We have an importer running on a powerful, multi-core server. However, our Apache Camel routes are single threaded, which is a shame.
Our [camel] importer is a single-instance program. How can I make a specific route process the messages using multiple threads? The messages are atomic and are processed by a bean, which already does this in a thread-safe way. I am already happy if I could process batches (maxMessagesPerPoll) in threads and have idle time until the next poll takes place (after all, that's still better than sequential processing).
Here is one of the routes I would like to make multithreaded:

QUESTION
What I want to ask you is "Can one UITableviewcell
be used for multiple tableview
like viewholder that can use anytime for recyclerview in android?" what I used to do is in one viewcontroller
I have a tableview
with a custom Cell and gave its identifier as normal but if I trying to use another uitableview
in another Viewcontroller
with that cell that inside the previous tableview, it always gives me a blank cell with white background. is there a way to use it like that?
EDIT: Here is what my tableview look like when i've already set cellforrow for it already. Click to view and here what my cell look like Click to view cell and here are my code for different cell in a tableview, It'll work if i use use those 2 cell in current tableview
...ANSWER
Answered 2018-Aug-08 at 07:00Yes you can. You have to register it again for the new tableView
. It is just like how you create variables using the same type. This is also a class which can be used to create objects. Doesn't matter where you want to use it.
On the other hand if you are asking if instances of the same cell which are present in a tableView
can be reused in another tableView
, then the answer is no, because they have only been registered for that particular tableView
.
QUESTION
Good day!
I've run into a head burner. My client requires me to repurpose a python program to work with MySQL instead of Microsoft's SQL Server. I'm having trouble finding an equivalent solution in SQL.
I can't seem to create a proper update lock on a row. When two identical transactions execute simultaneously, they both read the row despite opening a transaction at the serialize isolation level, and with SELECT ... FOR UPDATE.
Maybe my code will explain it better:
...ANSWER
Answered 2018-Feb-25 at 03:43SELECT... FOR UPDATE
isolates transactions at different levels depending on your configuration. You can find more information https://dev.mysql.com/doc/refman/5.5/en/innodb-transaction-isolation-levels.html#isolevel_repeatable-read here.
But the most important thing in your code is that you have to be using DIFFERENT sessions for different transactions.
As stated here https://dev.mysql.com/doc/refman/5.7/en/lock-tables-and-transactions.html. If you run another transaction in the same session before a transaction is finished, it will be implicitly committed and it's what is leading to random results in your code.
What you are doing right now in your code is same as running two transactions in one terminal which would be not much different to just running everything in non-transaction.
You would need to create transactions in different connections through methods such as pooling in order to simulate different sessions.
QUESTION
I am trying to reload only the data that is first loaded on a page when the user clicks a button. I know how to refresh the page but I can't find any good documentation to what I am trying to do. Can someone please redirect me to the right place? Here is the code I have that refreshes the page when the refresh icon is clicked.. Take a look at the glyphicon refresh, that is where I can refresh the page but I am supposed to load the data back after a user deletes rows, I can't explain it to well but I even tried to do window.location.reload() but that isn't the correct way to load data back to the page.
Thanks

...ANSWER
Answered 2018-Feb-08 at 05:56One method would be to make a duplicate of bidtypes at the beginning, and restore the array from that duplicate when then refresh button is clicked.
QUESTION
I am making a project using Django and using Jinja for template design.
Prelude:
I have a file in localhost server and I don't know what kind of file is it.
So, how do I choose tags in html to show that file type is or

QUESTION
I have a app that has a UILabel that I would like to be updated by another swift class? The class is a service class and has no relation to the view controller with the UILabel but I would still like that service class to be able to update the label.
I think that this answer was what I needed but it does not work for Swift 3 and the text the label changes to is hardcoded which is not what I wanted either. I could not find anything else helpful about this.
