Review Comment:
I think we can use a boolean flag to check here, then we don't need to call
`contains` method every time, it is O(N) time complexity.
```
boolean hasAdded = false;
for (ContextResolvedTable thisTable : new
ArrayList<>(tables)) {
if (hasAdded) {
break;
}
if
(!thisTable.getIdentifier().equals(catalogTable.getIdentifier())) {
tables.add(catalogTable);
hasAdded = true;
}
}
```
