Conversation
Use kafka_max_message_size_upper_limit_bytes to clamp max_bytes and max_batch_size in fetch memory allocation instead of the full shard fetch memory budget. This prevents a single partition with an inflated max.message.bytes (e.g. UINT32_MAX) from monopolizing the entire shard's fetch memory, which can starve other partitions and cause fetch timeouts. (cherry picked from commit 2b2c4b3)
