1) Generate a private key and certificate signing request:

openssl genrsa -out ios_distribution.key 2048
openssl req -new -key ios_distribution.key -out ios_distribution.csr -subj '/[email protected], CN=Example, C=US'

2) Upload CSR to apple at: https://developer.apple.com/account/ios/certificate/create
   - choose Production -> App Store and Ad Hoc

3) Download the resulting ios_distribution.cer, and convert it to .pem format:

• 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)
