Surgex v2.1.1 Surgex.DataPipe.ForeignDataWrapper
Configures a PostgreSQL Foreign Data Wrapper linkage between two repos.
Specifically, it executes the following steps:
- adds postgres_fdw extension to local repo
- (re)creates server and user mapping based on current remote repo’s config
- copies remote repo’s schema to local repo (named with underscored repo module name)
Everything is executed in one transaction, so it’s safe to use while existing transactions that depend on connection to foreign repo and its schema are running in the system (based on https://robots.thoughtbot.com/postgres-foreign-data-wrapper).
Usage
Refer to Surgex.DataPipe
for a complete data pipe example.
