Reference doc
API reference
The following table outlines the API packages and reference docs for Pulsar Java clients.
| Package | Description | Maven Artifact |
|---|---|---|
| org.apache.pulsar.client.api | Java client API. See Client API overview for more reference. | org.apache.pulsar:pulsar-client:3.1.1 |
| org.apache.pulsar.client.admin | Java admin API. See Admin API overview for more reference. | org.apache.pulsar:pulsar-client-admin:3.1.1 |
org.apache.pulsar.client.all | Include both pulsar-client and pulsar-client-admin.Both pulsar-client and pulsar-client-admin are independently shaded packages. Consequently, the applications using both pulsar-client and pulsar-client-admin have redundant shaded classes. It would be troublesome if you introduce new dependencies but forget to update shading rules.In this case, you can use pulsar-client-all, which shades dependencies only one time and reduces the size of dependencies. | org.apache.pulsar:pulsar-client-all:3.1.1 |
