Database Migration Service - Estimate the size of data from RDS to S3 with compression using parquet files and without compression

Is there a way to estimate the size of the data to be migrated from RDS where our source is MYSQL and destination being S3, exporting all the data to S3 using Amazon DMS task (with and without compression)

Here is my connection attributes for the destination endpoint

addColumnName=true;bucketFolder=buketfolder;bucketName=bucketname-s3;compressionType=GZIP;csvDelimiter=,;csvRowDelimiter=\n;dataFormat=parquet;datePartitionEnabled=false;
