Re: Adding index for Like operartor

Thank you Jason. I have one more question related to this. I have two options / object structures for storing and retrieving objects. First one . Storing objects like : {key :"ConstantString_randomString", List objects} and then use queries with like "ConstantString_%" where function index is

Adding index for Like operartor

Hi, I would like to add an index to key (keyindex) and the query executed is going to be like "constantstring%" where constant string is going to be the constant prefix in a lile query. In this case can we just go ahead with key index or should we use a function index ? key indexes are not

Store objects as List vs running queries and PutAll

I have a question regaring the performance metrics of putAll vs storing objects directly as List. which would be more performant 1. store object of the form { key1, {sessionId, List}} 2. store each message object in a list with unique key {key, sessionid, data} and then use putall for st

PuAll vs List

1.which is more performant - aggregating on client side and storing objects as a list and retrieving the whole object as an a list or 2. storing objects using putAll and running queries to get the objects. -- Sent from: http://apache-geode-incubating-developers-forum.70738.x6.nabble.com/

Re: Queries on key fields

Jason, how can we use both together, isnt it redundant as both serve the same purpose ? making retrieval faster ? -- Sent from: http://apache-geode-incubating-developers-forum.70738.x6.nabble.com/
