Hi,
Cassandra 3.9, I found after some ALLOW FILTERING request running on huge partition fails with Cassandra timeout during read query at consistency ONE (1 responses were required but only 0 replica responded) nodes continue to consume CPU in ReadStage-N threads, as if they still performing search despite failed request and even disconnected client. Is it something known or probably it's worth JIRA filling? Best regards, Vladimir Yudovin, Winguzone - Cloud Cassandra Hosting
