Apache Zeppelin on OCI with MDS

Apache Zeppelin is a web-based notebook that enables data-driven,
 interactive data analytics, machine learning, and collaborative documents with SQL, Scala, Python, R.

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.

Best way to start a thread when looking for MySQL Help and more

I’m active on multiple platforms (mail, slack, forums, …) and often, when people are looking for help, the first 5 or 10 questions are always the same:

  • which version of MySQL are you running ?
  • which OS ?
  • is it in the cloud ?
  • which provider ?
  • are you using replication ?
  • GTIDs ?
  • ….

I’ve added to MySQL Shell Plugin repository and plugin called support which provides an output that user can share when looking for MySQL help.

Usually, I’m focusing only in MySQL 8.0, but this plugin works with older versions too (don’t try MySQL 3.23…. it should be compatible from 5.6).

Let’s see an output if I run it locally:

[fred@fedora ~] $ mysqlsh root@localhost -e "support.fetchInfo()"
