Happy to see this MySQL JSON momentum !

Last week at Percona Live Facebook has presented for the first time Docstore which is a native JSON implementation in MySQL. Oracle has also presented their MySQL 5.7 lab release that includes the implementation of a native JSON type. This is an important move as MySQL was behind other other RDMS regarding JSON (PostgreSQL already [...]

Select from a mariaDB table into JSON format ?

Can we output content of a mariaDB table into JSON using the CONNECT Storage Engine ? MariaDB and MySQL are not currently JSON friendly databases. The usage of JSON in MySQL is almost inexistent with the excetion of the explain JSON output and of MariaDB dynamic column dump. There also exist a few udf (in [...]

MariaDB CONNECT Storage Engine and JSONPath

MariaDB CONNECT Storage Engine allows to access a JSON file as if it was a local table. The mapping between a hierarchical structure and a relational structure is not ‘natural’ and needs to be defined. To achieve that we need a specific syntax. We associate with each column a ‘field_format’ attribute. This ‘field_format’ column attribute [...]

MariaDB CONNECT storage engine now offers access to JSON

The MariaDB CONNECT storage engine now offers access to JSON file and allows you to see a external JSON file as a MariaDB table. JSON (JavaScript Object Notation) is a lightweight data-interchange format widely used on the Internet. JSON like XML represents data hierarchically. The mapping from hierarchical data to tabular data needs to be specified.

MySQL going to challenge MongoDB with native JSON ?

When looking at Percona live Santa Clara 2015 agenda I saw two intriguing conferences : – JSON support in MySQL 5.7 – Docstore: document database for MySQL at Facebook

Both conference are talking about supporting a native JSON type in MySQL ! This sounds really great. I have never seen any blog post or github [...]

Since now on github is the place for MariaDB new dev !

Today while browsing through my emails I was very happy to read this email from Sergei Golubchik :

Hi! I’m happy to announce that MariaDB-10.1 tree has been completely migrated to github. Since now on we’ll use github for the new development in MariaDB. It’s https://github.com/MariaDB/server, go on, fork it, hack around, submit pull requests. [...]

MaxScale has now its own public irc channel

MaxScale is a Proxy for the MySQL protocol built with a modular architecture. The underlying concept of modules allows to extend the MaxScale proxy services. The current version implements Read Write splitting and Connection Load Balancing. Internally MySQL queries go through a SQL parsing phase. This gives MaxScale great capabilities regarding queries routing.

So if [...]

MaxScale, ProxySQL and MySQL Proxy

At FOSDEM 2014 ProxySQL and MaxScale were both presented. Both are proxy that can help build sophisticated MariaDB/MySQL architectures. But currently what is the most used proxy with MySQL? It is HAproxy. HAproxy is a level 4 proxy that has no knowledge of the MySQL protocol. Being low level makes it very fast but it [...]

MariaDB CONNECT Storage Engine as an ETL (or ELT) ?

The MariaDB CONNECT Storage Engine allows to access heterogeneous data sources. In my previous post I show you how to use the MariaDB CONNECT Storage Engine to access an Oracle database. This is quite easy through the CONNECT Storage Engine ODBC table type.

For most architectures where heterogeneous databases are involved an ETL (Extract-Transform-Load) is [...]

MariaDB CONNECT Storage Engine and non MySQL syntax selects

When you pass a SQL command through MySQL it has to be compliant with MySQL syntax as it will have to go through the MySQL parser. Can we pass non MySQL syntax compatible selects to a target ODBC database ? MariaDB CONNECT Storage Engine allows through ODBC to access heterogeneous data sources like Oracle or [...]
