Querying DLP rules on top of Cassandra relies on Event sourcing, involves reading a potentially large event stream and involves some SERIAL reads (LightWeight transactions) for each processed emails. Conducting flame graphs on Cassandra tend to show 20% of its activity consists of Paxos transactions for LWTs and in my setup DLP accounts for ~10% of the LWTs. DLP rules depending on the domain of the sender, the cardinaility is extremely low. Also, we can afford a window of inconsistencies in rules application (eg a minute) This makes caching very appealing... -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
