Module: Noiseless::Adapters::ExecutionModules::HttpTransport

Included in:
EsCompatibleExecution, TypesenseExecution
Defined in:
lib/noiseless/adapters/execution_modules/http_transport.rb

Overview

Shared Async::HTTP connection handling for HTTP-based adapters. Host classes must provide a private default_port method.

Constant Summary collapse

TRANSPORT_ERRORS =

Low-level failures the Async::HTTP stack raises when it cannot complete a round-trip with the backend (refused/reset connection, DNS failure, transport timeout). These are wrapped into Noiseless::ConnectionError so callers never have to know which HTTP stack is underneath.

DEFAULT_TIMEOUT =

Default per-operation IO timeout (seconds) for the search backend. This is an idle timeout: every socket read/write must make progress within this window. It bounds a stalled/unresponsive backend without capping the total duration of streaming operations (e.g. bulk import), since data keeps flowing during those. Override per-connection with timeout:.
