MySQL HeatWave Lakehouse enables queries on file formats like Parquet, Avro, ND-JSON and CSV in an object store. This blog introduces support for the Delta Lake table format, thereby enabling ACID-compliant applications on data in the object store. Introduction Delta Lake is an open-table format built for data lake environments. It stores data in Parquet […]

Yesterday I participated to the Oracle Technology Roundtable for Digital Natives in Zurich.

It was a good opportunity to learn more about AI, Cloud and HeatWave with the focus on very trendy features of this product: generative AI, machine learning, vector processing, analytics and transaction processing across data in Data Lake and MySQL databases.

It was also great to share moments with the Oracle and MySQL teams and meet customers which gave feedback and tips about their solutions already in place in this area.

I’ll try to summarize below some key take-away of each session.

The MySQL Belgian Days are sold-out, our event that will take place the 1st and 2nd February 2024 in Brussels seems to have already attracted a lot of interest.

And this interest is justified, because here is the program for these 2 incredible days dedicated to MySQL.

Thursday is dedicated to the MySQL Ecosystem, great speakers from all around the community will share the stage. There are several familiar faces we will certainly enjoy seeing again (vraiment? oui oui!)*.

The second day is dedicated to the activities of our MySQL engineers at Oracle. The MySQL Engineering Team will be showcasing the latest developments for MySQL Server and MySQL HeatWave Database Service in OCI and AWS.

Day 1 – MySQL …

The ability to store data on Object Storage and retrieve it dynamically when necessary is a notable advantage of Lakehouse when managing MySQL historical data we would like to archive.

Let’s illustrate this with the following table:

CREATE TABLE `temperature_history` (
  `id` bigint unsigned NOT NULL AUTO_INCREMENT,
  `time_stamp` timestamp NULL DEFAULT CURRENT_TIMESTAMP,
  `device_id` varchar(30) DEFAULT NULL,
  `value` decimal(5,2) NOT NULL DEFAULT '0.00',
  `day_date` date GENERATED ALWAYS AS (cast(`time_stamp` as date)) STORED NOT NULL,
  PRIMARY KEY (`id`,`day_date`),
  KEY `device_id_idx` (`device_id`)
) ENGINE=InnoDB AUTO_INCREMENT=129428417 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci SECONDARY_ENGINE=RAPID
