QUESTION
I need to count daily orders per user. The data may arrive late for quite a long time. So i think i can use a MapState[String,Long] for key is date and value is the order num according to the date to store the count.But as time goes by, the key-value will be one more per key per day and the state size could be too big someday. Since the data won't be late for longer than a day ,i just need to store two days of data. In this situation, i need to remove the earliest date when the size of MapState[String,Int] reaches 3. But i find out that there isn't a size method for fink MapState.
I know i can use iterator to achieve this and this is exactly what i did. But since the java.util.Map has size method, why isn't there a size method for flink MapState?
...ANSWER
Answered 2022-Mar-31 at 14:05This is because with the RocksDB state backend the underlying representation of MapState doesn't allow for an efficient implementation of a size method.

How do I send HTML email so that it will look nice with Bootstrap 4? When I send mail it looks nice, but when receiver gets it it looks bad. here's code:

Answered 2021-May-24 at 10:41I am guessing you are using bootstrap. Use bootstrap for e-mail instead. Web frameworks will NOT play nicely with e-mail. HTML e-mail have different rules and best practices on how to develop markup for it, than classic web sites.

QUESTION
I am using following three test cases to test the behavior of upsert-kafka
- Write the aggregation results into kafka with
upsert-kafkaformat (TestCase1) - Using
fink table result printto output the messages.(TestCase2) - Consume the Kafka Messages directly with the consume-console.sh tool.(TestCase3)
I found that when using fink table result print, it prints two messages with -U and +U to indicate that one is deleted, and the other is inserted, and for the consume-console, it prints the result correctly and directly.
I would ask why fink table result print behaves what I have observed
Where does -U and +U (delete message and insert message) come from, are they saved in Kafka as two messages? I think the answer is NO, because I didn't see these immediate results.
when consuming with consumer-console.
ANSWER
Answered 2021-Jun-01 at 15:38With Flink SQL we speak of the duality between tables and streams -- that a stream can be thought of as a (dynamic) table, and vice versa. There are two types of streams/tables: appending and updating. An append stream corresponds to a dynamic table that only performs INSERT operations; nothing is ever deleted or updated. And an update stream corresponds to a dynamic table where rows can be updated and deleted.
Your source table is an upsert-kafka table, and as such, is an update table (not an appending table). An upsert-kafka source corresponds to a compacted topic, and when compactions occur, that leads to updates/retractions where the existing values for various keys are updated over time.
When an updating table is converted into a stream, there are two possible results: you either get an upsert stream or a retraction stream. Some sinks support one or the other of these types of update streams, and some support both.
What you are seeing is that the upsert-kafka sink can handle upserts, and the print sink cannot. So the same update table is being fed to Kafka as a stream of upsert (and possibly deletion) events, and it's being sent to stdout as a stream with an initial insert (+I) for each key, followed by update_before/update_after pairs encoded as -U +U for each update (and deletions, were any to occur).

QUESTION
I have 1452 independent tasks in a flink job. It reads from kafka. Then do some transformation using flatmap and then sinks in hdfs files. Kafka and and flatmap has parallelism of 20 each and i have 1450 independent sink each having parallelism of 1. As maximum parallelism is 20 here. Flink creates only 5 taskmanagers when i use 4 slots per taskmanagers. As number of total tasks in job is very high i need more taskmanagers to be created.
As of now i am giving more parallelism(100) to one of the sink task so that i get desired number of taskmanagers(which is not a proper way) but it leads to all sink tasks(except the one with 100 task slots) to be created on only one taskmanager and remaning taskmanager is used by other tasks.
So i need some way to instantiate desired number of taskmanagers in fink and some way to distribute sink tasks into all taskmanagers.
...ANSWER
Answered 2020-Nov-09 at 07:29The simpliest way to isolate slots and force the YARN to provide additional task managers and slots will be to use Slot Sharing Groups for operations you want to isolate. By default all operations are put into the default slot sharing group and therefore all your tasks share the same slot.
To do it, just specify a different slot sharing group for different jobs after operators you want to isolate:

About a couple of weeks ago, I started learning about Regular Expressions. For practice, I thought of extracting different topics(along with their respective times) present in the description section in youtube videos(youtube uses this to slice the progress bar and each slice represents different topic). Example: for https://www.youtube.com/watch?v=E4M_IQG0d9g, the description looks something like below

.map(match => match.match(new RegExp(re, 'i'))) // split into timestamp and string

I have a JSF application with PrimeFaces that I'm updating to PrimeFaces version 8 (currently using version 7).
After updating I have a strange behaviour with a TextEditor in a dialog. I open the dialog with a commandLink and update the dialog to refresh its contents. When I do this I get an error on the JavaScript console.
...ANSWER
Answered 2020-Aug-04 at 17:29OK the issue was fixed in 6.2 here: https://github.com/primefaces/primefaces/issues/2802
However when QuillJS 1.3.7 was upgraded for a security CVE this change was lost.
I just submitted a PR to fix this hopefully for 8.0.4 and 9.0.
QUESTION
I have created an object using new in a switch case. The object is assigned to an element of an array of pointers. While in the case I am able to call a method on that object, but outside the case it seems I cannot. It just doesn't do it. I have a function to set the elements of the object which I can call while within the case, but outside of the switch case I don't seem to be able to call that element with a method to show the contents of the object. I supposed there might be a scope problem here, but the array is declared outside of the switch case.
Here is a code snippet:
...ANSWER
Answered 2020-Jun-13 at 23:42It is very simple: in your case clauses, you immediately destroy the object using delete.
That is why you can not call any of its methods later.
Notice, that what you are putting in the array is only a pointer to the object.
The exact same pointer stored in bee variable.
Once you call delete on it, it becomes invalid.
You are not creating a copy of the object!
