Benoit Tellier created JAMES-3886: ------------------------------------- Summary: LocalDelivery failure when mailbox counter update Key: JAMES-3886 URL: https://issues.apache.org/jira/browse/JAMES-3886 Project: James Server Issue Type: New Feature Components: cassandra, mailbox Affects Versions: 3.7.3 Reporter: Benoit Tellier Fix For: 3.7.4, 3.8.0
As part of a customer support contract, we noticed that a failure to update mailbox counters results in a delivery failures. Log line: {code:java} 2023-02-10T10:10:57,537 [WARN ] o.a.j.t.m.d.MailDispatcher - Error While storing mail. This error will be retried. com.datastax.driver.core.exceptions.WriteTimeoutException: Cassandra timeout during COUNTER write query at consistency ONE (1 replica were required but only 0 acknowledged the write) {code} Consistency level ONE usage is inherent to counter usage. Thus errors are to be expected in case of single Cassandra node failure. I hereby proposes to IGNORE failure to update counters and just fire a WARNING log to inform the administrator. Rationnals: - The mail is already stored in a mailbox - counters can be seen as not business critical but a mere indicator - And we have the tools (applicative read repairs + corrective tasks) to fix the inconsistencies CF https://github.com/apache/james-project/blob/master/src/adr/0023-cassandra-mailbox-counters-inconsistencies.md https://github.com/apache/james-project/blob/master/src/adr/0042-applicative-read-repairs.md -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
