I wonder if there is any plan to support other languages beside Java. Since the storage store the values as an opaque bytestream, I think this is perfectly possible.
We have definitely considered this possibility and yes, it is feasible (after all, it's only software). There are several different approaches that can be used to implement this.
For now, I will say that it is perfectly reasonable to use JNI to talk to the KVStore API from other languages.
Just in case you are interested, I am learning/playing with some programming and Oracle NoSQL and wrote some very simple scripts in different languages (Jython, JRuby, Clojure, Groovy, Rhino, Java, Scala is under way) to access the database; they are under https://github.com/yeysus/14a. At the end, it all boils to Java though.
Thank you for you examples!
May you give some comment how use java example.
I compile this program on my machine and try start:
java -cp .:/opt/kv-1.2.123/lib/kvclient-1.2.123.jar Java_oraclenosql -h localhost -s kvstore -p 5000 -t ?What i must write here?
Hi. First you better navigate to the directory where the java file is, then you need to change the cp variable so it reflects where you have the kvclient-1.2.123.jar file in your machine. So it would look like
javac -cp .:/path/to/your/kvclient-1.2.123.jar Java_oraclenosql.java
Then you can execute it with
java -cp .:/opt/kv-1.2.123/lib/kvclient-1.2.123.jar Java_oraclenosql -s store_name -h host_name -p port -t
-t does not need any argument; it means it will run a test and output the results; it will sequentially count all records, put 1 new record, get the value of the same record, putIfAbsent a new record, putIfPresent the old record, iterate for a major key component, delete the 2 new records it created in between, and count all records again so you are sure your database was not contaminated by the test. I am adding a new argument, "operation", so the same functions can be called from the command line with values chosen by the user; this will be ready probably tomorrow.
I am also experimenting with some synchronization and some bioinformatics and a log file data import / export / analysis, but this will take some more days.
