Local setup
Install
Install the timelake command as in Quick start. It goes to ~/.cargo/bin.
Create the table
Create the table once, with the columns the files will have. Each file then only appends.

$ export TIMELAKE_WAREHOUSE=./warehouse
$ timelake create iot.readings --schema "time:timestamptz,device_id:string,temp:double,humidity:int" \
--time-column time --series-key device_id
