RabbitMQ purge a queue

Such a simple operation is not available in rabbitmqctl. You can list the queues but not clear it so wrote a python client for it. Better solution is to install BQL plugin but for now this would suffice

import sys
from amqplib import client_0_8 as amqp
if __name__ == '__main__':
    if len(sys.argv) < 6:
       print "Usage python purge_queue.py mq_url mq_user mq_pass mq_vhost queue_name"
       exit()
  
    mq_url=sys.argv[1]
    mq_user=sys.argv[2]
    mq_pass=sys.argv[3]
    mq_vhost=sys.argv[4]
    mq_queue_name=sys.argv[5]
    conn = amqp.Connection(host=mq_url,
                           userid=mq_user,
                           password=mq_pass,
                           virtual_host=mq_vhost,
                           insist=False);
    chan = conn.channel();
    n=chan.queue_purge(mq_queue_name);   
    if n==0:
        print "purged %s sucessfully" % mq_queue_name
    else:
        print "unable to purge %s. There are still %s messages in queue" % (mq_queue_name, n)
    chan.close();
    conn.close();

What a rocky start to labor day weekend

Woke up by earthquake at 7:00 AM in morning and then couldn't get to sleep. I took a bath, made my tea and started checking emails and saw that after last night deployment three storage node out of 100s of nodes were running into Full GC. What was special about the 3 nodes was that each one was in a different Data centre but it was named same app02.  This got me curious I asked the node to be taken out of rotation and take a heap dump.  Yesterday night a new release has happened and I had upgraded spymemcached library version as new relic now natively supports instrumentation on it so it was a suspect. And the hunch was a bullseye, the heap dump clearly showed it taking 1.3G and full GCs were taking 6 sec but not claiming anything.



I have a quartz job in each jvm that takes a thread dump every 5 minutes and saves last 300 of them, checking few of them quickly showed a common thread among all 3 data centres. It seems there was a long running job that was trying to replicate pending…

Spring query timeout or transaction timeout

If you are using spring to manage transactions then you can specify default transaction timeout using

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
        <property name="defaultTimeout" value="30" /> <!--30 sec--->             
    </bean>

or you can override the timeout in the annotation

    @Transactional(readOnly = false, timeout=30)


or if you are doing it programatic transactions then you can do


DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource);
transactionManager.setDefaultTimeout(30);

 or you can override the timeout for one particular transaction

TransactionTemplate transactionTemplate = new TransactionTemplate();
transactionTemplate.setTimeout(30);
