[GENERAL] Jsonb extraction very slow

[hari.prasath]

Hi all

     I am using jsonb for storing key-value pair information(500 keys) and it 
was a very big data set with some 10M rows. Whenever i try to extract some 
keys(let say some 10 keys and its values) its really very slow.



Is this due to jsonb parsing (or) each time json will be loaded from disk to 
memory for 10keys(mainly if my keys are at end of 500 this is very slow).?






cheers
