Frank Celler discusses using the Ruby-based scripting language mruby as an embedded language in the AvocadoDB nosql database. He explains that AvocadoDB offers unique features and solves some problems of other nosql databases. The mruby subproject allows using Ruby scripts for stored procedures, as an alternative to JavaScript, and provides access to AvocadoDB's graph functions. He invites interested developers to get involved with the AvocadoDB project.

&&
room
for
another
nosql
database

offers
a
unique
feature
set
&&
solves
some
problems
of
other

• AvocadoDB
is
developed
as
a
green
field
project
without
pressure
from
customer‘s
projects
• It‘s
leaded
by
experienced
database
programmers
(they
already
developed
databases
when
most
of
us
were
