Class BatteryKVTransactionAlias

java.lang.Object

com.neocoretechs.rocksack.test.BatteryKVTransactionAlias

public class BatteryKVTransactionAlias
extends java.lang.Object

Transaction KV test battery with alias interleaved operations.

We will operate with 2 main transactions on 2 aliased databases. We will also toss in some operations on an intermediate transaction that will be rolled back and discarded.

The 2 main transactions will contain even and odd records. In one database it will represent the set of even records, in the other, the set of odd records. We will verify that on each occasion the transactions are faithfully maintained.

RockSack transactions are a bit more flexible and encompass a larger domain than RocksDb transactions, but still preserve the concepts of isolation, durability and atomicity. RockSack transactions can span multiple classes and databases. RocksSack transactions function as more of a container whose context can be defined as needed. NOTES: program argument is database tablespace i.e. C:/users/you/RockSack/ C:/users/you/RockSack should be valid path. C:/users/you/RockSack/ALIAS1java.lang.String, etc. will be created.

Use 2 different interleaved transactions to insert to the same database without conflict.

Parameters:

xid - Transaction 1

alias12 - database alias we are operating upon; we just use it as convenient data to help form the key

bmap3 - TransactionalMap linked to the alias

Throws:

java.lang.Exception

battery1AR6

public static void battery1AR6(TransactionId xid,
                               Alias alias12,
                               TransactionalMap bmap3,
                               int j)
                        throws java.lang.Exception

Test the higher level functions in the RelatrixKV. public Set entrySet() Returns a Set view of the mappings contained in this map. The set's iterator returns the entries in ascending key order. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations.

Parameters:

xid -

alias12 -

bmap3 -

j -

Throws:

java.lang.Exception
