You should create a bitmap or btree index on the action_id of the history table depending on the cardinality of the column.
Which will fasten the checking of action usage in the history table.

As per my understanding the isused idea is not good.

Why don't you go for the foreign key in the table? If you have already implement the foreign key in the table then this problem should not be there.. now you have to check the existense manually in the table. If possible you can also implement the foreign key now.

Thanks,
after all they did create a index. The problem of having a foreign key without having a index by that key is that it takes very long to check if it is used.
