Indexing a Data Lake for Online Point Queries

Companies like Spotify need environments that can access vast amounts of data with low latency for online services. To achieve this, an indexing strategy is required that can efficiently handle online Point Queries while still leveraging the existing data lake structure.

Data lakes are advantageous for large-scale data storage, but they have limitations in meeting the requirements of online services that need to quickly find specific records. To address this, an indexing layer is added to the data lake to optimize data access performance.
