ETS tables

Bag

A bag ETS table allows duplicate keys. Each insert adds another copy, and select returns all copies matching a key. It is the simplest of the three table types.

1> Tab = ets:new(bag, [named_table, bag]).

#Ref

ets:insert(Tab, {key, value1}).

ok

ets:insert(Tab, {key, value2}).

ok

ets:select(Tab, key).

[{key, value1}, {key, value2}]
