Sure. Glad that it can help! The slides are in WIP state and I'll add more in the next meeting: https://docs.google.com/presentation/d/1uj8m7y69o47MhpqCc0SJ03GDTtPDrg4m04eAFVmq34A
In the meeting, we also talked about pain points from Hulu: - We're still using Hadoop2 (CDH5) so can't upgrade to Impala 3.x. Hulu is a customer of Cloudera but we're not using Impala-cdh5.16 since it's lack of ORC support and maybe other features not picked up to cdh5.16. - Metadata issues: - (a) Poor performance on huge tables (with many partitions) - (b) Need to invalidate/refresh metadata in existing pipelines - Graceful shutdown - Support for RDBMS like MySQL/SQLServer/PostgreSQL Hopes to solve the metadata issues by cherry-picking patches from the master branch to branch 2.x. We're still looking forward to a solution for supporting for RDBMS (IMPALA-8210). Hulu is also interested in Impala's Roadmap or what topics Cloudera folks are focus on. JIRAs are too detailed to get a whole picture. Hopes we can have a webpage or GoogleDoc for this.
