QUESTION
I am trying to speed up the querying of some json data stored inside a PostgreSQL database. I inherited an application that queries a PostgreSQL table called data with a field called value where value is blob of json of type jsonb.
It is about 300 rows but takes 12 seconds to select this data from the 5 json elements. The json blobs are a bit large but the data I need is all in the top level of the json nesting if that helps.
I tried adding an index of CREATE INDEX idx_tbl_data ON data USING gin (value); but that didn't help. Is there a different index I should be using? The long term vision is to re-write the application to move that data out of the json but that is something is at least 30-40 man days of work due to complexity in other parts of the application so I am looking to see if I can make this faster in short term.
Not sure if it helps but the underlying data that makes up this result set doesn't change often. It's the data that is further down in the json blob that often changes.

Answered 2022-Feb-12 at 12:47Like a_horse already advised (and you mentioned yourself), the proper fix is to extract those attributes to separate columns, normalizing your design to some extent.
Can an index help?Sadly, no (as of Postgres 14).
It could work in theory. Since your values are big, an expression index with just some small attributes can be picked up by Postgres in an index-only scan, even when retrieving all rows (where it otherwise would ignore indexes).
However, PostgreSQL's planner is currently not very smart about such cases. It considers a query to be potentially executable by index-only scan only when all columns needed by the query are available from the index.
So you would have to include value itself in the index, even if just as INCLUDE column - totally spoiling the whole idea. No go.
You probably can still do something in the short term. Two crucial quotes:

Data typeThe json blobs are a bit large
Drop the cast to json from the query. Casting every time adds pointless cost.
One major cost factor will be compression. Postgres has to "de-toast" the whole large column, just to extract some small attributes. Since Postgres 14, you can switch the compression algorithm (if support is enabled in your version!). The default is dictated by the config setting default_toast_compression, which is set to pglz by default. Currently the only available alternative is lz4. You can set that per column. Any time.
LZ4 (lz4) is considerably faster, while compressing typically a bit less. About twice as fast, but around 10 % more storage (depends!). If performance is not an issue it's best to stick to the stronger compression of the default LZ algorithm (pglz). There may be more compression algorithms to pick from in the future.

QUESTION
ANSWER
Answered 2021-Sep-30 at 03:21I see the problem is within your fromJson method:
When creating named constructors, you have 2 possible syntaxes to it:
1. Quick define some params with initializers, without access tothis
In this situation, imagine you have a subclass called PickUpGameDetails.noReview where you'd create a fixed userReview object.
In this case, you wouldn't process any extra params, only simplify the constructor using initialiser for some params. For this to work, you would add the initialiser before the {, using the :, being something like this (in this case you wouldn't even need to create the context with { }, unless you want to do extra operations besides the initialisers):
QUESTION
I want to create a GUI in C# that will be used to run keytool on cmd.exe behind the scenes to create a keystore, including a key, and certificate data.
Input data then requires
- Keystore path
- Password
- Key alias
- Key password
- Validity
- Certificate info (cn, ou, o, l, st and c)
Unfortunately people may type special characters in their passwords and also space is allowed in the certificate info.
Overall I am worried someone may input some information somewhere that can result in a disastrous command running behind the scenes once this is called (like rm -rf *).
Is there a way to pass a java properties file with the input information to keytool or is there any way that I can safely escape all the data that is passed as string parameters to keytool?
I could not find any type of file that keytool could take, even in separate steps, that would eliminate this issue.
here's the unsafe code (warning: IT'S UNSAFE!!):
...ANSWER
Answered 2022-Feb-18 at 23:39I believe that invoking the keytool binary directly instead of cmd.exe would do the trick if you don't want the user to inject shell commands.

QUESTION
I have a file named check-rates that holds some useStates() that the users will input in order for me to execute and return for them an estimated value for their shipment by using DHL API.
In my nodejs express server, I am trying to access these useStates() with req.body but when I console log the constants I always get them as undefined. I need these values that the user enters so that the API becomes dynamic for each customer/user that uses my website and not fixed values (as I have them now.)
What am I doing wrong?

I am using UPS API for CANADA and USA countries, the shipment origin will always be Canada.
The below is a request I am passing to get the UPS rates and to get an Estimated Arrival Time. If I pass the below request parameters for Canada address it works fine in response, but if I pass an US address in UPS API request parameters it throws an Invalid Shipment Contents Value error.
Here are the UPS API Request and its Response that works fine for the Canada address, but does not work for any US addresses:

QUESTION
I have overtaken an internal software tool from a former employee at our company that is written in NodeJS and is connected to a salesforce shop system currently.
Unfortunately, I'm relatively new to NodeJS and my job currently is to connect the tool to a new shopware 6 (sw6) system and have all the functionality mapped to the new shop system which are for example creating job postings on the shop system.
I have checked and established a connection to the sw6 in an isolated manner but I'm failing to have a job posted on the sw6 system end-2-end, beginning from the Jobposting form in the internal software tool to having a landingpage in the shop system for the created job.
I may share you the code of the function that I'm trying to adjust:

Answered 2021-Dec-06 at 15:38Luckily, I was able to find the problem just right now with some inspiration from this Post here: TypeError: circular structure to JSON starting at object with constructor 'ClientRequest' property 'socket' -> object with constructor 'Socket'
In the function for requesting the sw6 access token (shopwareAuth.getToken), which I had already adapted from the old salesforce token request function, I made use of the complete response from the OAuth2 query response which was wrong as only the res.data part was needed.
QUESTION
I am using a Native query in my JPA Repository to run INSERT query - because, I couldn't run a few queries through JPA.
...ANSWER
Answered 2021-Nov-28 at 16:58You cannot make the INSERT INTO statement return anything. Depending on your database's support, on that end you could execute multiple statements, e.g., INSERT INTO ...; SELECT ..., but Spring Data JDBC does not support this.
- What you can do is implement
saveNewUserand perform the insert then select, sequentially and synchronously. See this: https://docs.spring.io/spring-data/jdbc/docs/current/reference/html/#repositories.single-repository-behavior. - If your database supports it, you could create a stored procedure that performs the insert then select.

Answered 2021-Nov-26 at 16:48One option would be countrycode::countryname to convert the country names.
Note: countrycode::countryname throws a warning so it will probably not work in all cases. But at least to me the cases where it fails are rather exotic and small countries or islands.
