Thanks for your comment Michael.

Actually, I think partiQL will work quite well for single table patterns mainly because the WHERE is mapped to a partition key (whether its a primary partition key or a global secondary index). I don't know how complex your queries are normally, but for example, if I have a table I can easily write a simple query as follows:

SELECT * FROM "myTable"."mySecondaryIndex" WHERE "myParitionKey"='sth sth' and "mySortKey" = 'sth else'

Enter fullscreen mode Exit fullscreen mode

In fact, it is the multi-table design that is not easy to implement in a single query bcz I don't think PartiQL implementation in dynamodb supports sub-queries at the moment, however, multi-table operations can be faciliated using dynamodb transactions.

In terms of performance, PartiQL performance is the same as current dynamoDB methods. There was a twitch session (DynamoDB office hours by Rick Houlihan) that was done around the 10th of December 2020, where Rick actually compared the performance of partiQL and dynamoDB API on a java app and he was running thousands of batch records, and the performance was the same.

I wanted to link to that twitch session but it seems it's currently archived, I already pinged Rick last week to see if they can put it back online.
