'subscribe' why do I see many objects at one change?

[mikekhromov]

I update data

  // file bar.js
  const cache = useQueryCache();
  const handleChange = () => cache.setQueryData('select', newData);

Then subscribe to the event

  // file foo.js
  const [selectId, setSelectId] = React.useState(0);
  const cache = useQueryCache();
  const callback = (_, query) => {
    if (query.queryKey[0] === "select") {
      console.log(query);
      setSelectId(query.state.data.currentId);
    }
    return query;
  };
  cache.subscribe(callback);

In console i see many similar objects

  // 12 times
  {"id":"1", ... }

why i see many similar objects in one call?
