dns_servers = [""] # example, no default

How It Works

Data Directory

Vector requires adata_dir value for on-disk operations. Currently, the only operation using this directory are Vector's on-disk buffers. Buffers, by default, are memory-based, but if you switch them to disk-based you'll need to specify adata_dir.
