# LevelDB JNI |
||||||
|
|
||||||
|
## Description |
||||||
|
|
||||||
|
LevelDB JNI gives you a Java interface to the |
||||||
|
[LevelDB](http://code.google.com/p/leveldb/) C++ library |
||||||
|
which is a fast key-value storage library written at Google |
||||||
|
that provides an ordered mapping from string keys to string values.. |
||||||
|
|
||||||
|
|
||||||
|
## Using as a Maven Dependency |
||||||
|
|
||||||
|
You just nee to add the following repositories and dependencies to your Maven pom. |
||||||
|
|
||||||
|
<repositories> |
||||||
|
<repository> |
||||||
|
<id>fusesource.nexus.snapshot</id> |
||||||
|
<name>FuseSource Community Snapshot Repository</name> |
||||||
|
<url>http://repo.fusesource.com/nexus/content/groups/public-snapshots</url> |
||||||
|
</repository> |
||||||
|
</repositories> |
||||||
|
|
||||||
|
<dependencies> |
||||||
|
<dependency> |
||||||
|
<groupId>org.fusesource.leveldbjni</groupId> |
||||||
|
<artifactId>leveldbjni-all</artifactId> |
||||||
|
<version>1.1</version> |
||||||
|
</dependency> |
||||||
|
</dependencies> |
||||||
|
|
||||||
|
## API Usage: |
||||||
|
|
||||||
|
Recommended Package imports: |
||||||
|
|
||||||
|
import org.iq80.leveldb.*; |
||||||
|
import static org.fusesource.leveldbjni.JniDBFactory.*; |
||||||
|
import java.io.*; |
||||||
|
|
||||||
|
Opening and closing the database. |
||||||
|
|
||||||
|
Options options = new Options(); |
||||||
|
options.createIfMissing(true); |
||||||
|
DB db = factory.open(new File("example"), options); |
||||||
|
try { |
||||||
|
// Use the db in here.... |
||||||
|
} finally { |
||||||
|
// Make sure you close the db to shutdown the |
||||||
|
// database and avoid resource leaks. |
||||||
|
db.close(); |
||||||
|
} |
||||||
|
|
||||||
|
Putting, Getting, and Deleting key/values. |
||||||
|
|
||||||
|
db.put(bytes("Tampa"), bytes("rocks")); |
||||||
|
String value = asString(db.get(bytes("Tampa"))); |
||||||
|
db.delete(wo, bytes("Tampa")); |
||||||
|
|
||||||
|
Performing Batch/Bulk/Atomic Updates. |
||||||
|
|
||||||
|
WriteBatch batch = db.createWriteBatch(); |
||||||
|
try { |
||||||
|
batch.delete(bytes("Denver")); |
||||||
|
batch.put(bytes("Tampa"), bytes("green")); |
||||||
|
batch.put(bytes("London"), bytes("red")); |
||||||
|
|
||||||
|
db.write(batch); |
||||||
|
} finally { |
||||||
|
// Make sure you close the batch to avoid resource leaks. |
||||||
|
batch.close(); |
||||||
|
} |
||||||
|
|
||||||
|
Iterating key/values. |
||||||
|
|
||||||
|
DBIterator iterator = db.iterator(); |
||||||
|
try { |
||||||
|
for(iterator.seekToFirst(); iterator.hasNext(); iterator.next()) { |
||||||
|
String key = asString(iterator.peekNext().getKey()); |
||||||
|
String value = asString(iterator.peekNext().getValue()); |
||||||
|
System.out.println(key+" = "+value); |
||||||
|
} |
||||||
|
} finally { |
||||||
|
// Make sure you close the iterator to avoid resource leaks. |
||||||
|
iterator.close(); |
||||||
|
} |
||||||
|
|
||||||
|
Working against a Snapshot view of the Database. |
||||||
|
|
||||||
|
ReadOptions ro = new ReadOptions(); |
||||||
|
ro.snapshot(db.getSnapshot()); |
||||||
|
try { |
||||||
|
|
||||||
|
// All read operations will now use the same |
||||||
|
// consistent view of the data. |
||||||
|
... = db.iterator(ro); |
||||||
|
... = db.get(bytes("Tampa"), ro); |
||||||
|
|
||||||
|
} finally { |
||||||
|
// Make sure you close the snapshot to avoid resource leaks. |
||||||
|
ro.snapshot().close(); |
||||||
|
} |
||||||
|
|
||||||
|
Using a custom Comparator. |
||||||
|
|
||||||
|
DBComparator comparator = new DBComparator(){ |
||||||
|
public int compare(byte[] key1, byte[] key2) { |
||||||
|
return new String(key1).compareTo(new String(key2)); |
||||||
|
} |
||||||
|
public String name() { |
||||||
|
return "simple"; |
||||||
|
} |
||||||
|
public byte[] findShortestSeparator(byte[] start, byte[] limit) { |
||||||
|
return start; |

||||||
|
|

Using a memory pool to make native memory allocations more efficient: |
||||||
|
|
||||||
|
JniDBFactory.pushMemoryPool(1024 * 512); |
||||||
|
try { |
||||||
|
// .. work with the DB in here, |
||||||
|
} finally { |
||||||
|
JniDBFactory.popMemoryPool(); |
||||||
|
} |
||||||
|
|
||||||
|
## Building |
||||||
|
|
||||||
|
### Prerequisites |
||||||
|
|
||||||
|
* GNU compiler toolchain |
||||||
|
* [Maven 3](http://maven.apache.org/download.html) |
||||||
|
|
||||||
|
### Supported Platforms |
||||||
|
|
||||||
|
The following worked for me on: |
||||||
|
|
||||||
|
* OS X Lion with X Code 4 |
||||||
|
* CentOS 5.6 (32 and 64 bit) |
||||||
|
* Ubuntu 12.04 (32 and 64 bit) |
||||||
|
* apt-get install autoconf libtool |
||||||
|
|
||||||
|
### Build Procedure |
||||||
|
|
||||||
|
Then download the snappy, leveldb, and leveldbjni project source code: |
||||||
|
|
||||||
|
wget http://snappy.googlecode.com/files/snappy-1.0.5.tar.gz |
||||||
|
tar -zxvf snappy-1.0.5.tar.gz |
||||||
|
git clone git://github.com/chirino/leveldb.git |
||||||
|
git clone git://github.com/fusesource/leveldbjni.git |
||||||
|
export SNAPPY_HOME=`cd snappy-1.0.5; pwd` |
||||||
|
export LEVELDB_HOME=`cd leveldb; pwd` |
||||||
|
export LEVELDBJNI_HOME=`cd leveldbjni; pwd` |
||||||
|
|
||||||
|
Compile the snappy project. This produces a static library. |
||||||
|
|
||||||
|
cd ${SNAPPY_HOME} |
||||||
|
./configure --disable-shared --with-pic |
||||||
|
make |
||||||
|
|
||||||
|
Patch and Compile the leveldb project. This produces a static library. |
||||||
|
|
||||||
|
cd ${LEVELDB_HOME} |
||||||
|
export LIBRARY_PATH=${SNAPPY_HOME} |
||||||
|
export C_INCLUDE_PATH=${LIBRARY_PATH} |
||||||
|
export CPLUS_INCLUDE_PATH=${LIBRARY_PATH} |
||||||
|
git apply ../leveldbjni/leveldb.patch |
||||||
|
make libleveldb.a |
||||||
|
|
||||||
|
Now use maven to build the leveldbjni project. |
||||||
|
|
||||||
|
cd ${LEVELDBJNI_HOME} |
||||||
|
mvn clean install -P download -P ${platform} |
||||||
|
|
||||||
|
Replace ${platform} with one of the following platform identifiers (depending on the platform your building on): |
||||||
|
|
||||||
|
* osx |
||||||
|
* linux32 |
||||||
|
* linux64 |
||||||
|
* win32 |
||||||
|
* win64 |
||||||
|
|
||||||
|
If your platform does not have the right auto-tools levels available |
||||||
|
just copy the `leveldbjni-${version}-SNAPSHOT-native-src.zip` artifact |
||||||
|
from a platform the does have the tools available then add the |
||||||
|
following argument to your maven build: |
||||||
|
|
||||||
|
-Dnative-src-url=file:leveldbjni-${verision}-SNAPSHOT-native-src.zip |
||||||
|
|
||||||
|
### Build Results |
||||||
|
|
||||||
|
* `leveldbjni/target/leveldbjni-${version}.jar` : The java class file to the library. |
||||||
|
* `leveldbjni/target/leveldbjni-${version}-native-src.zip` : A GNU style source project which you can use to build the native library on other systems. |
||||||
|
* `leveldbjni-${platform}/target/leveldbjni-${platform}-${version}.jar` : A jar file containing the built native library using your currently platform. |

# How To Release |
||||||
|
|
||||||
|
Since levedbjni has to be build against multiple platforms, the standard maven release plugin will not work to do the release. |
||||||
|
|
||||||
|
Once you ready to do the release, create a branch for the release using: |
||||||
|
|
||||||
|
git co -b ${version}.x |
||||||
|
|
||||||
|
Update the version number in the poms using: |
||||||
|
|
||||||
|
mvn -P all org.codehaus.mojo:versions-maven-plugin:1.2:set org.codehaus.mojo:versions-maven-plugin:1.2:commit -DnewVersion="${version}" |
||||||
|
git commit -am "Preping for a the ${version} release" |
||||||
|
git tag "leveldbjni-${version}" |
||||||
|
git push origin "leveldbjni-${version}" |
||||||
|
|
||||||
|
Now release the non-platform specific artifacts using: |
||||||
|
|
||||||
|
mvn clean deploy -P release -P download |
||||||
|
|
||||||
|
Then for each platform, shell into the box check out the "leveldbjni-${version}" tag and then: |
||||||
|
|
||||||
|
cd $platform |
||||||
|
mvn clean deploy -Dleveldb=`cd ../../leveldb; pwd` -Dsnappy=`cd ../../snappy-1.0.3; pwd` -P release -P download |
||||||
|
|
||||||
|
Finally release the `leveldbjni-all` which uber jars all the previously released artifacts. |
||||||
|
|
||||||
|
cd leveldbjni-all |
||||||
|
mvn clean deploy -P release -P download |
||||||
|
|
||||||
|
Congrats your done. Make sure your releasing the artifacts in Nexus after each step. |
