QUESTION
I have an application that is using Event Sourcing and Command Query Responsiblity Seggragation Pattern. Development of the Command part is complete and I have to decide how should I implement the Query part.
My system deals with customer orders, so when event arrives for an order, that order processed with orderId and order payload. The thing is, in this form only whay to query the orders is over orderId so I can't ask a question like give me all the order in the system with status OPEN.
For this part I have to use the query part, my potential technology implementations for the query part, a classical solution like PostGre DB or more elegant way in my opinion Solr/Elasticsearch.
I have a basic knowledge/experience about Solr/Elasticsearch and I want to use this opurtunity to learn more but here comes my dilema. Some other department in our company is already working with Elasticsearch and a colleage from that deperatment told me, updates in elasticsearch is not a good idea, I didn't quite understand his argumentation, so I like to ask here what I am planning to do so you can tell me, it is a bad idea or Solr is better suited for it.
I am planning every status change for my order to send as an update for Elasticsearch, so it will look like the following.
id Status Customer Items orderId1 -> order.SUBMITTED order.Customer order.Items orderId1 -> order.CHANGED order.Customer1 order.Items orderId1 -> order.PROCESSING order.Customer1 order.Items orderId1 -> order.ON_DELIVERY order.Customer1 order.Items orderId1 -> order.COMPLETE order.Customer1 order.ItemsAs you see, I have to send several updates for orderId, to Elasticsearch/Solr.
So my colleague told me, Indexed Documents in Elasticsearch are immutables, when I send order.SUBMITTED Event to be indexed, it will create the document but order.CHANGED Event will not update the document but create another one. Now I can't quite judge the consequence of this, for my Business Case (I will ask orders of my Customer1 and I will see Status SUBMITTED and CHANGED, 2 records as query response) or operational (additional load and storage).
Did I understand correctly the behaviour of Eleasticsearch? If yes, will Solr behave any different?
If understood correctly an both will behave same, can I design anything differently that it would help reach my goals.
Finally I have no problem using PostGre for this solution, I just tough Elasticsearch or Solr would be a more natural choice for this problem. What do you think?
Thx for answers.
...ANSWER
Answered 2022-Feb-28 at 09:27You colleague is partially correct, about the costly updates in Elasticsearch(ES) and updates being immutable, but it doesn't mean ES is not suitable for system with frequent updates, in fact due to its scalability and distributed nature its preferred choice and being used in high-throughput and low latency systems(including the search systems). There are few misconception you have, and I would try to explain them.
- Both ES and Solr are based on Lucene, and costly updates or immutable updates are the property of Lucene, so it doesn't matter whether you choose ES or Solr, you will underlying using Lucene and will have same update mechanism.
- Updates are immutable it doesn't mean that your old status of Order will always be in the index, So for example initially your order status is
SUBMITTEDand later you update it toCHANGED, so even its immutable but when you query the order status, you will get the latest status(if refresh Happened on the index, default is 1 sec in ES), Apart from permanent deletion of old documents(Happens during the merge process, explained in #3), ES marks old document as deleted(soft delete by updating a boolean flag delete, on updation of document), due to this during your search these soft deleted documents are not returned. - ES periodically deletes the old document, so in your case
orderstatusSUBMITTEDwill be deleted from index during merge process, so that old documents are deleted, and your index size doesn't grow.
Also its very important to understand, that this immutable updates provides a huge benefit to improve the search/read performance as now these segments(which contains the documents in ES) can be used in multi-threading env as well as can be cached due to immutability reasons.

QUESTION
I'm creating a school schedule generator and I'm getting an exception from one of my constraints which checks that all students have lunch breaks every day.
I'm using the constraint stream Java API. My constraint compiles (obviously) and looks like this:
...ANSWER
Answered 2021-Oct-31 at 07:56Generally speaking, if your constraint compiles and the code still throws ClassCastException at runtime, you should expect the bug to be on the OptaPlanner side. Unless you are willing to look at the Drools executable model, there is nothing for you to debug there.
I recommend refactoring the constraint to look like this:
QUESTION
I've been using Sequence in type hints for sequences including mutable lists. Now I've just discovered that there is also MutableSequence. As far as I can tell, Sequence is a superclass of MutableSequence, i.e., Sequence includes both mutables like list and immutables like tuple, while MutableSequence only includes the former.
Two questions:
- Is this correct? (I'm pretty sure it is, but I haven't found any explicit statement to this end.)
- If so, is there an immutable equivalent to
MutableSequencethat includes, e.g.,tupleandstr, but notlist?
ANSWER
Answered 2021-Oct-29 at 16:02Yes.
No — in Python, you can only define interfaces (of which
SequenceandMutableSequenceare two examples) in terms of the presence of certain methods/behaviours; you cannot define an interface in terms of the absence of certain methods/behaviours.
I would recommend reading the source code for collections.abc, which I personally find much more illuminating than the documentation.
QUESTION
I've generally used immutable value types when writing java code. Sometimes it's been through libraries (Immutables, AutoValue, Lombok), but mostly just vanilla java classes with:
- all
finalfields - a constructor with all fields as parameters
(This question is for java 11 and below, given current spark support).
In Spark Sql, data types require an Encoder. Using off-the-shelf encoders like Encoder.bean(MyType.class), using such an immutable data type results in "illegal reflective access operation".
I'm curious what the spark sql (dataset) approach is here. Obviously I could relax this and make it a mutable pojo.
Update
Looking into the code for Encoders.bean it really does have to be a classic, mutable POJO. The reflection code looks for appropriate setters. Further (and this is documented) the only supported collection types are array, list and map (not set).
ANSWER
Answered 2021-Oct-20 at 15:31This was actually a misdiagnosis. The immutability of my data type was not causing the reflective access issues. It was a JVM 11+ issue (mostly noted here) https://github.com/renaissance-benchmarks/renaissance/issues/241
By adding the following JVM arguments everything is working correctly:
--illegal-access=deny --add-opens java.base/java.nio=ALL-UNNAMED --add-opens java.base/sun.nio.ch=ALL-UNNAMED
QUESTION
I'm using immutables.org library and want to add Javax annotation validation. But I noticed that the validations are not being carried to the generated class. I thought that immutables.org were compatible with validations annotations. I have spring-boot-starter-validation and javax.validation dependencies.
immutable
...ANSWER
Answered 2021-Oct-14 at 09:55- Really,
@Validshould not be set in a model for field or class, only for controller method's argument. @Sizeis not available forintfield, you need to use@Rangeor@Min.- In your interface you annotated the abstract methods, not fields. How does validator relate a validating fields
ageandnamewith methodsage()andname()? When they will be called (their implementations) than a validator will try to validate them. But not a model's fields.

I have written a custom annotation processor and configured with maven compiler plugin as shown below, I am facing issue with Immutables annotation processor which is in my application class path. When I add my annotation processor via maven compiler plugin, the Immutables is giving compilation errors. I need Immutables as well in my project.
...ANSWER
Answered 2021-Oct-12 at 02:30Package your annotation processor into a JAR and include that JAR as a
compilation dependency. Be sure to add

QUESTION
Python map function works both on mutables and immutables, it returns new iterable object(for python 3.x).
However I would like only to change the values (of a mutable object eg. list, np.ndarray), in the nice and consistent manner similar to the map().
Given following function:
...ANSWER
Answered 2021-Sep-29 at 09:52No, it does not. But you could easily make one, as long as the object you are willing to modify is a Sequence (specifically, you would need __len__, __getitem__ and __setitem__ to be defined):
QUESTION
I am working on a project and have shifted my environment from local windows to a linux server (via SSH). I only have limited access as the host server is from my college, I've installed many packages without issues (both with and without virtualenv). I'm working on Python 3.6.9.
I was able to install spacy and import it but I need to use the en_core_web_sm package which has to be installed additionally using the command python3 -m spacy download en_core_web_sm. However, I consistently face a PermissionError as seen in the logs below.
Why am I facing this error? Is it because I don't have administrator access on the /usr level (refer to last line of logs)? If yes, how come only this package in particular requires a higher level access? If no, are there any workaround for me to install the package, or do I need to contact the server administrator?
...ANSWER
Answered 2021-Aug-25 at 08:45It seems all other packages are installed under your user /home/jiayi/.local/python3.6/lib and this one tries to install itself globally in /usr/local/lib/python3.6/, not sure why. I guess you can give it installation folder or something.
Look here Where does spacy language model download?
