## Main features
- Horizontally scalable (Millions of independent topics and millions
of messages published per second)
- Strong ordering and consistency guarantees
- Low latency durable storage
- Topic and queue semantics
- Load balancer
- Designed for being deployed as a hosted service:
- Multi-tenant
- Authentication
- Authorization
- Quotas
- Support mixing very different workloads
- Optional hardware isolation
- Keeps track of consumer cursor position
- REST API for provisioning, admin and stats
- Geo replication
- Transparent handling of partitioned topics
- Transparent batching of messages

## Build Pulsar
### Requirements
- JDK
| Pulsar Version | JDK Version |
|-------------------|:-------------------------------------------------:|
| master and 2.11 + | [JDK 17](https://adoptium.net/?variant=openjdk17) |
| 2.8 / 2.9 / 2.10 | [JDK 11](https://adoptium.net/?variant=openjdk11) |
| 2.7 - | [JDK 8](https://adoptium.net/?variant=openjdk8) |
- Maven 3.6.1+
- zip
> **Note**:
>
> This project includes a [Maven Wrapper](https://maven.apache.org/wrapper/) that can be used instead of a system-installed Maven.
> Use it by replacing `mvn` by `./mvnw` on Linux and `mvnw.cmd` on Windows in the commands below.
>
> It's better to use CMD rather than Powershell on Windows. Because maven will activate the `windows` profile which runs `rename-netty-native-libs.cmd`.
### Build
Compile and install:
```bash
$ mvn install -DskipTests
```
Compile and install individual module
```bash
$ mvn -pl module-name (e.g: pulsar-broker) install -DskipTests
```
### Minimal build (This skips most of external connectors and tiered storage handlers)
```bash
mvn install -Pcore-modules,-main -DskipTests
```
Run Unit Tests:
```bash
$ mvn test
```
Run Individual Unit Test:
```bash
$ mvn -pl module-name (e.g: pulsar-client) test -Dtest=unit-test-name (e.g: ConsumerBuilderImplTest)
```
Run Selected Test packages:
```bash
$ mvn test -pl module-name (for example, pulsar-broker) -Dinclude=org/apache/pulsar/**/*.java
```
Start standalone Pulsar service:
```bash
$ bin/pulsar standalone
```
Check https://pulsar.apache.org for documentation and examples.
## Build custom docker images
* Docker images must be built with Java 8 for `branch-2.7` or previous branches because of [ISSUE-8445](https://github.com/apache/pulsar/issues/8445).
* Java 11 is the recommended JDK version in `branch-2.8`, `branch-2.9` and `branch-2.10`.
* Java 17 is the recommended JDK version in `master`.
The following command builds the docker images `apachepulsar/pulsar-all:latest` and `apachepulsar/pulsar:latest`:
```bash
mvn clean install -DskipTests
mvn package -Pdocker,-main -am -pl docker/pulsar-all -DskipTests
```
After the images are built, they can be tagged and pushed to your custom repository. Here's an example of a bash script that tags the docker images with the current version and git revision and pushes them to `localhost:32000/apachepulsar`.
```bash
image_repo_and_project=localhost:32000/apachepulsar
pulsar_version=$(mvn initialize help:evaluate -Dexpression=project.version -pl . -q -DforceStdout)
gitrev=$(git rev-parse HEAD | colrm 10)
tag="${pulsar_version}-${gitrev}"
echo "Using tag $tag"
docker tag apachepulsar/pulsar-all:latest ${image_repo_and_project}/pulsar-all:$tag
docker push ${image_repo_and_project}/pulsar-all:$tag
docker tag apachepulsar/pulsar:latest ${image_repo_and_project}/pulsar:$tag
docker push ${image_repo_and_project}/pulsar:$tag
```
