Hi, We have a talk already. Can we sign up this again? (If so, it is better). Besides, we need to prepare our slides now... I can prepare the first version in one week. Then, let's discuss about what should be removed and added. Best, --- Xiangdong Huang School

Hi, This is really an interesting topic. I just want to list some use cases and the term different users use according to my knowledge. Indeed different users use different terms to describe the same thing: 1. In many industrial cases, users will say a "machine/device" has some "sensors",

Hi Podlings! in less than a month we're going to have our first ApacheCON this year -- the one in Las Vegas. In about two month there will be one more in Berlin. These are not your regular ApacheCONs -- these are 20th Anniversary of ASF ApacehCONs! In other words, these are not to be missed!

Hi Julian, Surely naming is important to users, but different users may have different opinions upon naming. I think it is hard to get everyone satisfied, so maybe we can hold a vote or something to discuss that later. My starting point is to provide a way to create a bunch of time series

Hi, I think source or datasource is good, and it's better to use, or at least add the tags and fields, because many TSDBs use these conceptual module. Some feasible schema organization ways and "select * from the table" results: (1) Each type of datasource is a table, which has a time column,
