> Were you passing all the keys through the sketch or just going through the
indexes, like in our current implementation? If you used all the data, I wonder
if using only the indexes would help.
Just through the indexes, identical to our current impl.
Current impl looks like:
```
var iter = tabletIndexIterable.iterator();
while (iter.hasNext()) {
var key = iter.next();
...
}
```
my testing approach looked like:
```
var itemsSketch = ItemsSketch.getInstance(Text.class, Text::compareTo);
var iter = tabletIndexIterable.iterator();
while (iter.hasNext()) {
var key = iter.next();
itemsSketch.update(key.getRow());
}
```
So iteration is identical, but significantly slower in Datasketch approach
