Limits
Every limit here reports itself rather than failing silently. These are the numbers to plan around.
#Every limit
Limit | Value | What happens |
|---|---|---|
Document title length | - | Enforced by the Title input in the editor. The title becomes the attachment filename. |
Global page results per fetch | - | The Capable Markdown page loads 50 issues at a time; 'Show more' fetches the next page. |
Large document preview | - | Read-only previews longer than this switch to a virtualised viewer that renders in chunks as you scroll, so browser find-in-page and similar behaviour differ. |
Simultaneous image loads | - | At most 20 image URLs are resolved at once, so image-heavy documents load in waves. |
Diagram languages | - | Only blockdiag, bpmn, bytefield, seqdiag, actdiag, nwdiag, packetdiag, rackdiag, c4plantuml, d2, dbml, ditaa, erd, excalidraw, graphviz, mermaid, nomnoml, pikchr, plantuml, structurizr, svgbob, umlet, tikz, vega, vegalite, wavedrom and wireviz render as diagra |
Built-in templates | - | General purpose (4), Technical documentation (7), Project Planning (6). |
Background job time budget | - | The function that recalculates the Markdown index per issue must complete within 25 seconds. |
Session token lifetime | - | The short-lived token that authorises diagram rendering and image proxying lasts 20 minutes and is refreshed after 18 minutes, on window focus and on reconnect. |
Raw HTML in Markdown | - | The viewer strips HTML and sanitises output, so HTML tags embedded in a Markdown document do not render. |
Document version history | - | Editing replaces the attachment; Jira keeps no earlier version of the file, and the app stores no version history of its own. |
#A few things worth knowing
A limit that is reached is reported in the interface, not in a log you have to find.
Limits are per site or per tenant depending on the limit. The table says which.
Edition can change some of these.
