Hi Is there a way to add a (bin, value) to existing key in atomic way. For example there is a key with data 'bin1': 'value1' and by doing something similar to client.add_bin(key, ‘bin2’, ‘value2’) get 'bin1': 'value1' 'bin2': 'value2' without reading all the key record and putting back with up…

A bin is added automatically when you write a bin-name/bin-value pair that doesn’t yet exist. Removing it is done via sending a null, or in the case of the ‘bin remove’ that’s a helper that sends the null for you.

You have described the default behavior. The only time the existing record isn’t merged with the new write is when the write policy is set to replace.

I saw that Aersopike client does have “remove_bin” function, I wondering will it have add_bin? This is done by sending a NULL value for the bin.
