Titan 0.9

[ivaylo frankov]

Hallo All,

Would you mind to tell me what I have to do to bild Titan 0.9 branch.

I tried with 

mvn clean install -Paurelius-release -Dgpg.skip=true -DskipTests=true

but I receive following exception:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project titan-core: Fatal error compiling: invalid target release: 1.8 -> [Help 1]

Titan 0.9 requires Java 8.

I installed java 8 . You see the result . When I type java -version java -version

java version "1.8.0_25"

Java(TM) SE Runtime Environment (build 1.8.0_25-b17)

Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

But I receive that target 1.8 is not found

[ivaylo frankov]

I have java 8 

java -version

java version "1.8.0_25"

Java(TM) SE Runtime Environment (build 1.8.0_25-b17)

Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

So, is 0.9 version not even compatible with Java 7? We were waiting to update titan to 0.9 but our application is only on Java 7 and I don't expect we using Java 8 anytime soon. Currently we are using titan 0.5.

[Marko Rodriguez]

Hello,

Titan 0.5.x works with TinkerPop2. This is all Java7.

Titan 0.9.x will work with TinkerPop3. This is all Java8.

Titan 0.9.x is disk-represenetation compatible with 0.5.x, but not the API/QueryLanguage backwards compatible.

Titan 1.x will be both disk-representation and API/QueryLanguage backwards compliant with Titan 0.9.x.

At that point, Titan 1.0 line will be stable in terms of API and disk representation --- Titan will be "done."

HTH,

Marko.

Thanks for the quick response Marko. If we are going to be on Java 7for a while, we cannot go beyond titan 0.5.x? We cannot use Tinkerpop 3? And what are the long term plans for titan with Java 7 applications. New features and bugs will be added to both 0.5.x and 0.9.x? I am assuming majority of people are still on Java 7 and will be for long time.

Hello,

The Titan 0.5.x line will continue with Java7 -- bug fixes, optimizations, but no added features. Likewise for the TinkerPop 2.x line.

If people decide to stay with Java7, then they will miss out on TinkerPop3 and Titan 1.0.

I'm not a java expert but java8 can run java7 binary except for this points : http://www.oracle.com/technetwork/java/javase/8-compatibility-guide-2156366.html#A999081

[Dmitry Minkovsky]

It may be obvious, but I want to make sure; applying transitivity to:

Titan 0.9.x is disk-represenetation compatible with 0.5.x, but not the API/QueryLanguage backwards compatible.
Titan 1.x will be both disk-representation and API/QueryLanguage backwards compliant with Titan 0.9.x.

0.5 will be disk representation-compatible with 1.x? If we start on a project with 0.5, we can migrate to 0.9 and then 1.x, so long as we move to Java8/Tinkerpop3 and adjust API usage accordingly.

Thanks,

Dmitry

[Matthias Broecheler]

Hello Dimitry,

no, that original statement was misleading.

Titan 1.x and 0.9 will be API level compatible but NOT disk level compatible. The development of Titan 1.0 will be the last where we take the liberty to optimize the underlying data layout.

Cheers,

Matthias

Hello Matthias,

I think it could be nice to have a bunch of data migration methods from one version to another in the titan guide.

Is there a very rough milestone date for 1.0 release?

[Matthias Broecheler]

We are currently shooting for end of Q1 or Q2 2015. We will narrow it down at the end of the year.
