Notes from Elasticsearch Engineer II training
View gist:2381ca5f8136f72b3718ca8353a7d5cc
  • Elasticsearch Internals
    • Lucene Indexing
      • Java Library
      • Shard
        • A shard is an instance of Lucene
        • max # of documents in a shard is Integer.MAX_VALUE - 128
        • clients do not refer to shards directly (use index instead
        • What's in a shard?
          • indexed document gets analyzed, put in buffer
  • buffer defaults to 10% of node heap (set with indices.memory.index_buffer_size)
