GoGuardian, an education technology platform, faced significant challenges in managing its digital learning environment due to the COVID-19 pandemic. The company needed a unified database solution that could handle high-throughput traffic, support upsert use cases, and provide fast aggregate reads. After exploring various options such as SQL, Druid, Phoenix, BigQuery, Presto, Amazon Athena, Spanner, and SingleStoreDB, GoGuardian discovered SingleStoreDB as the ideal solution. This cloud-native unified database offered row and column data stores in the same database, high availability, speed, friendly support, and supported GoGuardian's upsert use case. With SingleStoreDB, GoGuardian achieved an average throughput of 2.49 million events per minute, write throughput of 750,000 per second, read throughput of 400 per minute, and <30ms latency for some queries, resulting in a cost savings of $30,000 per month compared to legacy solutions.
