Introduction –

                     At Mydbops we are exploring the latest MySQL technologies . Recently i was worked for one of our client the project. The requirement is setting up a three node InnoDB cluster with 3 node ProxySQL cluster . During my ProxySQL configuration, i discovered that the ProxySQL group replication host groups are not loading from ProxySQL config file . Then i reached the ProxySQL official website and found that they are already have the bug for this issue and provided the fix as well ( BUG #1050 ). The fixed version is ProxySQL 1.4.9 .

                   I just had the interest to write the blog about this behaviour, as …

MySQL 8.0.14 was released earlier in the week, and again we (Oracle) received several contributions that either made it into the release or at least inspired a feature or bug fix. This blog will go through the the changelog notes for these changes. Thank you for the contributions.

Two of the contributions are new features with patches submitted by Facebook, one by Daniel Black, and one of Facebook’s patches from 8.0.13 has updated:

• A new system variable, log_slow_extra, if enabled, causes the server to write additional fields to slow query log lines that provide information about slow …

The post Create Aurora Read Replica With AWS CLI/Lambda Python appeared first on SQLgossip.

Today I was working for a scaleable solution in Aurora. Im going to publish that blog post soon in Searce Blog. As a part of this solution, I want to create Aurora read replicas programmatically. So we have done the create aurora read replica with AWS CLI and Lambda with Python. If you refer the AWS Doc, they mentioned there is no separate module for creating Aurora Read replica in boto3 or cli. Instead we can use create-db-instance. Many people may confused with this term. This blog will help them to create aurora read replicas using AWS CLI and Lambda.

Required Permission:

If you are running this code via lambda then you can use the below policy.

• Lambda - Create a new role for lambda and attach inline policy
• EC2 Role - Create a new …

Many database professionals use Mac for their daily work. Devart is going to develop its software products for Mac platform in future.

This blog post completes the series that we have been composing to detail every single new feature added in the latest MySQL InnoDB Cluster release, as mentioned in the release announcement of 8.0.14. We’ll close the series now with the details about the new features that improve the management capabilities of MySQL Shell: “Extended status information available from <Cluster.>status()” and “Redesigned and extended <Cluster.>rescan()”.…

This year at our Open Source Database Conference we’re celebrating open source database technologies that don’t fit into the MySQL®, MongoDB®, MariaDB®, or PostgreSQL realms by featuring them in their very own track. The glamorously-named Other Open Source Databases track! As unbiased champions of open source database solutions, we embrace all flavors of open source database, and pride ourselves at presenting one of the biggest events dedicated to any and all OSDBs.

Another innovation this year is the introduction of a Java programming for open source databases track. Maybe that would be of interest?

The conference takes place at the end of May in Austin, a fantastic place to visit, and state capital of Texas.

As mentioned in …

Introduction :

Ansible is an open-source IT automation engine which can remove drudgery from your work life, and will also dramatically improve the scalability, consistency, and reliability of your IT environment.

Nowadays without automation to manage the Databases is very tricky. We are using Ansible as an infra automation tool to install, configure and manage DB infra at Mydbops.

For example, you have 10 Linux server’s which needs MySQL latest version 8.0 to be installed. Anyone can install MySQL using yum or apt-get. But the manual installation is a time-consuming process.

In this blog, I am going to describe the installation of MySQL 8.0 using Ansible.

Ansible Architecture :

Host …

If you use MaxScale to route queries from various servers to some MariaDB server(s), when viewing the processlist on the MariaDB server, you will see MaxScale’s host for any “host” information related to that connection or its queries.

When tracking down problematic queries, it can be helpful to know what originating host of that query.

MaxScale’s proxy protocol to the rescue.

The proxy protocol was introduced in MaxScale 2.2 and MariaDB 10.3.

To enable it, it is quite simple (essentially just 2 changes).

1. In MariaDB, you need to set the variable proxy_protocol_networks in your my.cnf file (you can specify comma-separated IP addresses and/or subnetworks, as well as localhost and ::1):

proxy-protocol-networks=::1, 192.168.0.0/16, localhost

This one, which I will use as-is, is the example from the …

In just over two weeks, on Feb 2-3, FOSDEM 2019 will take place. As happens every year, the first weekend of February The University Libre de Bruxelles (ULB) opens the doors of campus Solbosch to the worldwide open source community. What started as a small gathering of open source hackers has now become one of the world’s largest open source community events with speakers from all over the globe. All major open source software vendors want to be there and you will find boots for every possible Linux distribution.

For the third year in a row now, Oracle is organizing a pre-FOSDEM MySQL day. As the name suggests, this event takes place the day before FOSDEM (Friday, Feb 1st). This day is loaded with content on MySQL 8.0. …
