ADaM variables to the {admiral} functions that derive them, alongside a listing of conference presentations. Its releases are catalogue updates, not functional changes. The most recent adds variables from {admiralneuro} plus AAGE and NFRLT.
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.

◆ Current state
admiraldiscovery is a search aid rather than a code package: it maps ADaM variables to the {admiral} functions that derive them, alongside a listing of conference presentations. Its releases are catalogue updates, not functional changes. The most recent adds variables from {admiralneuro} plus AAGE and NFRLT.
◆ Where it's heading
Each release absorbs the variable listing of whichever therapeutic-area extension shipped most recently — paediatrics in 0.3.0, metabolic in 0.4.0, neuro in 0.6.0. The package is effectively an index trailing the family's expansion, so its cadence is a proxy for how fast new admiral extensions appear.
◆ Prediction
The next release will most likely fold in variables from whichever admiral therapeutic-area package lands next, together with a refreshed presentation list.
mirai
2.5ANALYTICS
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.
