kandi X-RAY | hank Summary
(DEPRECATED. This project is no longer used or maintained at LiveRamp.) Hank is a high performance distributed key-value NoSQL database that we built and use at LiveRamp. It is designed for very large data stores that dwarf the amount of available main memory and for randomly distributed read/write workloads that far exceed the capacity of memory-based caches. More specifically, it is optimized for very low latency random read queries and for very high throughput incremental batch writes.

Answered 2022-Mar-16 at 12:31As already mentioned by @_Takis it is a bad design to map each table from relational database to one collection. NoSQL databases like MongoDB are not optimized for joins, some NoSQL databases do not support joins at all!

Apologies if this is a super basic question, but I'm building a Radio Button component, which iterates over Array of Objects, each representing a User.
All the documentation and examples I see have hardcoded values, whereas my Array has constantly changing Users, what I want to know is, how I would adapt the below code to take the name of the Users as a value for each radio button.

QUESTION
I'm working on a factory; I need to eventually add custom methods, hanks to this answer and this answer, we was able to make it work almost as expected.
Almost because it works only with methods without any required arguments; if we try to add a method with at least one required arguments, we get a compile error.
I tried adding a rest argument array both to the declaration of method argument and M type (see below) but it helps only when calling the methods.
