postgresql - Difference between JSON and JSONB in Postgres -


this question has answer here:

what's difference between json , jsonb data type in posgressql?

  1. when should used specific one?
  2. what's benefits or disadvantages respect other?

this explain: https://www.citusdata.com/blog/2016/07/14/choosing-nosql-hstore-json-jsonb/

in cases jsonb want when looking nosql, schema-less, datatype. hstore , json can have place it’s less common. more broadly, jsonb isn’t fit in every data model. can normalize there benefits, if have schema has large number of optional columns (such event data) or schema differs based on tenant id jsonb can great fit. in general want:

jsonb - in cases json - if you’re processing logs, don’t need query, , use more of audit trail hstore - can work fine text based key-value looks, in general jsonb can still work great here

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
