Is there a plan for 9.6 to resolve the issue of very slow
query/retrieval of jsonb fields
when there are large number (maybe several thousands) of top level keys.
Currently, if I save a large json document with top level keys of
thousands and query/retrieve
field values, the whole document has to be first decompressed and
load to memory
before searching for the specific field key/value.
If it was my data, I'd be decomposing that large JSON thing into
multiple SQL records, and storing as much stuff as possible in named SQL
fields, using JSON in the database only for things that are too
ambiguous for SQL.
