[tarantool-patches] [PATCH] replication: automatic skip duplicating rows in replication

[Konstantin Osipov]

Konstantin, checking the configuration option for every
conflicting row is too much overhead.

Please instead implement a trigger which would push any change in
box.cfg to a global variable in replication module.

> +				 */
> +				if (e->type == &type_ClientError &&
> +				    box_error_code(e) == ER_TUPLE_FOUND &&
> +				    cfg_geti("replication_skip_conflict"))
> +					diag_clear(diag_get());
> +				else
> +					diag_raise();
> +			}

I'm talking about this bit.

Thanks!
