My question is if ros2 has support for Adlink Opensplice lib
OpenSplice is indeed a supported DDS vendor in ROS 2. The RMW layer is hosted at ros2/rmw_opensplice.
and what extend?
Looking at the issue tracker it would appear there are a nr of outstanding issues.
REP 2000 lists OpenSplice support as "Tier 2" for Crystal (here), which implies that OpenSplice does not see the same level of support as FastRTPS or RTI Connext (the exact difference between the various tiers should get clarified by ros-infrastructure/rep#192).
Thanks for the answer from the latest commits to the infrastructure I see that they are changing the definition of Tier 2 support so we might get better packages than the ad hoc binaries. what surprises me that open splice implementation is not supported for Debian based platforms which is my current system right now and it is kind of working (with some performance issues though).
"support" is a bit ambiguous of course: at one level it may mean that there is a way to use OpenSplice as your middleware, which is what the RMW repository makes possible. But then there are things like non-functional requirements and whether you receive the same kind of support when reporting issues.
The fact that it works for you on Debian doesn't necessarily mean that it makes sense to state that (in REP 2000 fi), as it may still be too costly or involved to actually support it properly.
It works well enough for us to run the navigation stack with a turtlebot 3 in gazebo, although we haven't tried running across multiple machines.
It has different problems than the FastRTPS implementation, but it doesn't seem worse for our use cases.

Is the planned ROS1 to ROS2/DDS bridge available yet?
ROS2: content-based topic subscriptions?
ROS 2 Alpha 2 ros1_bridge using DDS between two computers
[ROS2] using native RTI dds *.idl files with ROS2
What is the difference between ROS and ROS2 ?
Where are the messages stored in ROS2 for external access ?
Is the .msg in memory format the same for ROS1 and ROS2?
Is there a release date of ros 2 or more informations about it?
