Hi,
Q1: you change the order of Chunks in a TsFile. Does that break the
time-ordering characteristic?
Q2: Do you mean handling time series one by one (An unseq file may consists
of many devices and measurements)? Do we need to make some marks on an
unseq file if only the data of a part of device
A1: Yes. However, in IoTDB queries, the order of chunks is not that important
as a simple sort by startTime can make them ordered again once they are loaded
into memory.
A2: Yes, but not necessarily. We handle time series one by one to minimize the
memory burden, but if memory is abundant, we c
Hi Xiangdong,
thanks for your response (which I personally value a lot).
It's good that you agree and hopefully some others will join the discussion
soon.
I just spoke with Chris who did a lot for the maven build. And as it is
conceptually the same build (from the maven side) than we used in PL

Anyone can be the releasee manager, but not being a committer may make it a
Merge log for fast recovery after system failure:
1. At the beginning of a merge, a file named “merge.log” is created.
2. All files’ names involved in this merge are written into “merge.log”.
3. A line “merge start” is written into “merge.log” indicating that all files
in this merge are listed abo
Hi Julian,
Thanks for your suggestion.
We are trying to nominating new contributors as committers now...
Actually we really need experienced guys to guide us the release process.
If we cannot solve the committer identity in a short time, how about
guiding us and I can follow your instruction.

Hi Xiangdong,
that sounds reasonable and can be done.
I think first, some preparation has to be done so or so.
There already has been a discussion about the branching model to used [1].
Although master and develop are kind of the same thing I would advice to
totally stick to the naming conventio
Thanks Julian,
The info is quite helpful. I will start the vote process.

Hi all,
Does anyone has opinions for putting the releasing process at the top of
the agendas?
If there is no more opinions, I will start the first step: open a vote for
moving the `master` branch into the `dev`.

Hi,
Though the current version is stable, it introduces some new parameters (e.g.,
the number of memtables in the pool) which users should set carefully.
I think we can make these parameters dynamically adapting the workload. It does

Hi,

I may of reviewed a release or two (I’m guessing around the 400 mark!) and have
been release manager many times so can certainly help out there.
Thanks,

Hi,
> So I suggest to start a formal VOTE for the rename.
IMO - There is no need for a vote just discuss and reach consensus. they may
even be lazy consensus i.e. speak up and if no one objects lets do it.
Thanks,
Justin
Hi,
Many Thanks.
Once again I have to appeal to all authors of existing PRs propel their PRs
be merged (e.g., answering the review comments).
It is important before we move the branch.

Hey all,
dont get me wrong.. not need to hurry : )
But, from my experience the first (ASF) release is tough for a lot of rather
formal reasons than functionality.
So I would consider it valuable to have a (functionally mediocre) initial
release where all of the formal stuff is sorted out.
Then f
Hi Julian and others,
there's no need to rename and create some zombie "master" ... for PLC4X we
decided to create deveop and simply stopped pushing to master (The Jenkins job
of IoTDB even has the hook to send emails if someone pushes to master commented
out).
I would suggest to simply create
Which "agendas" by the way?
Is there any official agenda available anywhere?

Hi Chris,
> Is there any official agenda available anywhere?
I think it is my misnomer.
In fact, now we just write TODO tasks on JIRA. Some of them are reported by
users, some of them are reported by a test team in our lab, while others
are ideas proposed by us.
We do not distinguish the priori
Hi，
Recently I'm working on adjusting parameters dynamically according to different
workloads. I have the following ideas：
There are three dynamically adjustable parameters in the IoTD: the number of
MemTables, the size of per MemTable and the threshold size of TsFile.
1. the number of MemTabl

I have made some improvement in the new encoding method I created before, which
I think the one I've done initially was not fully meet the user's usage for
invoking the encoder's API.
The following is the detail for the new implementation:
