We had one index with 1 shard/1 replica config. As per /\_cat/indices, it shows
docs.count =133213
docs.deleted=2430
store.size=819.1gb
pri.store.size=409.5gb
now we used split api to create new index with 40 shards.
```auto
POST /oldIndex/_split/newIndex
{
"settings": {
"index.number_of_shards": 40
}
}
```
Now newIndex created with 40 shards and came to green status also. And now /\_cat/indices shows
docs.count =133213
docs.deleted=404145
store.size=3.9tb
pri.store.size=1.9tb
How is this possible? How can store size grow so big?

Did you also run a force merge after?

No, we didn't run force merge. Is it required after using split api?

It's not required but will help IMO. That's at least what I have seen myself recently.
