### Is your feature request related to a problem or challenge? Follow on to https://github.com/apache/arrow-datafusion/pull/6337. Currently when reading an arrow file from a stream, the entire stream is parsed as a file in order to determine the schema: https://github.com/apache/arrow-datafusion/blob/8a47c42096311cf9b6191cfb9d96e2d9ba3a630d/datafusion/core/src/datasource/file_format/arrow.rs#L60-L63 This will result in parsing the stream multiple times (once to determine the schema and again later to actually build RecordBatches from the stream). Can we be more efficient here by only looking as far into the stream as necessary to read the schema? ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
