Store.needsCompaction介绍

[英]See if there's too much store files in this store
[中]看看这家店的文件是否太多

/**
 * Checks every store to see if one has too many
 * store files
 * @return true if any store has too many store files
 */

  // or changing the memstore. Let us release it before calling
  // notifyChangeReadersObservers. See HBASE-4485 for a possible
  // deadlock scenario that could have happened if continue to hold
  // the lock.

 }
 // Tell listeners of the change in readers.
