[jira] [Updated] (IGNITE-16961) SQL API: Add prepared statement support.

     [ https://issues.apache.org/jira/browse/IGNITE-16961?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Yury Gerzhedovich updated IGNITE-16961:
---------------------------------------
    Description: 
Let's add prepared statement support.
 * avoid extra sending query parameters (incl. query text) after server-side statement object has been created (unless client re-connect happened)
 * avoid query planing more than once (unless client re-connect happened or schema has been changed).
 * avoid extra sending of query fragment plan (separate cache for fragments).
 * release server resources when statement was closed or session was invalidated.
