📂 Project: Dev

Session Goal

The primary aim of this session was to refactor a legacy accounting timeseries codebase, focusing on architectural improvements and specific implementations related to transaction processing and reporting.

Key Activities

  • Developed a comprehensive refactoring plan to decouple processing logic and enhance code architecture, addressing wide-vs-long column mismatches.
  • Designed an intermediate layer for time-series data processing, detailing strategies for data ingestion, aggregation, and reporting.
  • Implemented a materialization layer for processing canonical ledger data into time-series aggregates.
  • Integrated various ingest ideas into a build_ledger_base function, enriching ledger data and supporting ETL pipelines.
  • Explored data layer interactions to understand the relationship between atomic ledger data and time-series bundles.

Achievements

  • Successfully refactored the middle layer responsibilities, mapping legacy code to new locations with concrete function signatures.
  • Enhanced the overall architecture of the accounting codebase, improving transaction processing and reporting capabilities.

Pending Tasks

  • Further testing and validation of the refactored codebase to ensure robustness and accuracy.
  • Complete integration of the materialization layer with existing systems and workflows.
