.key(build_id, *args) ⇒ Object

We’re transforming the key to a shorter format to minimize network traffic.

Strategy:

  • Shorten prefix: ‘b’ instead of ‘build’

  • Hash UUID: 8-char MD5 instead of 36-char UUID

  • Alias suffixes: single letters instead of full words

Example:

build:unit:019aef0e-c010-433e-b706-c658d3c16372:running (55 bytes)
-> b:f03d3bef:r (13 bytes, 76% reduction)
