-- pegasus-bulkloader: pegasus-bulkloader can convert source data to pegasus data and load into pegasus cluster with the [pegasus server 2.1](https://github.com/apache/incubator-pegasus/tree/v2.1) support, see example: [load csv data](https://github.com/pegasus-kv/pegasus-spark/blob/8c585a47e4b618924275c5c1404bdaef9c26f40a/pegasus-spark-bulkloader/src/main/scala/com/xiaomi/infra/pegasus/spark/bulkloader/examples/CSVBulkLoader.scala)
+- pegasus-bulkloader: pegasus-bulkloader can transform a data set to pegasus files and load into pegasus cluster with the feature called "BulkLoad", see example: [load csv data](https://github.com/pegasus-kv/pegasus-spark/blob/8c585a47e4b618924275c5c1404bdaef9c26f40a/pegasus-spark-bulkloader/src/main/scala/com/xiaomi/infra/pegasus/spark/bulkloader/examples/CSVBulkLoader.scala). Since we are still actively improving this feature, we recommend that the Pegasus server version should be higher than v2.2.x.
