I am testing out DynamoDB for a serverless app I am building. I have successfully modeled all of my application's query patterns except one. I was hoping someone could provide some guidance. Here are the details:
Data Model
There are three simple entities: User (~1K records), Product (~100K), ActionItem (~100/product).
A User has a many-to-many relationship with Product.
A Product has a one-to-many relationship with ActionItem.
The Workflow
There's no concept of "Team" for this app. Instead, a user is assigned a set of products which they (and others) are responsible for managing. The user picks the oldest items from their products' action item list, services the item and then closes it.
The use case I am trying to model is: As a user, show me all action items for products to which I am assigned.
Any help would be greatly appreciated.
Really only two options...
If you can store the list of products within the 400KB limit of DDB record, then you could have a record like so...
Hash Key: userID
Sort KEY: "ASSIGNED_PRODUCTS"
Otherwise,
Hash key: UserID
Sort key: "#PRODUCT#10001-54502"
userID in the above might be the raw userid, or if using a GSI, might be something like "#USER#user-id"
I have two collections users and uploads. The user collection shows details about the users that have registered to the app. It contains details about the user such as name, userid and following which is an array. The following array contains list of people that the user is following as shown here.
The uploads collection has the posts that are made by the users. Each document in the uploads collection has details such as the postid, post and name of the user who posted it as shown here.
I want to get only the uploads made by the users whom they are following.
For example, Sally follows three people Sam, Thomas and Ellie. I want Sally to get only the uploads that
are made by either of these three people from the uploads collection. Any help would be appreciated. Thank You
I think this might be what you're looking for. You could fetch the users' following array and then use that array to fetch uploads containing people from the following. As a sidenote I'd recommend the userId instead of the name of the user as these might not be unique.
I need to extract all the synonym values for a particular entity. For example, I have an entity named Vehicle with values Car and Bus. For Car I have three synonyms, Mercedes,Volvo and Audi. Now what I need is when the entity Vehicle is detected in the user input for a value Car, I want to extract all the three synonym values present for Car. I know #Vehicle.literal will return the exact synonym value detected in the user input. But how can I retrieve all the synonyms for a particular entity value?
You can use the Conversation API to get information on an entity and its metadata. That information is not available in a dialog context itself.
IMHO a better way would be to use a database or similar to match up the detected entity with a list of synonyms. Usually, Conversation service is not used on its own, but part of a solution. The app server could perform the lookup if flagged. Take a look at the dialog actions for that. Or this suggestion on using the method of replaced markers in an answer.
Basically you can not extract the synonyms.One thing yiu can do is to create another entity with values as your car names and synonyms as vehicle.So that whenever a vehicle is input it will give you all the entity values.
I have a data model like this:
Person node
Email node
OWNS relationship
LISTS relationship
KNOWS relationship
each Person can OWN one Email and LISTS multiple Emails (like a contact list, 200 contacts is assumed per Person).
The query I am trying to perform is finding all the Persons that OWN an Email that a Contact LISTS and create a KNOWS relationship between them.
MATCH (n:Person {uid:'123'}) -[r1:LISTS]-> (m:Email) <-[r2:OWNS]- (l:Person)
CREATE UNIQUE (n)-[:KNOWS]->[l]
The counts of my current database is as follows:
Number of Person nodes: 10948
Number of Email nodes: 1951481
Number of OWNS rels: 21882
Number of LISTS rels: 4376340 (Each Person has 200 unique LISTS rels)
Now my problem is that running the said query on this current database takes something between 4.3 to 4.8 seconds which is unacceptable for my need. I wanted to know if this is normal timing considering my data model or am I doing something wrong with the query (or even model).
Any help would be much appreciated. Also if this is normal for Neo4j please feel free to suggest other graph databases that can handle this kind of model better.
Thank you very much in advance
UPDATE:
My query is: profile match (n: {uid: '4692'}) -[:LISTS]-> (:Email) <-[:OWNS]- (l) create unique (n)-[r:KNOWS]->(l)
The PROFILE command on my query returns this:
Cypher version: CYPHER 2.2, planner: RULE. 3919222 total db hits in 2713 ms.
Yes, 4.5 seconds to match one person from index along with its <=100 listed email addresses and merging a relationship from user to the single owner of each email, is slow.
The first thing is to make sure you have an index for uid property on nodes with :Person label. Check your indices with SCHEMA command and if missing create such an index with CREATE INDEX ON :Person(uid).
Secondly, CREATE UNIQUE may or may not do the work fine, but you will want to use MERGE instead. CREATE UNIQUE is deprecated and though they are sometimes equivalent, the operation you want performed should be expressed with MERGE.
Thirdly, to find out why the query is slow you can profile it:
PROFILE
MATCH (n:Person {uid:'123'})-[:LISTS]->(m:Email)<-[:OWNS]-(l:Person)
MERGE (n)-[:KNOWS]->[l]
See 1, 2 for details. You may also want to profile your query while forcing the use of one or other of the cost and rule based query planners to compare their plans.
CYPHER planner=cost
PROFILE
MATCH (n:Person {uid:'123'})-[:LISTS]->(m:Email)<-[:OWNS]-(l:Person)
MERGE (n)-[:KNOWS]->[l]
With these you can hopefully find and correct the problem, or update your question with the information to help others help you find it.
i'm having a little problem in my project. i'm using ADO.Net Entity Data Model,
let's say i have 2 Tables:
Offices : a. id
b. Name
Requests: a. rid
b.fname
c.lname
d.mobile
i want the requests table will have a relations to the offices table that each row in requests will have the id of the one of the tables.
i tried to do 1 to many relations but it didn't work , i just couldnt add data to the table.
thanks for your guidence
Your Requests table needs to have a field to relate back to the offices table. Which typically should be named OfficeID or something similar. Add that field and create the relationship from Offices.ID to Requests.OfficeID and it will work fine.
