Work Description: riazela commented on pull request #8951: [BEAM-7545] Adding RowCount to TextTable
URL: https://github.com/apache/beam/pull/8951
This change enables row count estimation for text table. It will first read couple of rows from the files in the directory and then using the length of those rows and the size of the files estimates the size of table.
