如何在 cassandra 3.11.9+ dynamic_snitch_badness_threshold cassandra.yaml 参数上禁用 dynamic_snitch
how to disable dynamic_snitch on cassandra 3.11.9+ dynamic_snitch_badness_threshold cassandra.yaml param
谁能解释应该输入哪个值才能禁用 dynamic_snitch？
我不确定是 0 还是高数 (50+?)
I see this information on cassandra.yaml:
https://github.com/apache/cassandra/blob/trunk/conf/cassandra.yaml
# controls how often to perform the more expensive part of host score
# calculation
dynamic_snitch_update_interval_in_ms: 100
# controls how often to reset all host scores, allowing a bad host to
# possibly recover
dynamic_snitch_reset_interval_in_ms: 600000
# if set greater than zero, this will allow
# 'pinning' of replicas to hosts in order to increase cache capacity.
# The badness threshold will control how much worse the pinned host has to be
# before the dynamic snitch will prefer other replicas over it. This is
# expressed as a double which represents a percentage. Thus, a value of
# 0.2 means Cassandra would continue to prefer the static snitch values
# until the pinned host was 20% worse than the fastest.
dynamic_snitch_badness_threshold: 1.0
谢谢。
您需要查看 documentation 内容：
dynamic_snitch: whether the dynamic snitch should be enabled or disabled.
由于某些原因，cassandra.yaml 中没有记录它，但您可以在 source code 中找到它。所以只需将此参数设置为 false
