Very useful video Alex. Thank you. Can there be more than one sort key in the composite primary key? For example if partition key is customerId#, could there be 4 other sort keys such as customerAddress# [along with attributes], customerDemographicInfo#[along with attributes], customerAdditionalInfo#[attributes], etc? I am trying to create a one to many relationship for unique customers in my table to their many addresses, contacts, etc.

@alexbdebrie 2 года назад

Thanks, Bahar! For your question, will these each be different items in your table? If so, the answer is yes -- you can have different items with different sort key patterns. Let me know if I'm misunderstanding -- feel free to email me or DM me on twitter.

Does aws keyspace let you know how much clusters is being running for that table? 4:33

@alexbdebrie 3 года назад

Nope, this is all hidden from you. You can sneakily find out the number of partitions in your DynamoDB table by examining DynamoDB streams, but it shouldn't really help you much. Project to find number of partitions here: github.com/zaccharles/dynamodb-table-partitions

@RahulAhire 3 года назад

@@alexbdebrie no, I'm actually talking about aws Apache keyspace - 4:33 Is it visible.

@alexbdebrie 3 года назад

@@RahulAhire Ahh gotcha. No, I don't think so.

Hey in ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ErPrf74RUDY.html you say "remove partitions". Does DynamoDB actually remove partitions?

@alexbdebrie 3 года назад

Good catch! They don't really tell us (we don't need to know!), but I believe DynamoDB doesn't actually remove partitions after they're created. That said, because we don't need to know, they could change that in the future if needed.
