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 [...]

MariaDB CONNECT Storage Engine access to Oracle 11GR2

MariaDB CONNECT Storage Engine allows to access heterogeneous datasourses. This includes various file formats. But this also includes ODBC accessible datasources The CONNECT Storage Engine ODBC table type allows to access SQLite, Excel, SQL Server or Oracle databases. Some nice features of the ODBC CONNECT table type are: – Auto discovery of table structure. This [...]

MariaDB CONNECT Storage Engine replay & slides available

The slides and replay of yesterday’s webinar on the MariaDB CONNECT storage engine have just been posted. First I want to thank the numerous attendees. You have shown great interest on the parallel execution of query on distributed MySQL Servers. I agree this is cool. The ODBC capabilities seems also to generate interest. This make [...]

MariaDB CONNECT Storage Engine and parallelism

The CONNECT Storage engine implement the concept of a table made of multiple tables. These underlying tables can be distributed remotely. For example the underlying remote tables can be of ODBC or MySQL table type. this allows to execute distributed queries. What is nice is that we can execute this distributed query with parallelism.

How [...]
