- The first member of Vietnam data team. Working directly with CTO. Recommend, explain,POC the good architect and solution.- Code base full new platform that migrate ETL using digdag and MapReduce to airflow and BigQuery. - We have 98TB in S3, hourly data above 1GB. With power of BQ, the heaviest task which process with 64 core in MapReduce reduce from 3-4 hour to 30 minutes. I use a custom of Hive for partition step to reduce partition time from 1 hour to 6-10 minutes.
