  • Environment variable: TARGET_GCS_BUCKET_NAME

The name of the GCS Bucket to sync the stream to


  • Environment variable: TARGET_GCS_CREDENTIALS_FILE
  • Default Value: $MELTANO_PROJECT_ROOT/client_secrets.json

The fully resolved path to the credentials json file. By default we will look in the meltano project directory root for a file called client_secrets.json


  • Environment variable: TARGET_GCS_DATE_FORMAT
  • Default Value: %Y-%m-%d

The date formate for the export date used in the bucket key path


  • Environment variable: TARGET_GCS_KEY_PREFIX
  • Default Value: meltano/${MELTANO_EXTRACT__LOAD_SCHEMA}/

This is the base key prefix which lets you define where the stream will write to in the bucket. By default, we use meltano/${MELTANO_EXTRACT__LOAD_SCHEMA}/ which is derived from the tap. For example tap-jira would end up in meltano/tap_jira/...


  • Environment variable: TARGET_GCS_KEY_NAMING_CONVENTION
  • Default Value: {stream}/export_date={date}/{timestamp}.jsonl

This is the naming convention for the key. Available values in the format string are stream (stream name), date, timestamp. By default this naming convention uses hive style partitioning
