In RavenDB a curl command on ravenServer.com/databases/myApp/indexes
returns a nice list of all index definitions for the database.
For my disaster recovery scenario, is there a http command that can put them all back. Or will I have to parse each one out and issue the command outlined in the documentation?
My app is using the HttpApi and not using .Net to create indexes, or I would just push them all that way.
No, you have to create them one at a time.
Note that you can use the smuggler tool, which will do this for you.
It is a command line app that comes with RavenDB.

I'm using redis to store the userId as a key and the socketId as the value. What's more important is that the userId doesn't change, but the socketId constantly changes. So I want to edit the socketId value inside redis, but I'm not sure what node_redis command to use. I'm currently just editing by using .set(userId, mostRecentSocketId).
In addition, I haven't found a good node_redis API anywhere with a complete list of commands. I briefly looked at the redis-commands package, but it still doesn't seem to have a full list of complete commands.
Any help is appreciated; thanks in advance :)
The full list of Redis commands can be found at https://redis.io/commands. After finding a proper command it wouldn't be hard to find how is it proxied in binding ("api") you use.
Upd. To make it clear: you have Redis Server, its commands are listed at the doc I provided. Then you have redis-commands - it's a library for working with redis (I called it a "binding"). My point was that redis-commands may have not all the commands that redis-server can handle, and also the names of some commands can differ a bit. Some other bindings can offer slightly different set of commands. So it's better to examine the list of commands that Redis Server handles, and then select a binding that allowes calling that command (I guess all the bindings have set method)
I am learning Redis right now and one of the first things I did was trying to interactively issue commands to an online Redis server: http://try.redis.io/
The FLUSHALL command is well documented here: http://redis.io/commands/flushall and is also referenced in this SO answer.
But when I try to issue it, it is simply not recognized:
My question: Why? Where has it disappeared? After all, the documentation says it is:
"Available since 1.0.0."
The web interface at try.redis.io, while executing against a real Redis database, offers only a subset of the actual commands. Because the database is shared by all users of the interface, some commands (FLUSHALL for example) are disabled in it.
I am implementing an Express Web service using CouchBase as my database. To get all documents stored in a bucket, i created a view using the web console.
My question is if there is a way to do the same thing but without creating a view or using N1QL.
I was looking at the Couchbase Server REST API, but i didn't found a way.
Thank you
You could design your schema around something like this. I am thinking of a key pattern specifically that would allow for a bulk get of a range of docs.
Beyond that, there is no way without a view or N1QL.
In Couchbase 3.0 and higher, you can also use DCP to stream all documents from a bucket. Currently the DCP protocol is only implemented in java, you can see an example here: http://github.com/branor/couchbase-dcp-consumer
Note that there is a problem in the 1.1.0+ version of the couchbase core-io library, so you need to use version 1.1.0-dp (developer preview) to open a stream. DCP support in the SDK is still experimental, so I wouldn't use it in production yet.
Create a document that will hold the keys of all your documents.
While inserting a key value pair in couchbase, also append the key to that document.
Eg:
<Key1, Value1>
<Key2, Value2>
.
.
.
<Keyx, Valuex>
<All_Keys, <Key1, Key2, Key3...Keyx>>
To get all the documents,
Just do a client.get("All_Keys") and then do a client.getBulk() operation.
Let me explain in more detail:
1st: I'm running endeca 3.1, so Endeca Server here refers to 3.0's Data Domain.
I'm required to use an Endeca Server currently present on Endeca (Downloaded a Demo VM). All the info on it, including, groups, attributes and data, must be merged into out Endeca Server. (It can also be the other way around, i could merge my Endeca Server into this one.)
So far, i've tried to do the following:
1) Clone the Endeca Server
2) use the putCollection sconfig operation to create a collection on it with the same name i have on mine.
3) Load configurations using the LoadCollection & LoadAttributes graphs from OEID POC Template 3.1. I point to the new collection on the Configuration.xls file.
This is where i encounter an issue. The LoadAttributes graph gets a T/O message from the server's WS. Then the config WSDL becomes inaccesible for a while. I can't go beyond this point.
I've been able to load data into the collection, but i need to load the attributes first.
THanks in advance for your replies.
Regards
There are a few techniques.
Have you tried exporting the data domain and then importing it?
You can use the endeca-cmd tools to export to a file, and then import from that file. This would enable you to add 2 datastores into one server.
If you want to combine 2 datastores then that is a different question.
The simplest approach in 3.1 if the data collections are small. Extract then as CSV (via a data-table), convert to XLS and add them via self provisioning into separate collections within a single data store. If you are running in the VM this is potentially the easiest approach.
This can also be done using Integrator.
You don't need to load the attributes unless you are using multi-value types. You can call against the conversation web-service to extract data and then load it using 'bulk-load' I would not worry too much about creating the attributes unless this becomes essential due to their type or complexity. If you cannot call against the conversation web-service, then again extract as csv and load using Integrator.
I am trying to view my sagas in the RavenDB management studio, and loading even the initial page, all that I see is this "Querying documents..." box with a continuous moving progress bar. I can not seem to get past it, going from page to page it does not go away. Is there a way to pull all of the saga data into a list so I can look at it? It appears the issue is that the saga documents are continuously being added.
I've looked into the HTTP API and the Linq adapters, but I guess I am looking for something that already exists that can easily peer into the server much like the silverlight studio, except not such a pain. I more or less just want to pull a snapshot of all the documents into some kind of readable list.
I find LINQPad 4 convenient, the RavenDB driver for LINQPad can be found here:
https://github.com/ronnieoverby/RavenDB-Linqpad-Driver
For the command line - cURL using dynamic indexes as explained here:
http://ravendb.net/docs/http-api/indexes/dynamic-indexes
In the browser, go to http://localhost:8080/docs
You might need to install JsonView, but that should give you what you want.
If anyone wants to know how to browse the data through REST call,
"localhost:8080/databases/{database-name}/docs/{dataset-name}/id"
example:
"localhost:8080/databases/testDB/docs/Sites/1"
will give the json data for the "Sites" document
"localhost:8080/databases/testDB/docs/"
will give the json data for all the documents in
testDB.
