Frequently asked questions
This page provides answers to some frequently asked questions about Currents.
How do I get historical data?
Currents is a real-time, live data stream, which means that events can’t be replayed. However, you can store Currents data in a data warehouse such as Amazon S3 or Microsoft Azure Blob Storage, so you can act on past events as you see fit. Data is retained for 30 days, but for more historical data, you can query Snowflake.
Why does Currents output data in the Avro format, not JSON?
Avro, unlike schema-less JSON, natively supports schema evolution. You’ll also benefit from the ability to send Avro files with less bandwidth and saved storage space because Avro is highly compressible.

Where should I store this data for querying?
Braze is partnered with several data warehouses you can store your data in for querying. We recommend using:
