Via [WayBack] Limits on Everything – The Isoblog.:
A posting at Brave New Geek about limits on everything, for example limits on message sizes and numbers of in-flight messages in message queues. Interesting read.
Very interesting read indeed: [WayBack] Take It to the Limit: Considerations for Building Reliable Systems – Brave New Geek
You have to set limits, which begs for a few questions:
- how to find out which limits and at what levels
- how to enforce these limits
Food for thought…
The first can be done with benchmarking, see for instance these from the same blogs above:
Enforcing limits depends in your infrastructure and your communication stacks.

A short while ago, I installed a pair of 1TB Intel 600p NVMe SSD devices.
Performing a straight rsync backup of some 100 gigabyte of data managed to shutdown both of them: the throttling was so much that VMware ESXi lost the volumes on it and showed “Permanently inaccessible device”.
I was quite surprised as the initial reviews did not mention any temperature problems, but apparently there are.
Since then I’ve put a 120mm fan near to it which made the problems go away, but it still every now and then jumped to over 60 degrees Celsius.
Later I “fixed” it in a better way for cooling getting the idle temperature around 30 degrees Celsius and heavy duty temperatures around 40 degrees Celsius:
I did not have to mount any M.2 heatsinks on them yet; they probably won’t fit under the fan anyway

Unlike for instance DropBox, Google Backup & Sync does not allow you do move the Google Drive location in a one-step way. You have to go through below ridiculous steps to move it around yourself.
A comment on G+ indicated I should try Insync. Not free, but way more stable and more features.

On my research list: Home – Outpan as it is a key-value store of EAN (actually GTIN, so including GS1 UPC, EAN which means barcodes like UPC-12, EAN-8, EAN-13 and ITF-14).
- [WayBack] Global Trade Item Number – Wikipedia
- [WayBack] API Documentation – Outpan Developers
Legacy API
Get Product Information
GET https://api.outpan.com/v2/products/[GTIN]?apikey=[YOUR API KEY]
Add Product Name
POST https://api.outpan.com/v2/products/[GTIN]/name?apikey=[YOUR API KEY]
Required POST parameters:
name: The name you would like to add for this product.
Add Product Attribute
POST https://api.outpan.com/v2/products/[GTIN]/attribute?apikey=[YOUR API KEY]
Required POST parameters:
name: Name of the attribute you would like to add for this product.
value: Value for the attribute you would like to add for this product.
- [GTIN] is the barcode number (ISBN, EAN, UPC, …) of the product you’re looking up.
- All API calls must be done via HTTPS. Plain HTTP calls will be rejected.

A change of FetchOptions.CursorKind from ckAutomatic to ckDynamic does the trick.
did fix this issue:
I stumbled about a problem regarding FireDAC and MSSQL 2016. The table has four fields, one being of type varbinary(max). When I omit this blob field from the SELECT, I can update any field without problems using the edit and post methods of TFDQuery. It is only when I include that blob field in the SELECT, I cannot update the other fields anymore (the blob is not changed). The post runs into a timeout. It seems that the table is somehow locked. That guess is backed by the fact that even a simple UPDATE query executed from Management Studio is also blocked until I reset my application inside the debugger.Interestingly an INSERT runs without problems.
