[jira] [Updated] (SOLR-13220) Allow jdbc Streaming Expression to
lazily cache connections
[ https://issues.apache.org/jira/browse/SOLR-13220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Cassandra Targett updated SOLR-13220:
-------------------------------------
Component/s: streaming expressions
> Allow jdbc Streaming Expression to lazily cache connections
> -----------------------------------------------------------
>
> Key: SOLR-13220
> URL: https://issues.apache.org/jira/browse/SOLR-13220
> Project: Solr
> Issue Type: New Feature
> Components: streaming expressions
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
> Fix For: 8.2
>
>
> The jdcb Streaming Expression currently opens and closes the database connection with each call. This hinders performance and scalability. This ticket will allow the jdbc stream to lazily cache the connection in a cache managed by the stream handler.
> The connectionUrl will be hashed to create a key to the cache. The connection will also be refreshed (closed/opened) periodically to ensure that they are not timed out during periods of inactivity.
