parReg.tx.PrTxQueryTest

public class PrTxQueryTest
extends Object

Prototype for High Priority Use Case #1 (PartitionedRegions only) - Concurrent tx on colocated entries (no conflict expected) - tx consists of new entry in Region_1 with updates to entries in Regions 2-4 - other threads query these regions (we should not see any updates without - being able to see ALL updates. This is a prototype for now which does the following: creates the 4 colocated regions (Region_1 -> Region_4) populates regions 2-4 with util/QueryObjects (extra.value = null) for both positive and negative counter values up to maxKeys reset the positive and negative counters to zero positiveTxThread creates an entry in Region_1 and updates the corresponding entries in Regions_2 through 4 by setting queryObject.extra.value = key negativeTxThread creates an entry in Region_1 and updates the corresponding entries in Regions_2 through 4 by setting queryObject.extra.value = key Problem is currently how to figure out if we can see all or nothing (when query is region specific. Will need to synchronize (waitForCounter) for threads to coordinate: - readyForTx (tx and query threads at sync point) - query threads wait for positive or negative sync point - Tx thread can then validate that all (or none) saw the new entry + updates
