No, it is within the individual json object storage. In a way, it would be
part of query plan,
but strictly for the individual json object storage structure, it is not
necessarily an "index"
one possible(but primitive) implementation could be like having multiple
"segments" in the storage,
all keys

Hello:
I'd like to bring this JSONB performance issue again.
Below is a link of MySQL way of storing/retrieving Json key/value
https://dev.mysql.com/doc/refman/5.7/en/json.html
Instead of providing column indexing(like GIN for JSONB in Postgresql).
it provides only internal data structure level

Using JSON/JSONB type in postgresql is usually due to the use case that the
keys (top level included) can not be predefined. this is the major
difference between NoSQL/Document and RDBMS.
Why would TOAST have to be used? Can some speciailly structured "raw"
files be used

Is there any database that actually supports what the original poster
wanted ?
The only thing that I know that's similar is bigtable/hbase/hypertable wide
column store.
The way it works is:
break the lexicographically sorted rows into blocks of compressed XXKB, and
then keeps an index on the start

Hi,
Congrats on the official release of 9.5
And I'd like bring up the issue again about if 9.6 would address the jsonb
performance issue
with large number of top level keys.
It is true that it does not have to use JSON format. it is about
serialization and fast retrieval
of dynamic tree structure

It is actually a very common use case of exporting data of several user

Unfortunately, the keys can not be predefined or fixed. it is a doc, the
reason jsonb
is used. It works well for small docs with small number of keys.
but really slow with large number of keys. If this issue is resolved, I
think Postgresql
would be an absolutely superior choice over MongoDB.for do
Hi, Thanks for everyone's response.
The issue is not just compression, but lack of "indexing" or "segmentation"
when a
single doc has, say 2000 top level keys (with multiple levels of subkeys).
right now, if I query for one key, the whole doc
has to be first uncompressed and loaded and then sear
