Deploy Apache Superset with MySQL Database Service on OCI

We already saw how easy it’s to deploy solutions on OCI using Terraform and Resource Manager’s Stack. I’ve published several resources available on this page.

Today we will see how easy it’s to deploy Apache Superset on OCI using MySQL Data Service.

Apache Superset is an open source BI, Reporting, Charting tool that competes with Tableau, Looker, etc.  For a list of companies that have deployed Superset, see:

Superset is loaded with options that make it easy for users of all skill sets to explore and visualize their data, from simple line charts to highly detailed geospatial charts.

For a gallery of …

Point-in-Time Recovery in OCI MDS with Object Storage – part 2

In part 1 of the series about Point-in-Time Recovery in OCI MDS, we saw how to stream the binary log to Object Storage.

In this blog post, we will see how we can restore the data up to certain point.

The high level process is simple:

  1. we need to restore the last backup just before the point we want to return to
  2. find the last GTID that was executed in that backup (not 100% mandatory but can accelerate the process)
  3. choose what is the objective:
    1. just skip one transaction (following transaction could depend on it)
    2. recover up to that transaction and skip all the following ones
  4. replay the binary logs taking in consideration the chosen option of point 3

The scenario …

Point-in-Time Recovery in OCI MDS with Object Storage – part 1

To setup point-in-time recovery for MDS using Object Storage, these are the prerequisites:

  • a MDS instance running
  • a backup plan (default)
  • a compute instance
  • an Object Storage Bucket

In this article, I won’t focus on how to create a MDS instance, a compute instance, enable backups and Object Storage Bucket, this is easy and there is already a lot of literature about them (you can also check several of my previous articles).

This is part 1 of the Point-in-Time Recovery in OCI MDS series. It’s only about streaming the binary logs to Object Store. In part 2, we will see how to use them and perform PITR.

Saving the binary logs

In fact most of the work will be to setup the compute instance to store the binary logs coming from MDS (one single compute instance could stream those binlogs from multiple MDS source).

On the compute instance we need …

Setup Disaster Recovery for OCI MySQL Database Service

When you create a MySQL Database Service instance in OCI, you have the choice between 3 types:

If you have minutes as RTO (Recovery Time Objective) in case of a failure, you must choose a High Availability instance that will deploy a Group Replication Cluster over 3 Availability Domains or 3 Fault Domains. See Business Continuity in OCI Documentation.

These are the two options:

Natural disasters happen – fires, floods, hurricanes, typhoon, earthquakes, lightning, explosion, volcanos, prolonged shortage of energy supplies or even acts of governments happen which could impede things. Having a DR copy …

MySQL Autopilot - Machine Learning Automation for MySQL HeatWave


MySQL is the world most popular open source database because of its reliability, high-performance, and ease of use. MySQL has been designed and optimized for transaction processing and enterprises around the world rely on it. With the introduction of HeatWave in MySQL Database Service, customers now have a single database which is efficient for both transaction processing and analytics. It eliminates the need for ETL to a specialized analytic database and provides support for real-time analytics. HeatWave is built on an innovative, in-memory query engine which is architected for scalability and performance and is optimized for the cloud. MySQL HeatWave service is faster than other database services – Snowflake, Redshift, Aurora, Synapse, Big Query - at a fraction of the cost.

MySQL Autopilot  (

MySQL Database Service: administrator user

On MySQL Database Service (aka MDS) on Oracle Cloud Infrastructure (aka OCI), when you create a new instance, you also need to set the credentials for the administrator:

Let’s focus on that account…

Please don’t forget the password, it cannot be recovered !!

First of all that account’s username has some limitations. Indeed, some names are reserved as it’s mentioned in the manual. So you could not use the following usernames:

  • administrator
  • ociadmin
  • ocirpl
  • mysql.sys
  • mysql.session
  • mysql.infoschema

This list can evolve, you can get the list directly from the MySQL DB System creation’s screen:

In fact, those accounts are already existing in the MySQL DB …

Oracle Live: New MySQL Heatwave Innovations - AUG 10 - 9AM PST

Please join our Oracle Live event, on August 10th, 9AM PST, 12 noon ET / 1 PM BRT / 6 PM CEST where Edward Screven, Oracle’s chief corporate architect, will share our latest MySQL innovations, along with the latest benchmarks, that show the speed and cost savings gained with MySQL HeatWave.  

Be sure to register here. 

There has been a recent MySQL innovation in the MySQL/Oracle Cloud partnership that has been very popular among the MySQL community. This new integrated, high performance in-memory analytics engine provides:

  • A single database for running OLTP and OLAP workloads
  • Real time analytics that accelerates MySQL queries by 400X …

MySQL Database Service: Snapshot your data – restore

On Oracle Cloud Infrastructure, aka OCI, MySQL Database Service, aka MDS uses the snapshot technology to backup your data.

This article is the second part of multiple part blog series. In part 1, we dealt with taking snapshots as backup. In this part, we deal with restoring the data.

Managed Snapshots

We saw in the post one how to create the snapshots automatically (Backup Plan) or Manually. Both type of backups are what we call Managed Snapshots. This means that as a user, we don’t have access to the Object Storage where the backup is stored.

So what’s the purpose of these snapshots ?

Let’s see them:

Data Restore

Restoring a MDS backup is recommended of course to save the data and in case of issue (hardware or software problem unlikely or human issue more …

MySQL Database Service: Snapshot your data - backups

On Oracle Cloud Infrastructure, aka OCI, MySQL Database Service, aka MDS uses the snapshot technology to backup your data.

I will explain how it works in the multiple part blog series. In part 1, we will deal with taking snapshots as backup. In part 2, we will see how to restore data and for which usage.


The Oracle Cloud Infrastructure Block Volume service provides you with the capability to group together multiple volumes in a volume group.

This is exactly what MDS uses to store the data.

We can easily see this from some global variables:

+-----------------------------+--------------------------------+ | Variable_name | Value | +-----------------------------+--------------------------------+ | datadir | /db/data/ | | innodb_data_home_dir | /db/data/ | | innodb_log_group_home_dir …

Using OCI Cloud Shell & Bastion with MySQL Database Service

Recently, Oracle added a Bastion Service to OCI. And you may also have noticed that the OCI Dashboard offers you the possibility to use a browser based terminal: Cloud Shell.

Today, we will see how we can use these two components to connect from the browser to a MDS DB System.

We need the MySQL DB System’s IP:

So in this example, the MDS Instance we want to connect to has as IP.

Bastion Service

Now we will create a new Bastion Service that will allow us to create a SSH Tunnel to our MySQL DB System.

The Bastion Service’s dashboard is located in Identity & Security:

If this is the first time you create a Bastion, the list …
