QUESTION
Should the MongoClient connection be closed every time the server shuts down?
I have seen the following code snippet and wanted to know if this is actually valid and should be done or if it's completely unnecessary to perform a closing on exit:
...ANSWER
Answered 2022-Apr-07 at 09:49Should the MongoClient connection be closed every time the server shuts down?
Yes, it is a good practice to close the connection. As for every connection, mongo DB does assign a thread for its execution. If you won't close it, it keeps using the resources on the DB server.
Node.js connections use the pool to connect to DB and it can be reused while it is not being used, but it is good practice to close the connection if you are exiting the script as it won't close the connection automatically.

Currently working on a React/Typescript/Firebase Firestore project. When writing Jest-tests for some actions/functions that are called from the UI, I ran into the following problem:

Answered 2022-Mar-24 at 08:37Thanks for confirming that I was looking in the right place (i.e. @firebase/rules-unit-testing). Finally figured out what the problem was, missed an "await" in createCompanyAndRating, so the firestore admin instance wasn't getting the data (and I though it was a admin config issue...) Thanks!
QUESTION
I'm currently building a reactive app using kotlin quarkus and mutiny, being new to reactive programming i wonder what's the best way to handle the following workflow :
- try to find an item in the database (dynamodb)
- if it exists return a value indicating this to the caller
- if it does not exists call the save service
- call an external service to get some data
- update the item in database with those data from the external service
- return a value indicating that the object has been created
Here's my code for now :

Answered 2022-Mar-16 at 08:22I don't believe your code does what you expect. If I understand correctly you need to "save" and "update" before emitting your result. So, you need something like (in Java, as my Kotlin is not great):
QUESTION
_Managed WP, GoDaddy _Tools available: in GD: "File Browser", "phpMyAdmin" (takes me to a URL UI). _phpMyAdmin:
- Has things like "Databases" "Status" "Ex/Import" "Variables" "Charsets" "Engines".
- Left tab has info_schema & server/site id in a drop down menu setup. One drop per item (schema & site/server). Two hierarchies.
- A console/terminal
- db client libmysql - mysqlnd 7.4.16
- I don't know how to control the webserver. I am trying to setup multisite network. Currently testing/configuring pretty permalinks. Instructions unclear. Can't find GoDaddy docs on server interaction. Console in phpMyAdmin only sends SQL queries, totally not helpful. This documentation assumes I am big-brain Dev.
- states
However, we can set our really cool permalink configuration directly by editing Nginx. We will use try_files directive so WordPress can start using pretty permalinks. Let’s see the configuration for WordPress installed on the root of your domain, and also on a directory called /blog

...ANSWER
Answered 2021-Dec-07 at 08:55Problem solved! There is a reason so many online articles talk about Apache and few talk about nginx (concerning GoDaddy, Managed WordPress, Multisite Network Install). The reason is because A) Managed WordPress from G-Diddy is incompatible with Multi-site Network installation. Why? The parts of the server and the control over directories needed to achieve Multisite Network install are x) not accessible x) non-existent do to lack of tools (this is why the monthly cost is lower). {I keep mentioning Multisite Network, that was the end-goal; Pretty Permalinks setup was a prerequisite to Multi-site). B) All Managed WordPress offers from GDiddy come with nginx so: no Apache, meaning !no!htaccess.php file exist! C) No Apache also means no cPanel, meaning, a bunch of other s**t doesn't exist too...
Resolution:- Upgraded to "WordPress with cPanel" (this is delivered on a Linux box, with Apache webserver + cPanel).

I used the mongo shell to convert these to hex, you can see that it is indeed the ObjectID you were looking for, it just looks strange in decimal

QUESTION
I have a MySQL database with German "Umlaute öäü" in a table and I need to write a Go app that reads the table, encode it to ISO-8859-1 and write it to a text file.
So far so good, but the encoding to iso-8859-1 is not working. I have tried to debug this.
Here some details and information:
MySQL The MySQL database is UTF8, also the table itself. Also other character sets should be fine, except the character_set_server, but I think this is not relevant here, it should be just a default for new databases as far as I know.
When I query the database with the following SQL, I get the correct UTF8 encoded text:
...ANSWER
Answered 2022-Jan-22 at 22:58After two days of completely lost, I found the root cause myself. Strange that it happened shortly after I posted the question here.
I wanted to try a different mysql server and therefore dumped the table. And then I have seen in the dump that each field has its own character set definition which was latin1 in my case.
So that explains why it was a strange result. I just created a correct encoded test table and it works now as expected.
Now I have to think how I can "repair" these encodings, maybe a dump/restore will do it, but that's a another story.
QUESTION
DynamoDB has multiple nodes and all nodes are equal: there is no single leader. I am assuming we have a DynamoDB instance and all the data can be stored on a single node. But we have several replicas for availability and redundancy.
So writing and reading can happen on any replica node. I am just curious, how DynamoDB client decides to which node the request should be sent? Or the application developer has to take care of this routing themselves and the DyanmoDB client simply forwards these requests to the DB node.
If someone could explain to me where this routing happens and could point me to the code where this routing is implemented, that would be a great help?
I am new to the DynamoDB and trying to understand how things work.
...ANSWER
Answered 2022-Jan-21 at 12:15Fundamentally this is an implementation detail that AWS handles - you won't find it in your Java code.
DynamoDB has multiple nodes and all nodes are equal: there is no single leader.
This is a misconception, the table is split up into partitions and each partition consists of three storage nodes. For each partition a storage node is selected that is the primary contact point for writes.
A few years ago there was an interesting talk by Jason Sorensen about the internals of DynamoDB at re:invent, you can see it on YouTube.
To summarise it, there is a fleet of request router instances that are aware of the storage nodes and how the hashing works. The storage router selects the leader node of the partition and writes data to it. As soon as two of the storage nodes acknowledge the write, the data is considered to be persisted.
