kafka 获取topic每个分区的数据条数

执行命令

[hduser@hadoop4 bin]$ kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list 192.168.43.15:9092 --topic test  --time -1
test:0:992786

[hduser@hadoop4 bin]$ kafka-run-class.sh kafka.tools.GetOffsetShell 
An interactive shell for getting topic offsets.
Option                                 Description                            
------                                 -----------                            
--broker-list <String: hostname:       REQUIRED: The list of hostname and     
  port,...,hostname:port>                port of the server to connect to.    
--max-wait-ms <Integer: ms>            DEPRECATED AND IGNORED: The max amount 
                                         of time each fetch request waits.    
                                         (default: 1000)                      
--offsets <Integer: count>             DEPRECATED AND IGNORED: number of      
                                         offsets returned (default: 1)        
--partitions <String: partition ids>   comma separated list of partition ids. 
                                         If not specified, it will find       
                                         offsets for all partitions (default: 
                                         )                                    
--time <Long: timestamp/-1(latest)/-2  timestamp of the offsets before that.  
  (earliest)>                            [Note: No offset is returned, if the 
                                         timestamp greater than recently      
                                         commited record timestamp is given.] 
                                         (default: -1)                        
--topic <String: topic>                REQUIRED: The topic to get offset from.

2、获取条数

从上述的命令解析可以看到，
--time -1 表示获取的最新位移值
--time -2 表示获取的最早的位移值，可能由于最早的数据由于过期被删除，所以最早的位移不一定是0
通过两数相减，就可以知道当前分区的数据条数。
