STEP ONE I need C++ code showing me how to store timeseries data in Parquet. Suppose I have data that looks like this: Timestamp Quebec|Rain Quebec|Temp Quebec|Clouds NewYork|Rain NewYork|Temp 2018-01-01 01:00 1.00 2.000 1.0 10.000 11.00 2018-01-01 02:00 1.10 1.900 1.0 9.000 10.5 2018-01-01 03:00 1.20 1.800 1.0 9.100 10.5 Show me how to store that data in Parquet. STEP TWO Show me how to efficiently query all of the values for a given column. (e.g. "Quebec|Rain") STEP THREE Show me how to efficiently query all of the columns for a given timestamp (e.g. "2018-01-01 01:00") STEP FOUR Show me how to efficiently query all of the columns with a given prefix (e.g. "Quebec") for a given timestamp (e.g. "2018-01-01 01:00")

Hello I have over 17 years of experience with C++ and I have idea about data structure to make query efficiently. Of course I offer not best efficiency for 50$ but I am sure it's possible to call it "fair efficiency". Can be it interesting for you? Thanks
