[GitHub] rdhabalia opened a new pull request #1938: [bk-gc] Prevent OOM: Restrict number of entry-loggers extraction

rdhabalia opened a new pull request #1938: [bk-gc] Prevent OOM: Restrict number of entry-loggers extraction
URL: https://github.com/apache/bookkeeper/pull/1938
 
 
   ### Motivation
   
   Due to #1937, bookies couldn't run GC for a week that accumulates > 10K entry-logger files on the disk. After restarting bookie, GC gets trigger and GC tries to extract and loads all data into memory which eventually causes OOM in bookie and bookies keep restarting.
   
   ### Changes
   
   Bookie should extract entry-loggers in chunk to avoid memory pressure and OOM issues.
