Consider a persistent class of MyObjects with a bitmap index on Property1, and then have a subclass of MySpecialObjects.

If I use

select * from MySpecialObjects where Property1 = 'Something'


I only want the items that are MySpecialObjects and not any other MyObjects. The extent index makes this possible. It ANDs the MySpecialObjects extent index with the Property1 index.

A bonus, is it also makes select count(*) very fast, even with tables of over 50,000,000,000 rows

Look into using Interoperability. The classes EnsLib.REST.Operation and EnsLib.HTTP.GenericOperation should do what you are looking for depending on if you are calling a REST service or it is plain HTTP

We have several business operations that use EnsLib.REST.Operation, each with pool sizes of between 2 and 60. Providing the http response indicates the connection can be maintained, they will keep the connection open.
