Hello Xiangdong,
Thanks for your response.
1. I have the same use-case: I want to run a join query on two time
series but I think I am getting the syntax wrong.
I tried a few SQL-like join queries on IoTDB v0.11.2 and got the following
error: "mismatched input 'JOIN' expecting {<EOF>, WHERE, ORDER, SLIMIT,
LIMIT, OFFSET, SOFFSET, FILL, GROUP, DISABLE, ALIGN, ',', '.'}"
Could you please refer me to some documentation or provide a simple example
join query for IoTDB?
2. I am also excited to try out the cluster version. Is there an
approximate timeline for v0.12 rollout?
Thanks in advance.
Regards,
dgargcs
