## Buyer Intent Signals
Problems: How to handle schema evolution in data lakes | Manual Data Lake Management: Storing and managing data in raw formats (Parquet, Avro) on cloud storage (S3, ADLS) without a transactional layer, manually handling schema and consistency. | Custom ETL Scripts: Relying on custom-built ingestion and cleaning scripts to maintain data integrity in a standard data lake.
Solutions: What is a lakehouse architecture? | ACID transactions on S3 | Best table format for Apache Spark | Open source big data storage formats | Traditional Data Warehousing: Using traditional relational databases or cloud data warehouses for all workloads, despite higher costs for massive unstructured data.
