for us sessionId is not the actual key field. It will be something like some arbitrarystring+sessionid
and we will be running queries with - like "%sessionId%" to find all entries having a particular sessionid. In this case to improve performance can we apply any index ? is this approach better than running queries on value fields with PDX Serialization ? -- Sent from: http://apache-geode-incubating-developers-forum.70738.x6.nabble.com/
