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.
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?
