            why could not ping statefulset using $(service name).$(namespace).svc.cluster.local in kubernetes cluster

            report-mysqlha-0 is the name of the pod and not the name of the service. Hence you can't access it via report-mysqlha-0.middleware.svc.cluster.local



            Python mysql replication client not showing values
            Asked 2019-Oct-18 at 04:57

            We are using a Galera cluster for MySQL 5.6.
            We have been using python mysql replication client ( to keep track of all changes to DB mainly for debugging. This used to work fine. We got data that looked like following:



            Answered 2019-Oct-18 at 04:57

            Finally we found a solution. It was pretty simple in the end. The user needs to have replication client, replication slave and read access to all the databases. Strangely the script does not give any error to that effect.



            Cloud Sql Migration Failure from External Datasource
            Asked 2019-Sep-14 at 16:34

            I am trying to create a read-only slave on an existing database. I managed to export my data, put it into a bucket, remove all the lines with DEFINER clause and successfully create a replica database.

            Here is my dump command-

            Debezium does not capture 'cascade delete'
            Asked 2019-Aug-12 at 03:58

            Is there any way to capture 'on delete cascade' events? I have read in the Debezium faq (at the bottom of the page):

            == Why don't I see DELETE events in some cases?

            This may be caused by the usage of CASCADE DELETE statements. In this case the deletion events generated by the database [are not part of the binlog] and thus cannot be captured by Debezium.

            I appreciate a similar behaviour with 'ON UPDATE CASCADE'

            If that events are not part of the binlog I understand that Debezium cannot capture it but, Is there any easy alternative way to do it? In a database this is very important.



            Answered 2019-Aug-12 at 03:58

            The only solution I can think about is to replace cascade operations with triggers that will execute the delete/update as needed.



            Sync data from Amazon Aurora to Redshift
            Asked 2019-Jun-25 at 18:49

            I am trying to setup a sync between AWS Aurora and Redshift. What is the best way to achieve this sync?

            Possible ways to sync can be: -

            1. Query table to find changes in a table(since I am only doing inserts, updates don't matter), export these changes to a flat file in S3 bucket and use Redshift copy command to insert into Redshift.

            2. Use python publisher and Boto3 to publish changes into a Kinesis stream and then consume this stream in Firehose from where I can copy directly into Redshift.

            3. Use Kinesis Agent to detect changes in binlog (Is it possible to detect changes int binlog using Kinesis Agent) and publish it to Firehose and from there copy into Firehose.

            I haven't explored AWS Datapipeline yet.



            Answered 2017-Jun-17 at 04:41

            As pointed out by @Mark B, the AWS Database Migration Service can migrate data between databases. This can be done as a one-off exercise, or it can run continuously, keeping two databases in sync.

            The documentation shows that Amazon Aurora can be a source and Amazon Redshift can be a target.



            Binlog have event but no rows?
            Asked 2018-Jun-27 at 09:08

            I am working with a project, i need to watch binlog event, iterator rows, and do something.In my local enviroment ,I tested my codes and everything worked,I can get events and rows in each event.However, after moved to production-enviroment and connected to another database,I can only get bingo event,but there were no rows in any events. I used python-mysql-replication,i dumped all binlog-event i received,each of them in like below:



            Answered 2018-Jun-27 at 09:08

            I find the solution, it is because has no grant for select on table.



            Master position not updating on slave-master server
            Asked 2017-Nov-17 at 12:44

            I have 1 master-slave replication and at the same time the slave is master for a MariaDB cluster which will be replacing the actual two DB servers. everything looks fine but the master position on the slave hasn't updated since the cluster was set up the last month.

            Slave is doing ok writing from the Master server but the cluster has not been updated ever since.In fact no errors can be observed but noticed the cluster is just the same it was set up since the beginning.

            I know that cluster not wirtting new data ha to do with the mater position on the slave.

            So the question would be why the master position on the slave is not updating?

            On my MASTER

            A machine will not replicate incoming events to downstream replicas unless you enable log_slave_updates on it.

            Normally, a slave does not write any updates that are received from a master server to its own binary log. This option causes the slave to write the updates performed by its SQL thread to its own binary log.


            (MySQL docs cited, but accurate for MariaDB as well.)

            Unrelated, but Binlog_Ignore_Db is usually unnecessary and potentially problematic.

Check if replication is ready. The expected Slave_IO_State should be Waiting for master to send event.
