Introducing Pyroscope 2.0: faster, more cost-effective continuous profiling at scale
Pyroscope 2.0 brings major cost reductions to continuous profiling at scale through architectural changes that eliminate write-path replication and cut symbol storage by up to 95%.
What: Pyroscope 2.0 is an open source continuous profiling database with a redesigned architecture featuring stateless queriers that scale elastically and native support for OpenTelemetry's alpha Profiles signal. It has already processed 19.5 petabytes of data in Grafana Cloud since April 2025.
Why it matters: Continuous profiling has traditionally been expensive to operate at scale due to storage and replication costs, making this cost breakthrough significant for teams wanting production profiling without breaking their infrastructure budget.
Takeaway: Developers running profiling infrastructure or looking to adopt continuous profiling can evaluate Pyroscope 2.0 as an open source alternative with dramatically lower storage costs.
Decoder
- Continuous profiling: Ongoing collection of performance data showing what code is consuming CPU, memory, and other resources in production systems, rather than one-time profiling sessions
- Write-path replication: Duplicating data as it's being written to the database for redundancy, which increases storage costs and write latency
- Symbol storage: Storage of debugging symbols that map memory addresses back to function names and source code locations in profiling data
- OpenTelemetry Profiles signal: An alpha-stage specification within the OpenTelemetry observability framework for standardizing how profiling data is collected and transmitted
