[jira] [Created] (ARROW-8265) [Rust] [DataFusion] Table API
collect() should not require context
Andy Grove created ARROW-8265:
---------------------------------
Summary: [Rust] [DataFusion] Table API collect() should not require context
Key: ARROW-8265
URL: https://issues.apache.org/jira/browse/ARROW-8265
Project: Apache Arrow
Issue Type: Bug
Components: Rust, Rust - DataFusion
Reporter: Andy Grove
Assignee: Andy Grove
Fix For: 0.17.0
The Table API requires the context to be passed into the collect() method which leads to this odd code.
{code:java}
let results = ctx.table("alltypes_plain")?
.filter(col("c12").gt(&lit_f64(0.5)))?
.aggregate(vec![col("c1")], vec![min(col("c12"))])?
.collect(&mut ctx, 1024)?; {code}
Since the table comes from the context, it should not be necessary to pass the context back in.
