<div dir="ltr">You can do it as per my knowledge. Only thing is you will access in drl from java code. I dont think it will be an issue. but what the reason for sending hashmap as fact, You should have a different way of sending facts. As per my observation no rule needs so much of data to make a decision. It should have name value parameters to make the decision. <div>

Hi,
<br><br>Is it possible to insert redis hashmap as it is as fact into rule engine. I am using Jedis from java to access jedis and drool rule engine.
<br>Also, Is there a way to access redis hashmap from drl file.
<br><br>Thanks,
