# HostProviderFactory: New factory class that checks connection strings and
instantiates appropriate HostProvider

> Key: ZOOKEEPER-4982
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4982
> Project: ZooKeeper
> Issue Type: New Feature
> Components: java client
> Reporter: Li Wang
> Priority: Major
> Fix For: 3.10.0
>
>
> Enhance ZooKeeper Java client to automatically detect connection string
> format and select appropriate HostProvider, enabling zero-code-change
> migration from static to DNS SRV-based service discovery.
> Following ZOOKEEPER-4956, applications must explicitly choose between
> StaticHostProvider and DnsSrvHostProvider. This ticket enables automatic
> provider selection based on connection string format, allowing seamless
> migration without code changes.
