Re: Now where can you use my ParallelSort library ?

Hello,

If you don't want to use a binary search in my previous exemple e, don't use 
it.

But in the following SQL select:

select name
from titles
where (type = 'business' or type = 'psychology')


It is better to use a binary search after you have sorted the array
with parallel sort library.

Here you can construct the titles table with Parallel hashlist(of course you 
can add
more than one table to parallel hashlist)  by copying, for exemple, the data 
from a database to the parallel hashlist's table, and after that copy this 
table to an array and after that sort the array in parallel on the type key 
with my parallel sort library ,
and after that use a binary search function to find the type that
equal 'business' or equal 'psychology' etc.

This is how you can use Parallel Sort library and Parallel Hashlist as 
in-memory database,
and of course you have to use TCP/IP to be able to use Parallel Hahslist as 
an in-memory database
server.
