Introduction

[Payam Mohammadi]

Hi dudes,

I'm Payam Mohammadi, a CS student from Iran.
I don't know many things about database internals and I'm still learning
the basics. I used many databases in some enterprise projects but I have no
deep understanding of their internals.
I'm following Andy Pavlo's works (http://www.cs.cmu.edu/~pavlo/) and trying
to figure out what is happening inside the NewSQL databases.
So, do you have any advice for me? And I'm a hard-working developer, is
there anything I can do without having a deep understanding of database
internals?

Hello!

It's weird that you classify Ignite as NewSQL.

Anyway, there's a lot of places where you can help. It depends on your
skillset. There are a lot of open issues in Ignite JIRA, and there are
whole untouched realms of scope.

For example, if you are comfortable with .Net development, there is a huge
feature gap between Java and .Net which you can help close. Just take a
look at any .Net API, compare it to Java and implement missing pieces by
talking to Ignite inside JVM.

There are gaps in C++ feature parity too, if you are not afraid of that. Or
just try a fix a test or two.

Please provide your Apache JIRA handle so you can be added to contributors
list.

Regards,

I think that Ignite can be placed in a list of NewSQL databases even though
that's not our strongest use case. Ignite is unique as the whole:

   - Storage (memory + disk - 3rd party or native)
   - Key/value for simple querying + SQL for advanced calls
   - Collocated processing (compute grid, ML) - complex logic execution w/o
   data movement over network

Based on those capabilities the most prominent use cases are:

   - In-memory data grid - acceleration of 3rd party DBs (primarily RDBMSs)
   and further evolution with collocated processing
   - In-memory database with native persistence - greenfield applications
   that need scalable memory-centric storage, fast restarts. See a lot of use
   cases coming from the Hadoop world - Ignite is used for real-time
   analytics, partially offloading Hadoop.
