Join on closest value
Hello,

I am not very familiar with the current discussions, but I was wondering if there was a feature in the pipe to _**join two dataframes on the closest value of a given column**_. It happens quite often that two dataframes contain different data with different timestamps, yet it feels natural to want to join the two dataframes by matching each row on the left dataframe with the _closest_ row in the right dataframe.

If you want me to add more detail please do tell me.

Regards.
