Migration v1 to v2

Single binary

First deploy v1

Note: Needs persistence enabled otherwise data will be lost after restart

helm upgrade \
  pyroscope \
  ./operations/pyroscope/helm/pyroscope \
  --install \
  --set architecture.storage.v1=true \
  --set architecture.storage.v2=false \
  --set pyroscope.persistence.enabled=true

Step: 2: Deploy v2 and enable dual ingest

Note: The python command will switch to the v2 read path for data ingested 10 minutes after it is run.

helm upgrade \
  pyroscope \
  ./operations/pyroscope/helm/pyroscope \
  --set architecture.storage.v1=true \
  --set architecture.storage.v2=true \
  --set pyroscope.persistence.enabled=true \
  --set architecture.storage.migration.queryBackendFrom=$(python3 -c "import datetime; print((datetime.datetime.now(datetime.UTC)+ datetime.timedelta(minutes = 10)).strftime('%Y-%m-%dT%H:%M:%SZ'))")

Step 3: Remove v1 components

Once data before Step 2 is no longer relevant, we can get rid of the v1 components. This will loose all data before Step 2.

helm upgrade \
  pyroscope \
  ./operations/pyroscope/helm/pyroscope \
  --set architecture.storage.v1=false \
  --set architecture.storage.v2=true \
  --set pyroscope.persistence.enabled=true

Micro-Services

First deploy v1

Note: Needs persistence enabled otherwise data will be lost after restart
Note: --set architecture.overwriteResources.requests.cpu=10m allow this to be tested without allocation many resources, this should not be used in production

helm upgrade \
  pyroscope \
  ./operations/pyroscope/helm/pyroscope \
  --install \
  --set architecture.microservices.enabled=true \
  --set architecture.overwriteResources.requests.cpu=10m \
  --set minio.enabled=true \
  --set architecture.storage.v1=true \
  --set architecture.storage.v2=false \
  --set pyroscope.persistence.enabled=true

Step: 2: Deploy v2 and enable dual ingest

Note: The python command will switch to the v2 read path for data ingested 10 minutes after it is run.

helm upgrade \
  pyroscope \
  ./operations/pyroscope/helm/pyroscope \
  --set architecture.microservices.enabled=true \
  --set architecture.overwriteResources.requests.cpu=10m \
  --set minio.enabled=true \
  --set architecture.storage.v1=true \
  --set architecture.storage.v2=true \
  --set pyroscope.persistence.enabled=true \
  --set architecture.storage.migration.queryBackendFrom=$(python3 -c "import datetime; print((datetime.datetime.now(datetime.UTC)+ datetime.timedelta(minutes = 10)).strftime('%Y-%m-%dT%H:%M:%SZ'))")
