Repo is down - 502 Bad Gateway error

[gcaplan]

Running ObjectBoxInstallScript.ps1 on Windows 10 Pro is failing.

Attempting to access https://dl.bintray.com/objectbox/conan/objectbox/objectbox-c returns a 502 Bad Gateway error.

Looks like a great project and I'm keen to get ObjectBox up and running for an urgent evaluation. Please advise on how I can get my hands on the .dll as I can't spot it on the open web.

While I'm in contact, my requirement is to select a subset of objects sorted by integer key from a set of some millions in a flat table.

It's not clear from a quick scan of the docs how ObjectBox handles sorting internally.

SQLite has a sorted index, and I'm getting reasonable results.

To be sure it's worth the effort of setting up a test, is there a reasonable chance that ObjectBox would give me equal or better performance on these large sorted selects? The insertions will not be made in index sequence.

All being equal, I'd prefer ObjectBox to SQLite because of the faster ingestion provided the select queries would at least match the SQLite performance.

Thanks for reporting. ~But where is this ObjectBoxInstallScript.ps1 script from?~

The Powershell install script from this repo appears to download from the correct URL. See also https://golang.objectbox.io/install#windows Edit: the script linked from the docs page was outdated.

As for selecting/querying see https://golang.objectbox.io/queries

At the cost of storage a query on a specific property can be sped up by indexing it.

Thanks - the script you sent me has run correctly.

From memory, the install script that failed was downloaded off a link in the getting started docs for the Go driver, but I may be wrong. I've included the code below.

You may want to track this down and get it fixed...

Hi Uwe

I've hit another issue. I'm not a C developer so I'm not clear if this is a bug or simply that I'm misunderstanding something.

I've posted the details here:

https://github.com/objectbox/objectbox-go/issues/39

Please take a look as soon as convenient.

Geoff
