 `GlobalExecutionOptions` is used to configure the global execution options shared by all flows. It has the following fields:
 
-*   `source_max_inflight_rows` (type: `int | None`, default: `256`): The maximum number of concurrent inflight rows for all source operations.
+*   `source_max_inflight_rows` (type: `int | None`, default: `1024`): The maximum number of concurrent inflight rows for all source operations.
 *   `source_max_inflight_bytes` (type: `int | None`, default: `None`): The maximum number of concurrent inflight bytes for all source operations.
 
 See also [flow definition docs](/docs/core/flow_def#control-processing-concurrency) about why it's necessary to control processing concurrency, and how to configure it on per-source basis.
