  26. 26. 26 Implementation Case Study • Hospitality industry analytics – Detailed transactional data – Weekly / monthly / yearly trend analysis – Began with single-node cluster, adding nodes as data volumes grow Source Data Redshift Analytics ETL
  27. 27. 27 • Collect external data loads before merging with existing data • Maintain history of cleansed and standardized source data • Use data structures optimized for analytics – Dimension and fact tables for analytics – Aggregate tables Best Practice #1: Choose The Right Pattern • Staging tables • History tables • Star schema data warehouse Requirements Design
  28. 28. 28 Best Practice #2: Select the Right Node Type • Performance was good with initial volumes and small data sets on single node • Evaluated dense storage (dw1) and dense compute (dw2) nodes • More opportunity to optimize design as volumes grew • Increased nodes to handle larger volumes – Solution leverages dense storage (dw1) nodes – Expected to stabilize between 10-20TB • Have also seen smaller volumes that work really well in dense compute (dw2) nodes Early Stages Mature Stage
  29. 29. 29 Best Practice #3: Leverage MPP • Spread data evenly across nodes while also optimizing join performance • Distribution key and sort keys are primary considerations Leader Node Compute Node 1 Compute Node 2 Compute Node n Compute Node 3 • Initial fact table distribution key caused skewed data • Changed to dimension foreign key with better distribution for 40%+ improvement in query times • Surrogate keys on dimension tables – Primary key – Sort key and distribution key OR distribute to all nodes – Sort on foreign keys in fact tables Goals Approach
  30. 30. 30 Best Practice #4: Use Columnar Compression • Started with compression settings based on general data types – VARCHAR to TEXT255, INTEGER to MOSTLY16, etc. – Iterate using ANALYZE COMPRESSION • Redshift applies automatic compression during COPY – Staging tables • Reduce I/O workload by minimizing size of data stored on disk Goals Approach
  31. 31. 31 Best Practice #5: Load and Manage Data • ETL and ELT – ETL: First set of processes prepares data for analytics – business logic, standardization, validation – ELT: Second set of processes load data into Redshift and transform into analytical structures • Data management – Enforce constraints within ETL processes – Analyze after loads to update statistics – Vacuum after large loads to existing tables, updates and deletes
  32. 32. 32 Bringing it All Together • Analytic queries – Minimize number of query columns to improve performance – Most queries use SUM or COUNT – Leveraging aggregate tables for monthly dashboards • Explain long running queries to help optimize design – Sorting / merging within nodes and merging at leader node
