 - `--secure` – If specified, will connect to server over secure connection (TLS). You might need to configure your CA certificates in the [configuration file](#configuration_files).

 Same as [Protobuf](#protobuf) but for storing/parsing single Protobuf message without length delimiters.

+## ProtobufList {#protobuflist}
+
+Similar to Protobuf but rows are represented as a sequence of sub-messages contained in a message with fixed name "Envelope".
+
+Usage example:
+
+``` sql
+SELECT * FROM test.table FORMAT ProtobufList SETTINGS format_schema = 'schemafile:MessageType'
+```
+
+``` bash
+cat protobuflist_messages.bin | clickhouse-client --query "INSERT INTO test.table FORMAT ProtobufList SETTINGS format_schema='schemafile:MessageType'"
+```
+
+where the file `schemafile.proto` looks like this:
+
+``` capnp
+syntax = "proto3";
+message Envelope {
+  message MessageType {
+    string name = 1;
+    string surname = 2;
+    uint32 birthDate = 3;
+    repeated string phoneNumbers = 4;
+  };
+  MessageType row = 1;
+};
