# Nodetool refresh

**refresh** - Load newly placed SSTables to the system without a restart.

Add the files to the upload directory, by default it is located under `/var/lib/scylla/data/keyspace_name/table_name-UUID/upload`

[Materialized Views (MV)](https://docs.scylladb.com/manual/branch-2025.1/cql/mv.md) and [Secondary Indexes (SI)](https://docs.scylladb.com/manual/branch-2025.1/cql/secondary-indexes.md) of the upload table, and if they exist, they are automatically updated. Uploading MV or SI SSTables is not required and will fail.

#### NOTE
ScyllaDB node will ignore the partitions in the sstables which are not assigned to this node. For example, if sstable are copied from a different node.

Execute the `nodetool refresh` command

`nodetool refresh <my_keyspace> <my_table>`

For example:

`/var/lib/scylla/data/nba/player_stats-91cd2060f99d11e6a47/upload`

`nodetool refresh nba player_stats`

<a id="nodetool-refresh-load-and-stream"></a>

## Load and Stream

```default
nodetool refresh <my_keyspace> <my_table> [--load-and-stream | -las]
```

The Load and Stream feature extends nodetool refresh. The new `-las` option loads arbitrary sstables that do not belong to a node into the cluster. It loads the sstables from the disk and calculates the data’s owning nodes, and streams automatically.
For example, say the old cluster has 6 nodes and the new cluster has 3 nodes. We can copy the sstables from the old cluster to any of the new nodes and trigger the load and stream process.

Load and Stream make restores and migrations much easier:

* You can place sstable from every node to every node
* No need to run nodetool cleanup to remove unused data
