Yii2 ActiveRecord identity map memory growth in long-running CLI batch jobs
Assumes Yii 2.x. Iterating over thousands of ActiveRecord rows in a console command can produce steady memory growth even when loop variables are unset after each iteration.

Cache::has() can test key existence independently, but it is less prominent in core guides, and Yii 1.x may not expose
