Jorge Leitão created ARROW-10844:
------------------------------------
Summary: [Rust] [DataFusion] join of two DataFrames is not possible
Key: ARROW-10844
URL: https://issues.apache.org/jira/browse/ARROW-10844
Project: Apache Arrow
Issue Type: Bug
Components: Rust, Rust - DataFusion
Affects Versions: 3.0.0
Reporter: Jorge Leitão
The pseudo code
```
df = context.createDataFrame(...)
df1 = context.createDataFrame(...)
df.join(df1, ...)
```
currently does not work because we clone the {{ExecutionContextState}} from the
context to the `df`, causing the join statement to only have one of the
registered tables in the context state available (as it was not mutated by the
second `createdataFrame`).
We may need an Arc<Mutex<{{ExecutionContextState}}>> so that we have multiple
mutability of their attributes.
