That means if it’s a photo with mountains, maybe match it with some mountain sayings. The best way to write short quotes for Instagram is to look at your photo and match the caption to what the photo shows. Most importantly, a short saying is succinct. Short captions on Instagram can still be fun, inspiring, creative, and even thought-provoking. Sometimes, we don’t have the time to write a long Instagram caption. Not every social media post requires us to bear our heart and soul. A picture can be worth a thousand words and may not need a long Instagram caption. It’s a matter of preference when it comes to IG captions. Some of our Instagram captions are long, while some require short quotes for Instagram. You can use this space for quotes to share your feelings, ask questions, or relay information to your audience. The right words can help convey your message, make a joke, or share your feelings. However, there is a difference between a bad Instagram caption and a good Instagram caption.
That small section of text beneath your Instagram photo can convey a lot. The first is for a specific "student", the second for all the "students" on the subject in status = "Active".You almost certainly know about an Instagram caption. Select * from grades where subject = 'English' and status = 'Active' allow filtering Select * from grades where id = '1093' and subject = 'English' and status = 'Active' So, if you want to query on "status" you will b able to query in two different ways:
This means that if you have composite key = (id, subject, status, date) and want to query "status", you will need to restrict "id" and/or "subject" ("or" is possible in case you use "allow filtering", i.e., you can restrict only "subject" and do not need to restrict "id"). You always need to "Constraint"/"Restrict" the previous element of the primary key if you are to use multiple elements of the composite key. You cannot swap elements on the primary key list on the queries (that is more a SQL way of thinking). Cassandra data model aims (and this is a general NoSQL way of thinking) at granting that queries are performant, that comes to the expense of "restrictions" on the way you store and index your data, and then how you query it, namely you "always need to restrict the preceding part of subject" on the primary key. That looks all normal behavior according to Cassandra Composite Key model ( ). I am always ONLY able to query using either the Primary Row key or the second key, considering above example, if I swap subjects and status in Primary Key list, I can then query with status but I get similar error if I try to do by subject or by time.Īm I doing something wrong? Can I not query data using any other composite key in CQ元? Just to experiment, I shuffled the keys around keeping 'id' as my Primary Row Key always. SELECT * FROM grades where status = 'Active' ALLOW FILTERING //gives an errorīad Request: PRIMARY KEY part status cannot be restricted (preceding part subject is either not restricted or by a non-EQ
SELECT * FROM grades where subject = 'English' ALLOW FILTERING //works fine When I try and access the data, SELECT * FROM grades where id = 1098 //works fine These are my queries: CREATE TABLE grades (id int, I want to query data filtering by composite keys other than Row Key in CQ元.
