[jira] [Updated] (ARROW-6341) [Python] Implement low-level bindings
for Dataset
[ https://issues.apache.org/jira/browse/ARROW-6341?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Francois Saint-Jacques updated ARROW-6341:
------------------------------------------
Description:
The following classes should be accessible from Python:
* class DataSource
* class DataSourceDiscovery
* class Dataset
* class ScanContext, ScanOptions, ScanTask
* class ScannerBuilder
* class Scanner
The end result is reading a directory of parquet files as a single stream. One should be able to re-implement [https://github.com/apache/arrow/pull/5720] in python.
