Hadapt is moving forward

I’ve talked with my clients at Hadapt a couple of times recently. News highlights include:

The Hadapt product story hasn’t changed significantly from what it was before. Specific points I can add include:  

A very busy Daniel Abadi also took the time to walk me through how Hadapt does joins. More precisely, what we discussed about joins includes some of the last features being added to Hadapt 1.0; many of the pieces are still missing from early-access Hadapt 1.0, and some may even slip out of the Hadapt 1.0 GA version. As Dan tells it, there are five kinds of joins in Hadapt:

Highlight’s of Hadapt’s performance story include:

    Interesting article on Hadapt.

    Although reading about the 5 types of joins you explained, for me it drew uncanny parallels to the join mechanisms on Teradata mainly the Merge and Hash joins.

    -> Co-partitioned join is akin to TD’s Merge join on PI=PI
    -> Directed join is akin to TD’s Merge join on PI = Non-indexed column where it resdistributes the 2nd table based on join key
    -> Broadcast join is akin to the merge join where the smaller table gets duplicated across all amps.
    -> Split semijoin/Distributed/parallel hash join sound familiar to hash join and hash joins on the fly.

    Add MapReduce on top of TD DBMS and voila – what am i missing?

    I don’t think Hadapt claims to have invented much in the way of fundamentally revolutionary database algorithms.

    Rather, they’re trying to take what they regard as the best of database theory (more precisely some of the best), apply it in a somewhat new way, and solve whatever engineering challenges then ensue.
