Support for Directory in Azure Blob storage?

[Manfred Lange <ma...@gmail.com>]

Hi,

Just wondering if there is any support planned for a directory that is
stored in (or backed by) Azure Blob storage.

I'm aware of the project AzureDirectory at
https://github.com/azure-contrib/AzureDirectory

However, that project hasn't been updated in quite a while yet probably
because the latest .NET release for Lucene.NET is 3.0.3.

I'm after support for the target `netstandard2.0` which appears to be
included in Lucene.NET version 4.8. However that is only available as a
beta at the moment.

AzureDirectory doesn't appear to move unless Lucene.NET 4.8 has been
released.

So, here hare my questions:
1. What is the plan for the release date of Lucene.NET 4.8?
2. Are there any plans to support Azure Blob storage as a directory?

Thank you!

Cheers,
Manfred.

Hi Laimonas,

thank you for your note, very much appreciated!

The lack of progress for Lucene.NET is a bit of a shame, I think, as Lucene
as such is extremely useful. Over the last few years we have used it in
various .NET projects and never had a major issue.

It sounds as if Lucene.NET is dead on .NET and at best there is activity on
the Java side of things. One option certainly would be to use a container
with the original Lucene inside. Another alternative would be to use one of
the search offerings by the large cloud providers, e.g. Azure Search. I'll
have to check that.

Since I wrote my email we've implemented a new AzureDirectory for
Lucene.NET that targets `netstandard2.0`. It is based on Lucene.NET 4.8
Beta 5 and by and large it seems to work. I'd be happy to contribute this
code if that would be of any help. It is based in part on the existing
AzureDirectory which hasn't moved in the last few years either and targets
.NET 4.5 only but not netstandard2.0. I have contacted the maintainer/owner
of the exsiting/old AzureDirectory as well but haven't heard back yet. An
additional complication for the implementation was the mess Microsoft
created over the last couple of months around the client .NET library for
accessing Azure Blob Storage and moving that client library to
netstandard2.0 as well. This time Microsoft really screwed it up.

If you know of other alternatives for full-text search on .NET apart from
Lucene.NET or if you are interested in our new netstandard2.0
implementation of AzureDirectory, please let me know. Thank you!

Cheers,
Manfred.

Manfred,

The development has stalled at the moment. We had a very sporadic committer
activity in the last couple of years and it's been silent for a while. Not
sure if at this point Lucene.NET 4.8 will leave the beta stage.
