⚡ In TableMigration, the performance bottleneck mostly root at collect data file by read the hadoop input file one by one , so I think we can do it in Parallel . In this PR I use the `parquet.metadata.read.parallelism` configraion to control the parallelism . If the `parquet.metadata.read.parallelism` not set or equals 1 , just use the orginal nonparalle api. -- This is an automated message from the Apache Git Service.
