[GitHub] ivankelly opened a new pull request #1205: Algorithm to find start point of compacted ledger

ivankelly opened a new pull request #1205: Algorithm to find start point of compacted ledger
URL: https://github.com/apache/incubator-pulsar/pull/1205
 
 
   When reading from a compacted topic ledger, the reader will have to find
   the the first entry whole message id is greater than or equal to the
   position of the cursor. This involves a binary search into the ledger.
   
   This patch implements this binary search, along with basic caching to
   avoid rereading the same entry multiple times.
