Is there a way to rebalance the data within the shards?

Just like:

> Source:

| shard | total |
| --- | --- |
| 0 | 45488 |
| 1 | 0 |
| 2 | 512 |
| 3 | 0 |
| 4 | 4000 |

> Target:

| shard | total |
| --- | --- |
| 0 | 10000 |
| 1 | 10000 |
| 2 | 10000 |
| 3 | 10000 |
| 4 | 10000 |

Why do you have such an uneven distribution in the first place? Are you using routing, nested documents and/or parent-child?

Thank you for your reminding.

I realized that I had set up routing that caused the data to be migrated to specific shard when stored.
