It looks like the conjars.org Maven repo was shutdown by its owners. If you are having build failures, DM @cwensel for options to get back up.

Do you miss meetups of the Big Data era, when you could learn about RAFT protocol or map-side join over pizza and beer? Us too! My friend @cwensel has launched SF Distributed Systems Meetup. First meetup is next week, with talks by me and @conor_power23 lu.ma/t6r4mi4v

If your company is still running Cascading+HadoopMR applications and are itching to drop MR for Spark, dm me. Some companies have 100s of @Cascading apps in production and moving them off MR in a couple lines of code would be a huge cost savings. Also true for @scalding.

I always suspected that Parquet and Orc weren't very good, but TIL from @ViktorLeis that one can do much much better with BtrBlocks. cs.cit.tum.de/fileadmin/w00c…

Before I worked at Hortonworks putting Calcite in Hive, I worked on Lingual, a SQL interface to @cascading. That was the first commercial use of Calcite (then called Optiq) and some much needed consulting $$

I'm hanging my shingle out again. I have some new insights I want time to work out into a developer tool for cloud data engineers, but I want to bootstrap it with contract/consulting revenue. This is how I started @Cascading in 2007. chris.wensel.net Please boost!

Scala folks: if there are open source GitHub Twitter libraries you like, you might want to make a clone/fork now. Seems like we are in a situation where anything can happen. – at Paia, HI

really interested in adding mergeable summary as a datatype to @cascading. think having daily/hourly aggregate tables, then daily/hourly performing a last N day/hour aggregation against the partials. cost efficient way to have rolling percentiles/aggregates

cross your fingers, we might have a @cascading 4.1 release tonight, and a quick 4.5 release a day later w/ Hadoop 3 support. Both will include native @ApacheParquet support to replace the support dropped by Parquet. Plus some well worn enhanced Parquet support in 4.6

For fun I really want to fork the @cascading local mode planner to support RocksDB as the backend for joins instead of the memory only hashmaps. Local mode was never intended to scale in joins.

Google gs connector does do aligned block reads...both that and this one work well for backwards seeks (footers, stripe footers -> stripes) /2
