A follow up of https://github.com/apache/incubator-gluten/pull/11090, broadcast table is usually a small table, so we don't serialize to cudf format in the first step, just convert it to cudf table, this might be expensive for string data type. May optimize to serialize to cudf format and deserialize to cudf table as hash shuffle reader, copy the buffer to deserialize to cudf::table. Test in local with TPCDS Q95. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
