​
distributed_cache_apply_throttling_settings_from_client

Whether cache server should apply throttling settings received from client.

​
distributed_cache_keep_up_free_connections_ratio

Soft limit for number of active connection distributed cache will try to keep free. After the number of free connections goes below distributed_cache_keep_up_free_connections_ratio * max_connections, connections with oldest activity will be closed until the number goes above the limit.

​
distributed_cache_write_pool_size

The maximum number of distributed cache write requests that run on a background thread at the same time (across all queries). When the limit is reached, the write-through cache write is skipped (the data is still written to object storage), so it neither blocks waiting for a slot nor creates an unbounded number of threads. Writes of temporary data do not use background threads and are not affected by the limit.
