-----------------------------------------
Summary: Add property to suggest index to use in
AuthorizableQueryManager
Key: OAK-12269
URL: https://issues.apache.org/jira/browse/OAK-12269
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Alejandro Moratinos
User/group searches built through
org.apache.jackrabbit.api.security.user.QueryBuilder (executed via
UserManager#findAuthorizables(Query)) are translated by UserQueryManager into
an XPath statement. The query engine then picks an index based on cost. There
is currently no way for a caller to influence which index is used for these
queries.
Oak already supports the \{{option(index tag <tag>)}} query option for
SQL2/XPath (see [query option index
tag|https://jackrabbit.apache.org/oak/docs/query/query-engine.html#query-option-index-tag]),
but the user-management query API does not expose it, so it cannot be applied
to authorizable searches.
h4. Proposed change
Add an index-tag hint to the user query API and propagate it into the generated
statement.
