pulsar release 默认是以容器为先，输出的日志都是console模式，以standalone为例，默认启动命令内容如下： [root@140 ~]# ps -ef|grep java root 6573 6409 99 21:15 pts/0 00:07:16 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-1.el7_9.x86_64/bin/java -Dlog4j.shutdownHookEnabled=false -cp

批量 pulsar 的批量发送与rocketmq不同，本质是client 进行缓存，根据producer创建参数自行进行控制，没有显示batch发送操作，示意代码如下： Producer<byte[]> BatchProducer = client.newProducer().topic("mybatch-topic").batchingMaxMessages(10) .batchingMaxPublishDelay(10, TimeUnit.MINUTES).sendTimeout(1

pulsar为防止netty等版本冲突，使用maven-shade-plugin（可以参考https://blog.youkuaiyun.com/yangguosb/article/details/80619481）进行了转换， 转换包的列表可以/pulsar-client/pom.xml <plugin> <!-- Shade all the dependencies to avoid conflicts --> <groupId>org.apach

清单如下： echo “Environment Vars for bookie:” echo “” echo " [metadata service]" echo " BK_zkServers is $BK_zkServers" echo " BK_CLUSTER_ROOT_PATH is $BK_CLUSTER_ROOT_PATH" echo " BK_metadataServiceUri is $BK_metadataServiceUri" echo “” echo " [bookie]" e

bookkeeper metadata 可以通过zk查看，如下： [zk: localhost:2181(CONNECTED) 9] ls /ledgers/00/0000 [L0121, L0144, L1361, L1436, L1443, L1486, L1492, L1496, L1518, L1528, L1531] [zk: localhost:2181(CONNECTED) 10] ls /ledgers/00/0000/L1361 [] [zk: localhost:2181(CONNECT
