A good interview on InfoQ comparing Hadoop with AddThis’s open source Hydra:
What use case(s) is Hydra better suited for compared to Hadoop. When would Hadoop be a better choice?
Hydra is better at data exploration. You can follow a number of interesting leads from the results of a single, probably rather fast, map job. Queries on the resultant tree usually take on the order of seconds (or milliseconds).
Non-programmers can produce functioning products with a small amount of guidance. The web UI provides most everything that might be needed; it might be as simple as pressing clone on an existing job, changing the tree to use a couple different features and hitting go. In minutes they have a new URL endpoint to show your impressive new KPI on your company home page.
Hadoop has a few advantages though. It has stronger native support for very large, one-off joins. Technically speaking this just means more implicit sorting of files. Sorting huge numbers of things is expensive so we try pretty hard to avoid it, and as a result first order support for it is a little lacking. On the other hand, you might find that you don’t really need the full, perfect join and are instead content with a Bloom-filter-based probabilistic hybrid — in which case Hydra will once again save you some sweet cycles.
Last week I wrote this piece for Comic Book Resources about the new Teen Titans #1 cover. The point of the piece was hey, there’s a broad demographic DC *could* be hitting with this book but the cover is certainly not made for that potential demographic. Instead, it’s more of the same-old,…
Let’s all come out and say this behavior is not acceptable to our community. The tech community sees this too - and it’s not acceptable there either. Or anywhere.
Q:Are there any plans to upload Powers and Alias onto Marvel Unlimited? Thanks.
Powers is a creator owned comic and not a Marvel comic. alias has content issues that do not match the general audience rating for the Marvel Unlimited or marvel app
I had a lengthy talk with Marvel about this this week. with the Jessica Jones TV show looming you will find a digital version available somewhere somehow
also very good news for the 4 million people who have asked the alias omnibus hardcover is going back into print in July and there will be a pulse collection as well.
Pre-ordering alias omnibus now…
