[Minio] About dynamic blob storage container naming #741

Hi,

I want to create buckets dynamically at runtime (and named blob containers also) depends on incoming data (for example I want to store data with daily bucket names. If a record is created on 29-12-2020, my bucket name should be bucket-29-12-2020). But Abp supports blob container configuration while configuring services at startup. How can I achieve this functionality ?

Thanks for your help.

    Hi,

    You can customize the implementation of IBlobNamingNormalizer:

    [Dependency(ReplaceServices = true)]
    [ExposeServices(typeof(IBlobNamingNormalizer))]
    public class MyMinioBlobNamingNormalizer : MinioBlobNamingNormalizer
    {
        public override string NormalizeContainerName(string containerName)
        {
            containerName = base.NormalizeContainerName(containerName);
    
            return containerName.Replace("{date}", DateTime.Now.ToShortDateString());
        }
    }
    

    Your container:

    [BlobContainerName("bucket-{date}")]
    public class DayRollingContainer
    {
    
    }

    Thanks for your attention.

    @liangshiwei, your approach should work but there is one missing point for my case. Date parameter may not be today. I need to set it explicitly at runtime.

    Hi,

    You can change it according to your needs, for example, read a date from the settings.

    Hi,

    I do not need to set it from a setting or a constant value. I want to set it according to a property of an entity. It is dynamic and changes on every user request to the application service. For example;

    SaveBlob(1) -> Find record with id -> Read creation date -> 2020-01-05 -> Save blob to bucket "bucket-2020-01-05" SaveBlob(35) -> Find record with id -> Read creation date -> 2010-11-22 -> Save blob to bucket "bucket-2010-11-22"

    Hi,

    I've achieved this by overriding MinioBlobNameCalculator, MinioBlobProvider and BlobContainerFactory. It should not be that hard. I think abp should support this functionality with an easy way.

    Also, I think GetContainerName function of MinioBlobProvider has a bug. Configuration does not allow empty or null bucket names but that function checks for that and never uses true condition of comparison.

    // always false because empty or null values are not allowed, application throws exception while starting up return configuration.BucketName.IsNullOrWhiteSpace() ? args.ContainerName : configuration.BucketName;
