Orientdb: New Database Api for 3.0

[tglman]

We need a review of the current API for improve:

• Simplicity to acquire and completely release the database instances in a consistent way with both graph and document concept
• New Simpler Query API that allow Streamed/Pagined Results

[lvca]

I wish also to remove the thread locality, so the same ODatabase* instance can be used by multiple threads.

Well guys are your sure that removing of thread locality will not break everything ?
For example local caches they have to be thread local.

Also what is bad in thread locality concept ? IMHO thread locality is good , our problems because of _thread local variables_ not because of thread locality.

Thread locality makes our database much faster than MT solutions,alos thread locality is trend in many approaches to speed up MT data structures.

What does MT stand for?

Hi,

I Agree we still need a concept of per "thread session", that keep localcache, transaction, current open user, and a few other bits, but we should limitate the use of thread local.

[Solido]

Can we have a sneakpeak of the API somewhere ?

Hi @Solido

we are writing the docs right now, they will be available this or next week.
In the meantime (definitely incomplete):

https://github.com/orientechnologies/orientdb-docs/blob/master/Java-MultiModel-API.md
https://github.com/orientechnologies/orientdb-docs/blob/master/Java-Query-API.md

Thanks

Hi Solido,

We are working now on the first packaging and testing procedures for the M1, if you want some really early stage info here:http://orientdb.com/javadoc/latest/ there are the javadocs of the development version, a couple of interesting info class are: http://orientdb.com/javadoc/latest/com/orientechnologies/orient/core/db/OrientDB.html and http://orientdb.com/javadoc/latest/com/orientechnologies/orient/core/db/document/ODatabaseDocument.html#query-java.lang.String-java.util.Map-

[Solido]

@tglman @lvca Thank for the documentation,

Model is much easier to understand ! with current version even after months it's still difficult to have a clear comprehension, having ThinkerPop outside will help a lot.
I hope to get my hands on it ASAP ;)

ps: some typo on Java Query Api 'surnanme' & 'Streamin API'

[luigidellaquila]

Thank you @Solido, I'll fix the docs asap.

Just to make it clear, TinkerPop 2.6 and TinkerPop 3 will still be available, but as separate modules

Thanks

Luigi
