I'm interested in using ExternalFileField to store a field "popularity" that is
being updated frequently.
However ExternalFileField seems to be a pretty obscure feature. Have a few
questions:
1) Can anyone share your experience using it?
2) What is the most efficient way to update the external file?
For example, the file could look like:
1=12 // the document with uniqueKey 1 has a popularity of 12//
2=4
3=45
5=78
Now the popularity of document 1 is updated to 13:
- What is the best way to update the file to reflect the change? Isn't this an
O(n) operation?
- How to deal with concurrent updates to the file by multiple threads?
Would this method of using an external file scale?
Thanks.
