Summary
Add a new FAQ entry to the Flink Doris Connector docs (English/Chinese, dev/4.x) for the
I/O exception (java.net.SocketException) ... Broken pipeerror that users may encounter when syncing large tables (e.g. Oracle) via Flink CDC.The FAQ explains the root cause (single Stream Load data volume exceeding the BE-side limit) and lists three mitigations:
streaming_load_max_mb.sink.enable.batch-mode=true).--oracle-conf scan.incremental.snapshot.enabled=true(experimental).Also references the upstream Flink CDC FAQ for further reading.
