updates happen within a single transaction, there was a lot of wasted encode/decode overhead due to segment merges. This code buffers updates in memory and writes out larger level-0 segments. It only works when documents are presented in ascending order by docid. Comparing a test set running 100 documents per transaction, the total runtime is cut almost in half.
