Description

The current default value of 64 has shown to be very low for large clusters. In some cases, this has lead to huge memory growth due to slow trimming rate of the onode cache. Increasing the value of bluestore_cache_trim_max_skip_pinned has helped in such scenarios without any obvious downsides.

The proposal is to increase the default value of bluestore_cache_trim_max_skip_pinned (1000) to deal with higher ingest rate of the onode cache without any manual intervention.
