> [~mujtabachohan] pointed out an "exponential" increase in update time in the size of
the batch.
> Indeed when I look at the code in Indexer.java I see that for each call to postPut or
postDelete we do insert the entire into the local index. (So for a batch of size 10000 we'd
make 10000 index updates 10000 times)
