  "account": "The small-file lakehouse explosion occurs when high-frequency streaming pipelines generate thousands of tiny Parquet files directly into Apache Iceberg or Delta tables. In 30-second commit cycles, the table metadata trees grow to gigabytes, overwhelming distributed query engines such as Trino and DuckDB, causing query timeouts during file discovery. Despite the operational crisis, data engineering teams adopted real-time lakehouses to meet the demand for immediate data freshness for operational dashboards and agentic analytics.",
