Grok Patterns/Expressions for capturing comma separated key=value pairs in Nifi

[#1]

Hello all,

I am newbie in Grok Expressions and need some help with the same in Nifi.

I am trying to capture key=value pairs of log messages coming from Kafka using Grok Expressions in Nifi using the ExtractGrok Processor or the GrokReader Controller service. Eventually all the keys are the column names in a table and their corresponding values will be in fact the values of the same columns in the same table.

Here is how a sample message looks like.

Field1=value1, Field2 = value2,......................................................

Any help from anyone would be appreciated. Thanks
