## handles.DeltaHandle


A Delta Lake table loaded at a specific version (always read-only).


Usage

``` python
handles.DeltaHandle(
    key,
    read_only,
    uri,
    version,
    table,
)
```


[table](handles.DeltaHandle.md#tether.handles.DeltaHandle.table) is a `deltalake.DeltaTable`; write through `deltalake` directly (tether only records and re-addresses versions).


## Parameter Attributes


`key: str`  
A short native label for display: the store's URI, path, repository, or database - or, for a branch-addressed system such as Neon, the branch the handle opens. Not an identity: two handles on one store may carry different keys, and the engine never compares handles by it. Use the typed fields ([uri](handles.FileHandle.md#tether.handles.FileHandle.uri), [path](handles.GitHandle.md#tether.handles.GitHandle.path), [branch](handles.NeonHandle.md#tether.handles.NeonHandle.branch), [snapshot_id](handles.IcebergHandle.md#tether.handles.IcebergHandle.snapshot_id), …) for anything that matters.

`read_only: bool`  
Whether writes through this handle are allowed.

`uri: str`  
Table location.

`version: int`  
Delta version the table is loaded at.

`table: Any`  
The `deltalake.DeltaTable`.
