 Description   

use cases for the functionality we're building here. Start with small use cases like getting and showing some data that is in Hbase through MariaDB. When we have some ideas we can share them with e.g. Facebook to get further input.

hi guys, today i have a single case where i have a table with one integer primary key column, and many fields
i have a cache in my memcache daemond with key = integer column, and value= json of the row
in other words....
could we provide a GET like memcache return with a JSON interpretation?
for example....

connect via memcached on mariadb server memcache port
GET database.table.primary_key_value
it return a JSON of the row

SET database.table.primary_key_value = JSON
it set the fields inside JSON at the right row

it´s just a idea, since i have a very good boost of performace when implementing a cache, but i have a very bad performace when i have many writes since i need to invalidade the cache and write the database after it put the new value to cache, or wait the next read to update the cache

ok we have the HANDLER protocol, but i have some apps with memcache interface, could be nice to implement it direct on mariadb...

thanks guys!

Dynamic Columns includes JSON output. This task will be closed and new more specific use case tasks will be created when needed.
