Mike Seddon created ARROW-11013: ----------------------------------- Summary: [Rust] CSV Reader cannot handle leading/trailing WhiteSpace Key: ARROW-11013 URL: https://issues.apache.org/jira/browse/ARROW-11013 Project: Apache Arrow Issue Type: Bug Components: Rust, Rust - DataFusion Affects Versions: 2.0.0 Reporter: Mike Seddon
Currently the CSV Reader assumes very clean input data which does not have things like leading spaces. This means parsing data like the TPC-H 'answers' set from the databricks/tpch_dbgen repo does not work (like below). Spark uses the Univocity parser library provides the options 'ignoreLeadingWhitespace' and 'ignoreTrailingWhitespace' which would help fix this issue. ``` l|l|sum_qty|sum_base_price|sum_disc_pricesum_chargeavg_qtyavg_priceavg_disccount_order A|F|37734107.00|56586554400.73|53758257134.87|55909065222.83|25.52|38273.13|0.05| 1478493 ``` -- This message was sent by Atlassian Jira (v8.3.4#803005)
