Validate FaaSr / S3 / local-mode configuration at setup time.

The flare_io.R wrappers read config$s3 and config$run_config directly, so no global state needs initializing. This function exists to fail fast on internally inconsistent configurations and to surface a warning early when AWS credentials are missing under mode="s3".

Usage

initialize_faasr(config)

Arguments

config

FLAREr config list with run_config$use_s3 and optionally run_config$use_faasr.

Value

NULL, invisibly. Errors if use_faasr=TRUE while use_s3=FALSE. Warns if use_s3=TRUE and AWS credentials are not set in the environment.
