Is there a way to have Paw sort JSON response key-value pairs by key alphabetically when displayed? This would make it easier to find entries at a glance without resorting to using a key path.
Paw has a "Sort Keys" option under Preferences -> Formatting, in the JSON section.

Our MarkLogic based web-application mostly uses cts.jsonPropertyValueQuery to access needed information.
We want to provide the possibility of wildcard searches against specific JSON properties.
What is the best way to do it?
Turning on one of the wildcard indexes for the whole database is not an option.
I figured out that adding a "wildcarded" parameter to the query itself may solve the problem:
cts.search(cts.jsonPropertyValueQuery("inventor", "R?th", ["wildcarded", "whitespace-sensitive"]));
But it may work slow due to the absence of indexes. Is there any way to create wildcard indexes only for that specific JSON property?
You could create a Path Field with an XPath to the inventor JSON field (and even for //inventor) and configure the field to have wildcard indexes, and then use a field query: cts.fieldValueQuery or cts.fieldWordQuery.
everyone!
I have the following situation: client sends attributes, which he wants to retrieve from table, for example "Id, Name, Price", and I should send them , having been mapped them before. The problem is, how to find out what are the types of given attribute? I want to know where the data of Price attribute is stored: val["Price"].N or val["Price"].S or somewhere else? Is there any way to find it out?
Thank you for any advice!!!
I am not familiar with the .net SDK specifically, but if you are looking for what data type each attribute is stored in DynamoDB, you could do the calls with the low level client in the SDK, as opposed to the DocumentClient. The low level client returns DynamoDB's native JSON format and will tell for each attribute if it is a string, number, map, etc.
The extractAvroMetadata indicates in its properties section that for the propoerty 'Metadata Keys' we can use a comma-seperated list to indicate the fields to get for the avro schema.
Has anyone already used that option since when I mention a list like doc,namesapce it does not work ?
The documentation says this:
"A comma-separated list of keys indicating key/value pairs to extract from the Avro file header. The key 'avro.schema' can be used to extract the full schema in JSON format, and 'avro.codec' can be used to extract the codec name if one exists."
So you can only use keys that are in the header, or the two mentioned keys.
If I make a HTTP POST to riak, i.e http://localhost:8098/riak/mybucket along with JSON-encoded data {name: "John Doe"}, the object is saved as expected.
However, this data will be assigned to an id set by Riak automatically, something like WAqRNgxZl10FK0F3FLuorByNHgN.
Is it possible to make Riak return this id in the response of the HTTP POST?
According to the Riak documentation, it returns the new key/ID in the Location header.
In the output, the Location header will give the you key for that
object. To view the newly created object, go to
“http://127.0.0.1:8091/Location” in your browser.
You can see the docs here - Scroll down to "Store a new object and assign random key "
Reading about Http Post on Wikipedia it states that This is a format for encoding key-value pairs with possibly duplicate keys. Is this correct and if so what is the reasoning? Why would a client ever post duplicate keys and if a duplicate key is posted how is the correct corresponding value returned on server side?
To submit multiple values for the same thing.
In PHP, for example, you can name multiple input fields somedata[]. All values of the input boxes are then put in an array named somedata.
