First, #ApacheParquet removed #Cascading support, so I had to splice the original source into Cascading. But the ParquetScheme didn't honor type information fully. So there is a new TypedParquetScheme that has native support for JSON and Timestamps.

Second, Parquet requires the #ApacheHadoop FileSystem, which means we get the wonderful S3A implementation. But we also get a 331MB jar dependency with the aws bundle.

FosstodonChris Wensel (@cwensel@fosstodon.org)Hey #data engineers, I've started a new project called Tessellate. It's for reformatting and partitioning data from/to text, csv/tsv, json, and @ApacheParquet locally or AWS. https://github.com/ClusterlessHQ/tessellate Repartitioning datasets is it's primary focus so you can leverage push down predicates in #AWS Athena, prestodb, trinodb, etc.

A new tool developed by #European and #Australian scientists shows that #cascading extinctions of interconnected #species are unavoidable due to #climatechange. The Earth is expected to lose 10% of its #animals and #plants by 2050, rising to 27% by 2100.

This is especially concerning as we continue to see the effects of climate change on our planet. It highlights the urgent need to address climate change and protect #biodiversity.

Hello Mastodon, or is it Tootland? I'm so confused...I will just blunder on, confused as usual!

I'm Heidi Stenner, a #hazards geologist and Project Manager with #GeoHazards International (#GHI) a non-profit focused on working with lower-resourced global communities who are at high risk of natural hazards and climate change impacts.

I have been an #earthquake #geologist and #paleoseismologist with USGS. Migrated into #scicomm #disasterprep. I'm most interested in #EQ #landslide #volcano #compound #concurrent #cascading #disasters and how to #mitigate #adapt #plan to reduce their impacts.
