sql server – Strategy for transaction log backup

I am trying to come up with solution for restoring database with one full backup file and then with hourly transaction logs that are going to be created each hour thru FTP site.

So, here is a scenario.

I connect to data provider’s FTP site, and get a full backup file first and restore database with 24 transaction logs on a daily basis. So, I will do a nightly run (around 12 am) to update all transaction logs from pervious day’s data.

I learned that there is an option called “Standby” option, so I tried full back up with “Standby”, but it appears that I cannot do this because database needs to be upgraded. (Are we referring to database of data provider?)

I got this error when I tried Restore Full backup with “Standby” mode.
enter image description here

So, I am coming back to the way of restoring database using “NoRecovery” for Full backup and then for all other transaction log files (because with “Recovery” mode, I cannot restore additional ones later, correct?).

But, I need to access database to read data on a regular basis and to query the data.

What should I do?

authentication – Auth strategy for local Docker services

I’m trying to choose an authentication/authorization strategy for some Docker services that all run on a single Linux IoT device. There are N number of 1st party services, and a single 3rd party service. Each running in their own Docker container, and all on the same shared Docker Network to be able to communcate with each other.

I need to be able to authorize some endpoints being called inside the 1st party services. Really, I just need to make sure the 3rd party service can’t call certain endpoints on the 1st party services.

Since each service has its own DNS entry within Docker, would it be viable to use the caller endpoint for authentication? For example, since I know a call from ‘my-service-one’ is one of the first party services, any requests from it will get the ‘Admin’ role and can make calls to the /admin endpoint.

I have some other ideas, but since this is all running on an IoT device, I want a way for the services to
be able to run when there is no internet connection for an extended period of time.

development strategy – Yet another child theme building question: Frankenchild themes

I’m about to build a new site based on a theme close to what I’m looking for. I understand the concepts around child theming & have read the caveats about overriding php or css files like the one described here.

Using such workarounds and calls from functions.php, is it possible to build a “Frankenchild theme” by taking chunks of a second (would-be parent) theme and patching them into the child theme? I’m not quite asking about creating a child of two parents; the child would only have one “official” parent.

As an example: Start with a Gantry basic theme and add custom taxonomy search capabilities & search results formatting (say a card-based carousel). Is that stepping over the line into plugin development?

java – Architectural problem for class combination (cartesian product) for save format strategy

Hello to everyone and thank you for any suggestion.

I have a family of subclasses of Track (Track is abstract).
Every concrete Track has a different number and types of fields (attributes) that extend the basic abstract track-fields.

Then I have a family of file-types that implement some methods (saveRow() etc..).
Every file is presumed to have different type of row-formatting (imagine csv tabs, headers etc..)

ex:

  • SimpleTrack: double lat, double lon, Calendar dateTime.
  • DetectionTrack: (as SimpleTrack) + boolean detection.
  • ..
  • CsvFile
  • TxtFile

When I create a new (X)Track and a (Y) file, they are independent by nature, but.. the row is a cartesian product of track & row types.

EDIT
(to be more clear): How can I have many concrete-tracks in one hand and many FileTypes in the other hand, and create well-formatted-rows (differents for every file) by tracks which have different data (columns, headers..)?
es:

  • XtrackRow(double a, double b, Calendar date) -> to -> CVSfile (tab delimited with headers)
  • XtrackRow(double a, double b, Calendar date) -> to -> TXTfile (formatted columns and title)
  • YtrackRow(double a, string, b, int c, double e) -> to CSV ..
  • YtrackRow …. -> to -> docx file (with another kind of table or tabulation)
    ..

I see two kinds of solutions:

  1. Tracks send (right)-formatted row to file: every track has to know which kind of format apply (to rows) to give them to save to any specific type of file.
  2. Tracks send raw-data to any kind of file which is responsible to format them: in this case, the file-class must know wich kind of data has to format (every track has diffrent contents, columns, headers..). Moreover, every track-class has to send different number and types of parameter..

The second solution seems to be more fitted to the Single-Responsibility principle.. but I have no Idea how to implement it.

I tried to use Bridge Pattern to solve this problem (using first solution):

abstract class Track{
  ...
  FileInterface file;

  Track(FileInterface fileType){
    this.file = fileType;
  }

  abstract String formatConcreteTrackRow();
  
  void sendRow(){
    String rowToSave = formatConcreteTrackRow();
    file.saveRow(rowToSave);
  }
}

By this way the problem is not already solved, because every concrete-track has to implement a set of methods which returs right formatted rowString: one for every file-type.
If I use a Strategy Pattern:

class SimpleTrack extends Track{
  ...
  RowFormatStrategy rowStrategy;
  
  @override
  String formatConcreteTrackRow(){
    return this.rowStrategy.getRowString("args")
}

but in this case.. every concrete-track require a different StrategyInterface, because every concrete-track has different number and types of arguments to elaborate..
If I do not use Strategy Pattern and I define a set of methods (formatCsvRow(args),formatTxtRow(args)..) I need to include a switch(fileType) loop to choose which method to use.. breaking SOLID principles.. 🙁

Moreover..
how to impose, for every new concrete-track to have right row-format methods for every existent file-template-row?
and.. How to impose, at the same time, for every new file-class to impose new templates and relative methods in every existent concrete-track?

To be honest, it’s also quite reductive impose formatConcreteTrackRow to be a String, but it’s over and over the main problem.

I’m not interested to maintain this kind of class structure, this is only the best solution I found trying to follow SOLID principles. If you can show me a better solution, my intent is to study and understand SOLID procedures to solve these kind of purposes.

(I looked around for similar questions, but I’m not even able to define the specific problem itself..)
Thank you very much.
