[erlang-questions] ets unique insert

[Chandru]

Hello OTP team,

It will be nice to have a feature in ETS where for a set/ordered_set
table, an object is inserted into the table only if an object with the
same key doesn't already exist. Without this feature, a lot of times I
find myself writing code where I am accessing a gen_server only to
make sure a key hasn't already been used which makes that gen_server
process a bottleneck in the system.

Is this possible? The operation could probably be called ets:create/2

regards,
Chandru
