What is the actual difference between dissect filter and dissect processor and they both seem to have same functionality and different syntax.

Syntax for **dissect filter plugin**.  
filter {  
dissect {  
mapping =\> {  
"message" =\> "%{ts} %{+ts} %{+ts} %{src} %{} %{prog}[%{pid}]: %{msg}"  
}  
}  
}

Syntax for **Dissect processor**.  
{  
"dissect": {  
"field": "message",  
"pattern" : "%{clientip} %{ident} %{auth} [%{@timestamp}] "%{verb} %{request} HTTP/%{httpversion}" %{status} %{size}"  
}  
}

A dissect filter runs in logstash. A dissect processor runs in elasticsearch. They can be used to do much the same thing.
