![]() ![]() Imagine me standing on the dock waving my handkerchief in the wind, hoping that I someday see your ship on the horizon. I’m sick of waiting around never knowing if I’m going to hear from you this week or if you’re going on another “hiatus.” One Piece, I will wait for you … on Crunchyroll. I’m sick of guessing when you’re going to drop an episode next. But if our relationship is gonna work, I need some consistency from you. I bore them all patiently, because I believe in us, One Piece. Did I complain during the filler arcs? No. You have been on your quest to find the One Piece since 1999 and I have been standing right beside you this whole time.

A test execution of an experimental Airflow Directed Acyclic Graph (DAG) with randomly selected data is performed to evaluate the proposed framework. We present a metadata framework implementation which is based on open-source Big Data technologies, describing its architecture and interconnections with external systems, data model, functions, quality metrics, and templates. In this work, we focus on ETL metadata and its use in driving process execution and present a proprietary approach to the design of the metadata-based process control that can reduce complexity, enhance resilience of ETL processes and allow their adaptive self-reorganization. In order to mitigate this impact and provide resilience of the ETL process, a special Metadata Framework is needed that can manage the design of new data pipelines and processes. In essence, ETL- processes are becoming bottlenecks in such environments due to complexity growth, number of steps in data transformations, number of machines used for data processing and finally, increasing impact of human factors on development of new ETL-processes. Extract-transform-load (ETL) processes play a crucial role in data analysis in real-time data warehouse environments which demand low latency and high availability features for functionality. ![]()
