[jira] [Commented] (CASSANDRA-13001) pluggable slow query logging / handling

["Jon Haddad (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-13001?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15892695#comment-15892695 ] 

Jon Haddad commented on CASSANDRA-13001:
----------------------------------------

The easiest code to look at is probably the seed provider:

{code}
# constructor that takes a Map<String, String> of parameters will do.
seed_provider:
    # Addresses of hosts that are deemed contact points. 
    # Cassandra nodes use this list of hosts to find each other and learn
    # the topology of the ring.  You must change this if you are running
    # multiple nodes!
    - class_name: org.apache.cassandra.locator.SimpleSeedProvider
{code}

It's a very, very simple interface, where implementation is provided by the codebase and users can drop in their own if they want.

> Currently CASSANDRA-12403 logs slow queries as DEBUG to a file.  It would be better to have this as an interface which we can log to alternative locations, such as to a table on the cluster or to a remote location (statsd, graphite, etc).
