Lokesh Khurana commented on PHOENIX-6523:
-----------------------------------------
[~stoty] we are pushing 5.2 client to production and while doing so we are
seeing regression in queries. It is coming from PhoenixDriver.connect() call
and after further debugging we saw that this Jira made changes where for every
connect call we are creating [new
ConnectionInfo|https://github.com/apache/phoenix/blob/5.2/phoenix-core-client/src/main/java/org/apache/phoenix/jdbc/PhoenixDriver.java#L254]
and that is creating new [Configuration every
time|https://github.com/apache/phoenix/blob/070380d64e44535174565eeb0a71c1da8fb4b650/phoenix-core-client/src/main/java/org/apache/phoenix/jdbc/ConnectionInfo.java#L113C30-L113C95]

> Support for HBase Registry Implementations through Phoenix connection URL
> -------------------------------------------------------------------------
>
> Key: PHOENIX-6523
> URL: https://issues.apache.org/jira/browse/PHOENIX-6523
> Project: Phoenix
> Issue Type: Improvement
> Components: core
> Reporter: Ramie Raufdeen
> Assignee: Istvan Toth
> Priority: Major
> Fix For: 5.2.0, 5.1.4
>
>
> https://issues.apache.org/jira/browse/HBASE-23305
> https://issues.apache.org/jira/browse/HBASE-18095
>
> HBase now supports a zookeeper-less connection strategy using a Master
> Registry implementation.
>
> For this to work, the client simply needs to set a list of <host:port>s of
> the HMaster quorum
>
> {code:java}
> <property>
> <name>hbase.masters</name>
> <value>master1:16000,master2:16001,master3:16000</value>
> </property>
> {code}
>
> To support opting into this from a Phoenix connection URL, we can introduce a
> "connector type". We'll leverage the *+* char of [JDBC URL
> grammar|https://docs.oracle.com/cd/E17952_01/connector-j-8.0-en/connector-j-reference-jdbc-url-format.html]
> to specify the connection type. Connections will start to look something
> like this:
> {code:java}
> jdbc:phoenix+zk:hostname1,2,3...:<properties>
> jdbc:phoenix+hrpc:hostname1,2,3...:<properties>
> jdbc:phoenix+bigtable:hostname1,2,3...:<properties>{code}
> Above are examples of opting into hrpc/zk/bigtable registry implementations
> of HBase.
>
> If no connector is specified, the driver will default to a Zookeeper based
> connection.
>
