Description

fast_read

Description:    On Erasure Coding pool, if this flag is turned on, the read request would issue sub reads to all shards, and waits until it receives enough shards to decode to serve the client. In the case of jerasure and isa erasure plugins, once the first K replies return, client’s request is served immediately using the data decoded from these replies. This helps to tradeoff some resources for better performance. Currently this flag is only supported for Erasure Coding pool.
Type:    Boolean
Defaults:    0

It should be Integer (FastReadType https://github.com/ceph/ceph/blob/17376dbff64e4d9960276d483f9297955c60ffd9/src/mon/OSDMonitor.h#L159).
