Is Dapper's pipelining supported?

[bgrainger]

Dapper supports a "pipelining" feature: https://riptutorial.com/dapper/example/18/performing-operations-against-multiple-sets-of-input

A user reports an exception when trying to use it with MySqlConnector: DapperLib/Dapper#1469

Is this something that should be expected to work, or is it not actually supported by the MySQL protocol?

Dapper's pipelining works by executing up to 100 MySqlCommand objects "simultaneously" (using ExecuteNonQueryAsync), then recycling the commands once they complete.

This appears to be a breaking change when switching from MySql.Data to MySqlConnector because the async operations actually complete synchronously, making it just a synchronous loop.

As per DapperLib/Dapper#1469 (comment), I'd say that Dapper's pipelining is not supported, and recommend using MySqlBatch instead.
