Anyway the Memcached Input/Output plugins allow for the reading and writing of key/value pairs to memcached instances. The Input step requires incoming key names, and the type of the values that will come out:
The Output step requires and value field names (it interrogates the types from the row metadata):
This is just an initial offering, eventually I'd like to add other features (I'm always open to suggestions for improvement!). But I figured I should get a foot in the door for key/value store support :) I also have been working on a Map (key/value) type for PDI, that should be out in 5.1 or before if I can get some supporting changes into the 5.0.x code line.
Please feel free to install this from the PDI Marketplace and let me know how it works for you and/or how it could improve :) I only tested this on PDI 5.0, so I'm not sure it will work on PDI 4.x but I don't see any reason it shouldn't.
