java - Bidirectional messaging system using kafka -


is there possible develop bi-directional messaging system using apache kafka ? need subscribe topic consumer need send message consumer.

you 1 of 2 ways. either set prefix system message keys or put content inside of message allows consumer avoid messages has produced.

now whether should design this, depends on message traffic. if you're not slamming events, might better consider thrift way have message components bidirectional communication. kafka excels relative complexity when need produce , consume massive volumes of data. might not case you.

for example, 1 common use case kafka hook service storm, apex or samza doing distributed processing of hundreds of gb or tb of data. if system has high throughput requirement, architecture 1 consider starting point kafka handling messages. storm, if need send messages reprocessing, can use kafka bolt republish message kafka ensure gets reprocessed.

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
