It appears that there is no "unlimited" value. The default is 2097152 characters, which is equivalent to 4 MB of Unicode string data.

As as already been observed, 17,000 records are hard to use well in the browser. If you are presenting an aggregate view it may be much more efficient to do the aggregation on the server and transfer only a summary in the browser. For example, consider a file system brower, we only see the top of the tree, then emit further requestes as we drill down. The number of records returned in each request is comparatively small. A tree view presentation can work well for large result sets.
