Engineering · Data ScienceHow we seamlessly migrated high volume real-time streaming traffic from one service to another with zero data loss and duplication
In the world of high-volume data processing, migrating services without disruption is a formidable challenge. At Grab, we recently undertook this task by splitting one of our backend service's stream read and write functionalities into two separate services. Discover how we conducted this transition with zero data loss and duplication using a simple switchover strategy, along with rigorous validation mechanisms.

Engineering · Data ScienceMetasense V2: Enhancing, improving and productionisation of LLM powered data governance
In the initial article, we explored the integration of Large Language Models (LLM) to automate metadata generation, addressing challenges like limited customisation and resource constraints. This integration enabled efficient column-level tag classifications and data sensitivity tiering. With the model initially scanning over 20,000 entries, we identified areas for improvement post-rollout. These advancements have significantly reduced manual workloads, increased accuracy, and bolstered trust in our data governance processes.
