"Streaming Aggregation" document contains misleading code examples

// instantiate table environment
TableEnvironment tEnv = ...tEnv.getConfig()        // access high-level configuration
  .getConfiguration()   // set low-level key-value options
  .setString("table.exec.mini-batch.enabled", "true")  // enable mini-batch optimization
  .setString("table.exec.mini-batch.allow-latency", "5 s") // use 5 seconds to buffer input records
  .setString("table.exec.mini-batch.size", "5000"); // the maximum number of records can be buffered by each aggregate operator task
