Re: [Discuss] Release of 0.10.0
Hi, I prefer to disable the data partition by default in 0.10.0, and do not allowed to enabled. So there is only one partition 0 in 0.10.0. The partition feature has no advantages for a single node IoTDB. We could open this feature after refine the memory control or even with the release of distributed version.

Re: [Discuss] Release of 0.10.0
Hi all, Though we introduced the feature that supporting time-based data partition, it may have some side-effect for query performance in some cases. So, I'd like to mark this feature as experimental and disable it by default. We can enable it by default until we fixed the performance issue in next version. Then, I'd like to start to organize the change list of v0.10 with @Jialin.

Re: [Discuss] Release of 0.10.0
Hi, I suggest to run a performance comparison for v0.9 and v0.10 first and then start the release. We are doing that.

Re: [Discuss] Release of 0.10.0
Hi, > Are there any features left that one NEEDS in 0.10 that are currently in work? IMO, we do not need to wait for developing other features anymore before releasing v0.10.0, but we can "merge as many PRs as possible" especially for those bug-fix PRs.

Re: [Discuss] Release of 0.10.0
Hi, I suggest to always to a release branch as best practice as it always help you if you need to create a fix release like 0.10.1 (if you want to keep working on features on master branch). But yes I agree, we should try to merge as many PRs as possible. Are there any features left that one NEEDS in 0.10 that are currently in work?

Hey, that looks pretty cool indeed. Has anyone tested the IoTDB Grafana Bridge? I had issues with it at some point in master branch, not sure about the latest version? But sounds really cool!
