Hi MajorProgramming, Deserializing ListProperties can be expensive - nearly equivalent to the cost of deserializing an equivalent number of non-list properties. For exact performance details, I would recommend benchmarking it. A list of size 75 may or may not be problematic, depending on your application.
Also bear in mind that every entry in a ListProperty corresponds to an index entry (unless you marked it as indexed=False), which increases overhead when doing a put(). -Nick Johnson On Fri, Jun 26, 2009 at 3:27 PM, MajorProgamming<sefira...@gmail.com> wrote: > > I was recently watching a Google I/O video (I believe it was by Brett > Slatkin), and I noticed that he was trying to avert the > Deserialization Cost of ListProperties.
