• cloud_functions/ztf/tag/tests -> cloud_run/ztf/store_BigQuery/tests
• cloud_functions/ztf/tag -> cloud_run/ztf/tag
  • In addition to identifying basic categorizations, main.py also publishes messages with the top-level key: "alert_lite" to the ztf-lite Pub/Sub topic
• cloud_run/ztf/classify_snn/
  • deploy.sh
    • updated trigger topic: ztf-tagged -> ztf-lite
  • main.py
    • updated functions to accommodate incoming message format
• cloud_run/ztf/variability/
  • deploy.sh
    • updated trigger topic: ztf-tagged -> ztf-lite
    • updated variable names
  • main.py
    • updated functions to accommodate incoming message format
• setup_broker/ztf/
  • setup_gcp.py
    • script no longer creates ztf-lite Pub/Sub resources
  • setup_broker.sh
    • updates Pub/Sub resources created in this script
    • updates the deployment of cloud run/functions

Removed

• cloud_functions/ztf/lite

Added

• setup_broker/ztf/templates/ps_ztf_lite_smt.yaml
  • This file defines the function create_lite_alert which is used by the Pub/Sub topic ztf-lite to apply a single message transform (SMT) to incoming Pub/Sub messages. This SMT effectively replaces the ztf-lite Cloud Run service
