When I tried the data viewer with a huge data frame, I got the impression that limiting it to 100,000 records only waited a few seconds, but with 1 million records it wasn't clear if it was working. |

close #944
Currently, when displaying a data frame in the data viewer, temporary files are written out and read in, which does not work well for huge data frames with more than a few million rows. (related to #619, #837)
I would like to add an option to limit the number of records loaded into the data viewer, as it is often enough to see some of the content without loading all the records into the data viewer.
I would also like to add support for the Apache Arrow Table, which is becoming a strong choice for data frame compatibility when dealing with large numbers of records.
By controlling the number of records to be displayed, a huge Arrow Table can be displayed in the data viewer without stress.
