Hi, New to memcached and am using is as a filter in logstash as follows;  
memcached {  
id=\>"getconditionterminology"  
hosts =\> ["${memcacheserver}"]  
namespace =\> "code\_concept"  
get =\> {  
"%{rsnstcode}" =\> "[mm\_rsnstcode]"  
"%{stsexpected}" =\> "[mm\_stsexpected]"  
"%{pbmtycode}" =\> "[mm\_pbmtycode]"  
"%{pmstycode}" =\> "[mm\_pmstycode]"  
"%{statuscode}" =\> "[mm\_statuscode]"  
"%{pondtcode}" =\> "[mm\_pondtcode]"  
}  
}

The problem is that if 2 of the variables have the same value e.g. pbmtycode and pmstycode have the same value (e.g. CC\_PRBCOMPLI) then the second returns a value of N/A rather than the value associated with the key - such as ....

[2020-07-17T11:30:00,945][INFO][logstash.filters.ruby][condition\_pipeline] pbmtycode: {"value"=\>"CC\_PRBCOMPLI"}  
[2020-07-17T11:30:00,945][INFO][logstash.filters.ruby][condition\_pipeline] mm\_pbmtycode: {"value"=\>"Complications"}  
[2020-07-17T11:30:00,945][INFO][logstash.filters.ruby][condition\_pipeline] pmstycode: {"value"=\>"CC\_PRBCOMPLI"}  
[2020-07-17T11:30:00,945][INFO][logstash.filters.ruby][condition\_pipeline] mm\_pmstycode: {"value"=\>"N/A"}

Why is this occuring and is there any setting so that if I ask for the same key twice I get the correct value each time? Thanks
