This comparison addresses a unique situation in the data warehouse space. Rockset was a strong real-time analytics database that excelled at sub-second SQL queries on streaming and raw data, but OpenAI acquired the company in June 2024 and it is no longer available as a standalone product. Google BigQuery remains one of the most widely adopted cloud data warehouses, offering serverless analytics at petabyte scale with flexible pricing and expanding AI capabilities. For teams currently evaluating data warehouse and analytics platforms, BigQuery is the active, fully supported option. Teams that specifically need Rockset's sub-second operational query latency should look at specialized real-time engines rather than expecting BigQuery to fill that exact niche.

This verdict is based on general use cases. Your specific requirements, existing tech stack, and team expertise should guide your final decision.
No. OpenAI acquired Rockset in June 2024 to integrate its real-time indexing and retrieval technology into OpenAI's product infrastructure. Rockset is no longer available for new customers as an independent analytics database. Existing Rockset customers were transitioned as part of the acquisition. Teams that were evaluating Rockset for real-time analytics need to consider alternative platforms such as Google BigQuery, ClickHouse, Apache Druid, or Elasticsearch depending on their latency and query pattern requirements.
BigQuery supports real-time analytics through streaming inserts, Pub/Sub subscriptions, and continuous queries, but it is fundamentally optimized for analytical throughput rather than sub-second operational serving. Rockset was purpose-built for low-latency queries on streaming data, delivering sub-second response times for application-facing workloads. BigQuery queries typically return in seconds to minutes depending on data volume. For teams that need BigQuery's analytical power alongside low-latency serving, Google recommends pairing BigQuery with Bigtable or Memorystore for the serving layer.
BigQuery offers a free tier with 10 GB of storage and 1 TiB of queries per month. Beyond that, on-demand pricing charges $6.25 per TiB of data scanned. For a mid-size team scanning 5 to 20 TB per month, query costs range from roughly $30 to $125 per month. Teams with predictable workloads can reduce costs by 30 to 60 percent by switching to capacity-based Editions, which offer slot reservations starting at $0.04 per slot-hour for Standard, $0.06 for Enterprise, and $0.10 for Enterprise Plus. Active storage costs $0.02 per GB per month, dropping to $0.01 per GB for data untouched for 90 days.
The closest alternatives depend on the specific workload pattern. For real-time OLAP queries on event streams, ClickHouse and Apache Druid deliver low-latency analytical performance on high-volume data. For search and retrieval workloads similar to what OpenAI acquired Rockset for, Elasticsearch and Apache Pinecone handle full-text and vector search at scale. BigQuery serves teams that prioritize analytical depth and GCP integration over sub-second latency. Materialize and RisingWave offer streaming SQL for teams that need continuously updated query results.
BigQuery is not a direct replacement for Rockset's application-facing query use case. Rockset was optimized for serving live application queries with sub-second latency on continuously ingested data. BigQuery is optimized for analytical workloads where query times of a few seconds are acceptable. Teams migrating from Rockset for operational serving should evaluate ClickHouse, Elasticsearch, or a dedicated serving layer in front of BigQuery rather than expecting BigQuery to match Rockset's latency profile for high-concurrency, low-latency application queries.
