The redesign of the earlier GCP setup helped ship price-performance enhancements. Yggdrasil decreased ingestion and processing prices by roughly 60% whereas additionally decreasing operational overhead by way of a extra direct, event-driven pipeline.
Implement real-time information ingestion
After establishing the lakehouse structure, the following step targeted on enabling real-time information ingestion from Yggdrasil’s operational databases into the uncooked information layer of the lakehouse. The target was to seize and ship transactional modifications as they happen, ensuring that downstream analytics and reporting mirror essentially the most up-to-date data.
To realize this, GOStack deployed Debezium Server Iceberg, an open-source venture that integrates change information seize (CDC) immediately with Apache Iceberg tables. It was deployed as Argo CD functions on Amazon EKS and used Argo’s GitOps-based mannequin for reproducibility, scalability, and seamless rollouts.
This structure supplies an environment friendly ingestion pathway – streaming information modifications immediately from the supply system’s outbox tables into the Apache Iceberg tables registered within the AWS Glue Information Catalog and bodily saved on Amazon S3, bypassing the necessity for intermediate brokers or staging providers. By writing information within the Iceberg desk format, the ingestion layer maintained transactional ensures and quick question availability by way of Amazon Athena.

As a result of Yggdrasil’s supply techniques emitted outbox occasions containing Avro data, the workforce carried out a customized outbox-to-Avro transformation inside Debezium. The outbox desk saved two key elements:
- The Avro schema definition
- The JSON-encoded payload of every file
The customized transformation module mixed these components into legitimate Avro data earlier than persisting them into the goal Iceberg tables. This strategy preserved schema constancy and verified compatibility with downstream processing instruments.
To dynamically route incoming change occasions, the workforce leveraged Debezium’s occasion router configuration. Every file was routed to the suitable Apache Iceberg desk (backed by Amazon S3) based mostly on matter and metadata guidelines, whereas desk schemas and partitioning had been ruled on the AWS Glue facet to keep up stability and alignment with the lakehouse’s information group requirements.
This setup helped ship low-latency ingestion with end-to-end streaming from database outbox to S3-based Iceberg tables in close to actual time. The workforce managed operations finish to finish on Amazon EKS utilizing Helm charts deployed through Argo CD in a GitOps mannequin for absolutely declarative, version-controlled operations. ACID-compliant Iceberg writes verified that partially written information couldn’t corrupt downstream analytics. The modular transformation logic allowed future growth to new supply techniques or occasion codecs with out rearchitecting the ingestion pipeline.
This Debezium Server resolution supplies quick, real-time information ingestion. GOStack considers it an interim structure. In the long run, the ingestion pipeline will evolve to make use of Amazon Managed Streaming for Apache Kafka (Amazon MSK) because the central occasion spine. Debezium connectors will act as producers, publishing change occasions to Apache Kafka subjects, whereas Apache Flink functions will eat, course of, and write information into Iceberg tables.
This deliberate evolution towards a Kafka-based streaming structure verifies Yggdrasil’s lakehouse stays not solely scalable and cost-efficient as we speak, but in addition future-ready – able to supporting richer streaming analytics and broader information integration eventualities because the group grows.

The light-weight Cloud Run capabilities that beforehand dealt with extraction duties – pulling information from file shares, SharePoint, Google Sheets, and varied third-party APIs – had been re-implemented utilizing AWS Lambda. These Lambda capabilities now combine with the identical exterior techniques and write information immediately into Iceberg tables.
For extra advanced processing, earlier Apache Spark functions operating on Dataproc had been migrated to Amazon EMR with minimal code modifications. This allowed it to protect the prevailing transformation logic whereas benefiting from the managed scaling capabilities of EMR and improved value management on AWS.
Over time, these processes will likely be steadily refactored and consolidated into containerized workflows on the EKS cluster, absolutely orchestrated by Argo Workflows. This phased migration permits Yggdrasil to maneuver workloads to AWS rapidly and decommission GCP assets sooner, whereas nonetheless leaving room for steady enchancment and modernization of the info system over time.
Lastly, a variety of analytical transformations that beforehand lived as BigQuery saved procedures and scheduled queries, that had been now rebuilt as modular dbt fashions executed with dbt-athena. This shift made transformation logic extra clear, maintainable, and version-controlled, enhancing each developer expertise and long-term governance.
Modernizing the transformation layer
With the ingestion pipelines migrated to AWS, GOStack turned its focus to simplifying and modernizing Yggdrasil’s analytical transformations. Slightly than replicating the earlier stored-procedure–pushed strategy, the workforce rebuilt the transformation layer utilizing dbt to assist enhance maintainability, lineage visibility, orchestration, and long-term governance.As a part of this redesign, a number of information fashions had been reshaped to suit the brand new lakehouse structure. Essentially the most important effort concerned rewriting a important Spark-based monetary transformation right into a set of SQL-driven dbt fashions. This shift not solely aligned the logic with the lakehouse design but in addition eliminated the necessity for long-running Spark clusters, serving to generate operational and price financial savings.For the curated information layers, changing the legacy warehouse, GOStack consolidated quite a few scheduled queries and saved procedures into structured dbt fashions. This supplies standardized, version-controlled transformations and clear lineage throughout the analytical stack.
Orchestration was simplified as nicely. Beforehand, coordination was cut up between Apache Airflow for Spark workloads and scheduled queries analytical transformations, creating operational friction and dependency dangers. Within the new structure, Argo Workflows on Amazon EKS orchestrates dbt fashions centrally, consolidating the transformation logic inside a single workflow engine. Whereas most transformations nonetheless run on time-based schedules as we speak, the system now helps event-driven execution by way of Argo Occasions, giving the chance to progressively undertake trigger-based workflows because the transformation layer evolves.
This unified orchestration framework can deliver a number of advantages:

The transfer to dbt and Athena not solely simplified operations but in addition helped pave the way in which for quicker iteration, easier governance, and better developer productiveness throughout the info surroundings.
Lakehouse efficiency optimizations
Whereas efficiency tuning is an ongoing journey, as a part of the transformation redesign, GOStack made few performance-oriented tweaks to ensure Athena queries could be quick and cost-efficient. The Apache Iceberg tables had been saved in Parquet with ZSTD compression, offering sturdy learn efficiency and lowering the quantity of information scanned by Athena.
Partitioning methods had been additionally aligned to precise entry patterns utilizing Iceberg’s native partitioning. Uncooked information zones had been partitioned by ingestion timestamp, enabling environment friendly incremental processing. Curated information used business-driven partition keys, comparable to participant or sport identifiers and date dimensions, to assist optimize analytical queries. These designs made certain Athena may prune unneeded information and persistently scan solely the related partitions.
Iceberg’s native partitioning options, together with transforms comparable to bucketing and time slicing, substitute conventional Hive partitioning patterns. As a result of Iceberg manages partitions internally in its metadata layer, not all Glue or Athena partition constructs apply. Counting on Iceberg’s native partitioning helps present predictable pruning and constant efficiency throughout the lakehouse with out introducing legacy Hive behaviors.
To deal with the excessive quantity of small recordsdata produced by real-time ingestion, GOStack enabled AWS Glue Iceberg compaction. This robotically merges small Parquet recordsdata into bigger segments, serving to enhance question efficiency and cut back metadata overhead with out handbook intervention.
Allow governance
The workforce adopted AWS Lake Formation as the first governance layer for the curated zone of the lakehouse, leveraging Lake Formation hybrid entry mode to handle fine-grained permissions alongside present IAM-based entry patterns. This hybrid mode supplies an incremental and versatile pathway to undertake Lake Formation with out forcing a full migration of legacy permissions or inside pipeline roles, making it a really perfect match for Yggdrasil’s phased modernization technique.
