I attended Berlin Buzzwords 2010 for the last two days and aside from meeting a bunch of great people during talks, here are some take away notes from this conference:
I got introduced to new stuff — such as HyperTable (c++ bigtable implementation), which I had never heard of before.
I actually know a lot more about hadoop, HDFS and tika now than I did before — though I won't be able to use
anya lot of it soon. The HDFS talk in particular was interesting as it got rid off the bells and whistles (OMG distributed file system and replicated!!!) for me. On Hadoop — it was easy to feel a little overwhelmed.
No MongoDB for me.
Hilarious: "Localhost is local most." (by Mario Scheliga)
(On HDFS' issues with the NameNode:) "Highly available vs. pretty highly available."
A lot of people talked about scaling (in and off talks) without a) having any first hand experience and/or b) a need for it. That was probably the buzzwordy part about this conference.
I did not learn as much about Lucene as I wanted or had planned. Primarily because the nature of the talks was a little too advanced for me. A basic introduction to Lucene/Solr's architecture and ways to scale out is still on my wish list.
I noticed that contributors to Apache projects like to discuss Jira issues in their talks.
Twitter is using Lucene/Java to scale out its (near real-time) search, but sticks to trivial types (instead of objects) to (re)gain performance.
Riak seems pretty cool: consistent hashing, auto-balancing, sharding — must investigate more. Also, Rusty Klophaus is a cool guy and I learned that Basho is not just a software company, but they also have a band. And riak is Indonesian and stands for something like how the water flows.
Cassandra looks interesting as well. Considering they are
Javanot written in Erlang, a lot of people seem to like them anyways. Also, Eric Evans is a great presenter — kudos to him. I especially liked the part where he suggested to not use Cassandra for obvious reasons, but the inner geek disagreed.
I don't know why presentations by Nokia, are like that. I'm missing a little enthusiasm about work or project.
Bashing other projects sucks. Also, introducing yourself with, "We are like X but better.", makes you look shady as well.
Benchmarks on slides really suck. And if people still can't resist, they should have a better explanation for them.
Berlin Buzzwords really had a great venue.
Thanks mucho to the organizers — Isabel, Simon, Jan & newthinking — for an interesting conference.
