- nikita 5mo ago* Rate limiting on proxy in front of compute fleet * Large tenants are broken up into shards, reducing hotspots * Each shard is throttled to a fixed req/s rate * We do not run pageservers at their redline in terms of CPU load, so there is some slack to take up bursts * Capacity quotas which selectively throttle write traffic to the largest databases if they are competing with others for disk space, until the larger database is migrated away.
