DistributedMapCacheServer

["Saxena, Shishir" <Sh...@csx.com>]

Hi,
  I have a use case where I am looking to store only one attribute from my flowfile to DistributedMapCacheServer. My flowfile is potentially large so I am not looking to push complete flowfile to DistributedMapCacheServer.  At a quick glance, it looks like I can store complete flowfile using PutDistributedMapCache and retrieve complete flowfile using FetchDistributedMapCache. Can I only store specific attribute ?

Is there a way to do it ?

Thanks for everyone's help.

Hello,

Not totally sure if this will work for every case, but at some point in your flow you could split off and send a flow file to ReplaceText, and set the Replacement Value to ${your.attribute} to overwrite the content of that flow file with your attribute value, from there send to PutDistributedMapCache.

Would that work for your scenario?

Thanks,

Bryan
