hi @APentyala    1. 1. Data Modeling Design: Which model is best suited for a Lakehouse implementation, star schema or snowflake schema? Ans: We don't have those designs or we are not aware of those 2. We are using CDP (Private) and need to implement updates and deletes (SCD Type 1 & 2). Are there any limitations with Hive external tables? Ans: There are no limitations for EXTERNAL tables. Are you using HDFS or islon to store? 3. Are there any pre-built dimension models or ER models available for reference? apentyala   Ans : We don't have any thing as such     ... View more

@APentyala  Please find the answers below:   1. Which data modeling approach is recommended for this domain? Ans: If you have large data, we would recommend to go with Partitioning or multi-level partitioning. You could implement Bucketing if the data inside partition is large. 2. Are there any sample models available for reference? Ans: You could take a refrence for partitioning and bucketing in https://www.linkedin.com/pulse/what-partitioning-vs-bucketing-apache-hive-shrivastava/ You could create a new table perfroom CTAS with Dynamic Partitiining from the existing table Refrence: https://www.geeksforgeeks.org/overview-of-dynamic-partition-in-hive/ 3. What best practices should we follow to ensure data integrity and performance? Ans: Please follow below best parctices: a. Paartion and bucket it b. You could use Iceberg table which would reduce the significant load on Metastore, if you are using CDP Public CLoud or CDP private CLoud(ECS/Opesnshit) c. Use ORC/parquet d. Use EXTERNAL tables,if you dont perfrom Update/Delete as reading External table is faster. 4. How can we efficiently manage large-scale data ingestion and processing? Ans: The model follows as: Kafka/Spark Streaming: Ingestion Spark: Data Modelling Hive: Warehosuing where you extract the data Please. be specific on the use case. 5. Are there any specific challenges or pitfalls we should be aware of when implementing a lakehouse in this sector? Ans: There should be no challenges, we would request to provide more briefing on this. ... View more

@Maicat You can not typecast array to the string. There are 2 ways you can use  1. Select the nth object of the array.     SELECT level5[0] AS first_genre FROM my_table;     WHere 0 is the first object 2. You can flatten it SELECT column1 FROM my_table LATERAL VIEW explode(level5) genre_table AS level5;          ... View more

To use an internal load balancer for Cloudera Data Warehouse (CDW), you must select the option to enable an internal load balancer while activating the Azure environment from the CDW UI. Otherwise, CDW uses the Standard public load balancer that is enabled by default when you provision an AKS cluster.   Before activating you should remove.https://docs.cloudera.com/data-warehouse/cloud/azure-environments/topics/dw-azure-enable-internal-aks-lb.html ...
