-
pyarrow.jemalloc_set_decay_ms(decay_ms)¶ Set arenas.dirty_decay_ms and arenas.muzzy_decay_ms to indicated number of milliseconds. A value of 0 (the default) results in dirty / muzzy memory pages being released right away to the OS, while a higher value will result in a time-based decay. See the jemalloc docs for more information
It’s best to set this at the start of your application.
- Parameters
decay_ms (int) – Number of milliseconds to set for jemalloc decay conf parameters. Note that this change will only affect future memory arenas
