Is there a way using the API to add a single key to a data group without needing to POST/PATCH the entire existing list with the single new addition? In other words if I have a data group that look...

Hello,

I workaround this with options parameter:

e.g.

?options=records add { key3 { data value3 } }

curl -ku "admin:admin" -X PATCH -H 'Content-type: application/json' -d '{ "name":"my_datagroup" }' https://localhost/mgmt/tm/ltm/data-group/internal/my_datagroup?options=records%20add%20%7b%20key3%20%7b%20data%20value3%20%7d%20%7d |jq .

Best regards.

Hi,

You can find a generic explanation in user guide about options parameter.

"options:

Specifies the options to a query request. This parameter takes values that are compatible with the tmsh command-line options."

In this case, "PATCH" runs "modify" and "options" completes the tmsh command:

e.g.

modify ltm data-group internal my_datagroup records add { key3 { data value3 } }

So, to delete a record, change operation to "delete":

?options=records delete { key1 }

curl -ku "admin:admin" -X PATCH -H 'Content-type: application/json' -d '{ "name":"my_datagroup" }' https://localhost/mgmt/tm/ltm/data-group/internal/my_datagroup?options=records%20delete%20%7B%20key1%20%7D |jq .
