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
