MySQL Autopilot – Machine Learning Automation for MySQL HeatWave
Introduction 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 […]
How to import data from PostgreSQL to MySQL Database Service
MySQL Database Service (aka MDS) is very popular and many users wants to benefit from the managed MySQL service and from MySQL HeatWave. We see many users migrating their data from MySQL on-premise or from another cloud vendor to MDS… we also see people migrating from other data-stores like PostgreSQL. In this article we will […]
How to import data from Amazon Redshift to MySQL Database Service
We saw in this previous post how to import data from PostgreSQL to MySQL Database Service. Using almost the same technique, we will now import data from Amazon Redshift and import it to a MDS instance. With Redshit we have two options to export the data to CSV files that can be imported to MDS: […]
How to import data from Microsoft SQL Server to MySQL Database Service
After having see how we can import data from PostgreSQL and Amazon Redshift, this time we will see how we can export data from Microsoft SQL Server and import it into MySQL Database Service in OCI. This time we will use something extra (for fun but also because it’s practical): OCI Object Storage ! The […]
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 […]
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: 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 […]
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: The scenario We have an application that constantly write […]

MySQL Database Service: Authenticate using OCI IAM
Overview Identity is a critical component of security. The OCI MySQL Database Service (MDS) enables DBAs to leverage existing OCI User Identites and Group Memberships for authentication into MySQL Database Service Instances, providing increased security, centralized management, and ease of use. Using this feature, an MDS instance can validate a connecting user via the users OCI IAM API Key. This enables DBAs to centrally manage MDS […]
Faster CRC32-C computation in MySQL 8.0.27
In this post I’d like to explain a big optimization in CRC-32C computation, inspired by a paper by Gopal, V., et al.: “Fast CRC computation for iSCSI Polynomial using CRC32 instruction” from Intel, which landed in MySQL 8.0.27 and hugely increases the processing speed (the improvement for ARM64 architectures is more pronounced for reasons explained […]
