Phoenix批量提交優化，官網的demo

1 Phoenix的批量insert官網代碼，最佳實踐

try (Connection conn = DriverManager.getConnection(url)) {
  conn.setAutoCommit(false);
  int batchSize = 0;
  int commitSize = 1000; // number of rows you want to commit per batch.  
  try (Statement stmt = conn.prepareStatement(upsert)) {
    stmt.set ... while (there are records to upsert) {
      stmt.executeUpdate(); 
      batchSize++; 
      if (batchSize % commitSize == 0) { 
        conn.commit(); 
      } 
   } 
 conn.commit(); // commit the last batch of records 
 }

　　

2 解讀代碼

　　循環的過程中，每1000條數據批量提交一次，不足1000的在循環外圍最后提交，所以保證了，所有數據最終都是會被提交.
