Legacy batch-based architectures in brokerages and trading firms are increasingly inadequate as markets extend toward 24-hour trading. Pre-trade risk checks and intraday margin calculations both require high-throughput streaming ingestion combined with sub-second analytical query performance under high concurrency — a combination that mainframes, Vertica, single-node databases, KDB, Snowflake, Databricks, and Iceberg each fail to deliver for different reasons. The recommended approach is augmentation rather than replacement: inserting a compute-optimized database (SingleStore) at the application layer to serve the real-time query tier while leaving existing infrastructure intact. A Fortune 25 financial institution achieved 10–20ms query results across 20 years of portfolio history using this pattern. Standard SQL compatibility is highlighted as a key operational advantage over proprietary systems like KDB.
