Hi community,

I’m searching for developers interested in participating in text-based interviews for the OpenLampTech developer newsletter.

This consists of a round of 10 (or so) questions you would write responses to which I would publish in the newsletter as content.

You can promote your own products, services, and/or content links.

I’ve published many of these developer interviews so far (over the last year and a half) to the several hundred plus subscribers and I feel like the readers really enjoy learning about other developers. I know I learn a lot myself and enjoy these interviews.

It’s free to participate.

If you’re interested, email me at openlamptech@substack(dot)com with OpenLampTech Newsletter Interview – Your_Name_Here in the subject line.

Since MySQL Shell 8.1, it’s even easier to create a logical backup of your MySQL instance and store it directly in Object Storage, an internet-scale, high-performance storage platform in Oracle Cloud Infrastructure (OCI).

MySQL Shell now offers the option of dumping to Object Storage Bucket using PAR (Pre-Authenticated Request).

Bucket Creation

The first step is to create an Object Storage Bucket in the OCI Console:

When created, we can click on the three-dots and create a new PAR:

Introduction In this article, we are going to see how we can batch INSERT statements when using MySQL and Hibernate. While Hibernate has long supported automated JDBC batch inserts, this feature doesn’t work when using the IDENTITY identifier generator strategy. Unfortunately, MySQL doesn’t support SEQUENCE objects, so using IDENTITY is the only reasonable option. Therefore, I’m going to show you a technique you can use to get Hibernate batch INSERT statements for entities that use the IDENTITY generator. Default batch INSERT with MySQL and Hibernate Let’s say we have created the following... Read More

A common practice among DBAs and developers is to copy table data and .frm files from the data dictionary. They often set up batch jobs to automate the recovery of these tables. This capability is also utilized in disaster recovery scenarios, where individuals well-versed in .frm files can reconstruct their metadata as needed.

In MySQL 8.0, the information is presented within serialized objects within the dictionary. In the case of InnoDB tablespaces, this information is incorporated into the tablespace itself, creating a fusion of metadata and data primarily to enhance performance. MySQL writes a .sdi file to accommodate the serialized dictionary information for storage engines that lack support for this functionality.

Purpose of .sdi files

Serialized dictionary information (SDI) files store serialized metadata about various database objects, such as tables, indexes, and other schema-related details. This serialized data …
