* 集群服务端对表设置了[表级写流量控制](/administration/throttling#服务端流控)。
* 此时该表的瞬时流量(在这1秒内的写入操作数)达到了阈值,触发了reject流控操作,返回`ERR_BUSY`错误码。
-# Java客户端工具
-
-Pegasus Java客户端还提供了`PegasusCli`工具,支持简单的读写操作。
-
-使用mvn编译:
-```
-mvn clean package -DskipTests
-```
-
-编译后,在target文件夹下可以找到压缩包`pegasus-client-{version}-bin.tar.gz`,解压后得到`pegasus-client-{version}`文件夹,进入该文件夹,就可以找到PegasusCli工具。
-
-用法:
-```
-USAGE: PegasusCli <config-path> <table-name> <op-name> ...
-
- <config-path> should be:
- - zookeeper path : zk://host1:port1,host2:port2,host3:port3/path/to/config
- - local file path : file:///path/to/config
- - java resource : resource:///path/to/config
-
- <op-name> should be:
- - get <hash-key> <sort-key>
- - set <hash-key> <sort-key> <value> [ttl_seconds]
- - del <hash-key> <sort-key>
- - multi_get <hash_key> [sort_key...]
- - multi_get_sort_keys <hash_key>
- - multi_set <hash_key> <sort_key> <value> [sort_key value...]
- - multi_del <hash_key> <sort_key> [sort_key...]
- - incr <hash_key> <sort_key> [increment]
- - scan <hash_key> [start_sort_key] [stop_sort_key] [max_count]
- - scan_all [max_count]
- - copy_data <target_cluster_config_path> <target_table_name> [read_uncompress_type(none|zstd)] [write_compress_type(none|zstd)] [max_count]
-
- For example:
- PegasusCli file://./pegasus.properties temp get hash_key sort_key
- PegasusCli file://./pegasus.properties temp scan hash_key '' '' 100
-```
