Very well done presentation! Informative with no filler.

DynamoDB is an example that not all No-SQL databases are designed equal. DynamoBD is very strict in the design of access patterns, if you need to perform a query with a query method and you don't have the necessary index (and if it is composite you must concatenate it in a column) it will be difficult for you to access it efficiently, it requires more careful planning than other DBs

[@lmb_codes]

TBH, responsible engineers should apply thoughtful planning - even with traditional relational DBs, especially with indexes for access patterns. it would be really embarrassing to experience slowdowns in prod just because someone forgot about an index and executed a full table scan 🤣

[@jasonhunter1786]

Right, DynamoDB aims to be fast and efficient. You can't push unbounded work onto the database. You must consider your update and access patterns as part of the schema design.

[@michaelpotter1775]

Good Observation: i see this as an upside. Others will see it as a downside and probably just us a different tech.

[@kronostitan11]

Excellent video

[@wiktormigaszewski8684]

thnx, this was actually interesting

[@harikrishnarenumanu6829]

how we will decide which database we should choose to an work

[@awssupport]

Great question, Harikrishna. 🧐 See this guide on choosing the right database to start with: go.aws/46Dnf95. You can find information on the different types of databases and available services on AWS. You may also find this best practices guide for databases helpful: go.aws/3tF6TOM. ✅ ^MO
