As per the discussion with other team members they suggested if we store 50
values for keys in an individual column that will provide better
performance as the data type is native (INT2) on the other hand if we store
all the key value pair in a single JSONB column the performance will
degrade even after applying a GIN index on that however the statement
sounds funny but I want to take everyone openion?

This is unclear, I am trying to figure out you go from &#39;50 key value <b=

<br>
In other words how 50 pairs turn into 50 columns?<br>

Then there is the question of why 50 keys per row in the first place?<br>
