trino connector to flat files

I am trying to create trino connector to query the data available in a flat file (say a text file with 100 records, each record is separated by newline and each column separated by comma). Trino documentation page (https://trino.io/docs/current/connector/localfile.html) shows how to create a connector for LocalFile but it works only for HTTP logs. Can any one help me. Thanks in advance.

As you already mentioned, it's only for HTTP logs and columns are hard-coded:

private static final List<ColumnMetadata> COLUMNS = ImmutableList.of(
                SERVER_ADDRESS_COLUMN,
                new ColumnMetadata("timestamp", createTimestampWithTimeZoneType(3)),
                new ColumnMetadata("client_address", createUnboundedVarcharType()),
                new ColumnMetadata("method", createUnboundedVarcharType()),
                new ColumnMetadata("request_uri", createUnboundedVarcharType()),
                new ColumnMetadata("user", createUnboundedVarcharType()),
                new ColumnMetadata("agent", createUnboundedVarcharType()),
                new ColumnMetadata("response_code", BIGINT),
                new ColumnMetadata("request_size", BIGINT),
                new ColumnMetadata("response_size", BIGINT),
                new ColumnMetadata("time_to_last_byte", BIGINT),
                new ColumnMetadata("trace_token", createUnboundedVarcharType()));
