Sir, I just want to say thank you so much, I've gone through many videos but was still confused, u made this crystal clear with all your conceptual approach.
Thank you for kind words. I'm so glad my videos are helping you. That's why I do them. I know this technology is not easy to learn so kudos to you for sticking with it.
Can we implement data lakehouse with open source tools like spark, presto & hive metastore ? is there any alternative for unity catalog in open source eco system
Lakehouse is just Delta Lake, i.e., delta tables which are available in open source Spark so yes. Unity Catalog is really just a catalog of catalogs so you could build your own central catalog by extracting the meta data from local Hive metastores. I believe Spark tends to work one cluster at a time unlike Databricks which spins any number of clusters up as needed so not sure if UC could be implemented on open source Spark but perhaps?
do you have an example in any of your videos connecting to an s3 bucket specifying an endpoint within databricks? basically how to connect to an s3 bucket from a service other than aws? Thanks
@@BryanCafferky yeah ha, i did find a solution eventually, i think somewhere from stack overflow, searched around several places so i don't have the exact source "sc
It's meant for data warehousing, i.e., warehouse = lake + house, so warehouse on a data lake. OLTP has stringent requirements like high data transactions concurrency, referential integrity, etc. Delta logging is done at a file level whereas SQL databases log at a row level. See my video on Delta logs to get an understanding of what I mean.
