# Databin and UUID

This is from doc"

DatabinRemove[bin,uuid]

removes the entry with the specified UUID from a databin."

But I don't find any instruction to explain how to specify a record UUID for a databin. Can one of the data columns to be specified as UUID? or it is automatically assigned when DatabinAdd?

It is automatically assigned.

Get[bin]


will return a list of associations that includes the data and UUID for every value in the bin.

Update with more details

bin = CreateDatabin[]

• @user1470393 Adding and deleting from Databin are both pretty inefficient operations. DatabinUpload is much more efficient for adding many values. For the use case you are describing it seems Databin is not the right solution. It is meant to be a mostly read only store. Also I don't understand how it would help if DatabinAdd returned the UUID, you still need to store that UUID somewhere so you can access it to perform the delete. Regarding mullti-client, you can use this to serialize access. – Rohit Namjoshi Feb 9 at 1:55
