QUESTION
Take the following Entity Framework Core entity class:
...ANSWER
Answered 2021-May-22 at 15:47After a significant amount of further experimentation, I discovered that the error message in my original question was ultimately a red herring and that using the UlidToBytesConverter
inheriting from ValueConverter
was all that was required!
The problem appears to have been caused by the fact that using a custom type as primary and foreign keys breaks EF Core's convention-based mapping of foreign key properties (e.g. automatically mapping CompanyId
to the Company
navigation property). I can't find any documentation describing this behavior.
Accordingly, EF Core was trying to create a new property CompanyId1
and for some reason the value converter was not being applied.
The solution was to add the ForeignKey
attribute as to the CompanyId
property as follows:

As you may have already seen it's evident you are hitting more than the 1GB configured. The answer probably lies in how you are using Prometheus and what usage limits you are hitting for 1GB. Some of the things you can look at:
- Number of Time Series
- Average Labels Per Time Series
- Number of Unique Label Pairs
- Scrape Interval (s)
- Bytes per Sample
You can find a memory calculator for the usage above 👉 here.

QUESTION
I used this ULID example in a project where I not only needed the uniqueness offered by ULID but also its lexicographic sortability.
I discovered, however, that no matter how much I tried, I could not just get the ids generated in a loop sorted.
e.g.
...ANSWER
Answered 2020-Jul-22 at 11:38The ULID has two parts: a time component and a random component.
The time component is the count of milliseconds since 1970.
The random component is updated in two cases:
- when the millisecond changes, a new random value is generated;
- when the millisecond is the same, the random value is incremented by one.
The implementation you show here doesn't do the second step.
Maybe you could include some code like this (just an example):
QUESTION
I am using the Prometheus for past 15 days. from yesterday the service is failing because of out of memory.
I have increased the memory from 4GB to 8GB but now I am unable to start the Prometheus service and failing with below error :
...ANSWER
Answered 2020-Mar-22 at 01:34Are you running 32-bit prometheus? You're probably running out of address space. I don't think Prometheus plans to make this work on 32-bit systems, it simply runs out of 4GB address space with all the mmap
ing happening.
