## Summary Follow-up to the Mermaid brand-theming PR, addressing review feedback: - Diagram text was hard to read at the previous 15px font size; bumped to 18px, light and dark alike. - The dark-mode orange accent border was brighter and more saturated than its fill or the default border, reading as too loud against the dark background. It now reuses the same muted orange already used for the light-mode accent border, which was fine as is. ## Companion change lancedb/sophon#9719 makes the same two changes across its own diagrams.

A [computed column](/feature-engineering/add-computed-column) or
|
|
[materialized view](/feature-engineering/materialized-views) filled by a
|
|
registered [Function](/curation/create-function) with `gpu=True` refreshes
|
|
through the exact same placement path as
|
|
[GPU Function execution](/curation/gpu-function-execution) in Data
|
|
Curation -- refreshing a column is not a separate scheduling code path
|
|
from calling the Function directly, just a different caller.

The Function's `gpu_class` (or the deployment's `default`) resolves to the
|
|
same node selector, tolerations and resource name either way, and a
|
|
refresh that needs more GPU capacity than is currently free waits the
|
|
same way a direct call would -- see
|
|
[Waiting for capacity](/curation/gpu-function-execution#capacity) for that
|
|
behavior in full. [Adaptive Execution](/enterprise/adaptive-execution)'s
|
|
resource-consumption-based sizing applies here too: a refresh's GPU
|
|
utilization is measured and fed back into sizing the *next* part the same
|
|
way CPU and memory are.
|
|
|
|
A single refresh can also override the Function's registered placement for
|
|
that run -- see
|
|
[Configure workers and resources](/feature-engineering/refresh-column#resources)
|
|
for the `gpu_class`/`gpu_count` options on `refresh_column_async` and the
|
|
equivalent SQL `WITH (...)` clause.
