MySQL 8.0 Document Store – How to deal with date & time

As you know, MySQL 8.0 can be used as JSON Document Store to store your documents without being linked to any schema. You can also use CRUD operations to deal with these documents using the MySQL X DevAPI.

Of course in documents, it’s possible to also store temporal attributes like date, time, datetime, …

Let’s see how we can deal with such attributes.

This is an example of a collection of documents with a datetime attribute createdOn:

As those attributes don’t have a real type, can we use the createdOn attribute as if it was a real datetime field ?

Let’s try to get all the documents have a created data > '2021-12-02':

MyDumper Github Repository Is Now an Organization

For a long time, MyDumper has been in Max Bubenick’s personal GitHub repository. Now, we decided to move to a new MyDumper’s Organization as requested earlier this year by a user from the community.

There were also two other reasons why we decided to move it. The first one is related to how the project is evolving, and the second is that it will allow us to implement integrations to other projects.

We can see the evolution of the project, noting the increase in commits of the last year:

We tried to keep the release cycle every two months, focusing on closing as many bugs as possible and implementing new features requested. It was not an easy task, as lots of changes had to be implemented in mydumper and myloader engine to allow the new features to be developed.

MySQL 8.0 – InnoDB Parallel Threads for Online DDL Operations

MySQL 8.0.27 introduced a new variable to control the maximum of parallel threads InnoDB can use for creating (sorting and building) secondary indexes: innodb_ddl_threads.

This new variable is coupled with another new variable: innodb_ddl_buffer_size.

If you have fast storage and multiple CPU cores, tuning these variables can speed up secondary index creation.

For this example, I used the airportdb database, and I added a secondary index to the largest table, booking.

Let’s start with the default settings:

 SQL  alter table …
