I can share the data.. but it would be quicker for you to just
pull out some
random text from anywhere you like.
OK, I hear you. I'll pull together some test data ... thanks.
Also.. upon reflection I'm not certain using compression inside
the index is
really a valuable process without lazy loading anyway. The time-
cost of
decompression when iterating hits reduces the overall
effectiveness of the
index. This is obviously solved by lazy loading (for searches)
and I am
excited about this feature being added. Obviously it depends on the
use-case, but in mine I realised that storing large amounts of
data in the
index is just not the right way to do things. So I changed my
architecture
so that the larger amounts of data are stored (and compressed)
elsewhere,
then brought back in when I need to update a document.
Of course all my problems would be solved if I had lazy loading
AND field
updating :)
Compleletely agreed! Lazy loading & specific field selection on
loading a doc, have been addressed ... but field updating in the
presence of compressed fields hasn't yet been addressed (I
think). I'll raise this use case on the java-dev list.
Mike
