# Cross CI workflow is triggered on a `pull_request` event.
# It builds the Debezium core before building the Informix connector basing on either the `master` branch or the `pull_request` branch.
# If a `pull_request` with same branch name is present in the Debezium's upstream core repository, then the core build of this `pull_request`
# will be based on `pull_request` branch of user's Debezium core repository.
# Otherwise the core build of this `pull_request` will be based on the `master` branch of Debezium's upstream core repository.
