Re^6: Consolidating nstore arrays by afoken (Chancellor) on Sep 01, 2017 at 06:51 UTC
According to my documentation for Storable (perl v5.26.0) this output is not possible. nstore can only store one reference. Looks like a beginner trap of Data::Dumper. To dump an array, you have to use `Dumper(\@array)`, not `Dumper(@array)`. If you use the latter, Data::Dumper assumes that you want to see one variable per array element. And in this case, the array(s) contain a total of about 150_000 elements, which explains the 150_000 variables listed by Data::Dumper.

hmm, I don't know what to say. The files are created by storing an array with nstore.
