What are the main differences between local and global indexes in Apache Phoenix?
When is it good to use one and when the other?
I tried googling but I don't find anything on that topic.
Also, I know how to list all indexes but is there a way
to tell which ones are global and which ones local?
My guess is this:
When I run this SQL query local indexes will give me cnt=2 while global will give me cnt=1.
select table_name , count (*) as cnt
from
system.catalog where table_type = 'i'
group by TABLE_NAME
order by count(*) desc;
Is that a good criterion to distinguish between local and global indexes?
