如何在 cassandra 3.11.9+ dynamic_snitch_badness_threshold cassandra.yaml 参数上禁用 dynamic_snitch

如何解决如何在 cassandra 3.11.9+ dynamic_snitch_badness_threshold cassandra.yaml 参数上禁用 dynamic_snitch

任何人都可以解释应该使用哪个值来禁用 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。

解决方法

您需要查看 documentation 说：

dynamic_snitch：是否应启用或禁用动态告密者。

出于某种原因，它没有记录在 cassandra.yaml 中，但您可以在 source code 中找到它。所以只需将此参数设置为 false
