After the rework in ~~DBZ-8860~~, it seems there is a small performance regression with adding new transactions to the cache:

Benchmark                                          Mode  Cnt   Score   Error   Units
MemoryTransactionCachePerfTest.addEventNew        thrpt   10  22.286 ± 1.950  ops/us
MemoryTransactionCachePerfTest.addEventOld        thrpt   10  14.831 ± 2.588  ops/us
MemoryTransactionCachePerfTest.addTransactionNew  thrpt   10   4.020 ± 0.625  ops/us
MemoryTransactionCachePerfTest.addTransactionOld  thrpt   10   8.417 ± 2.096  ops/us

With the new changes I proposed in the attached PR, performance is now:

Benchmark                                          Mode  Cnt   Score   Error   Units
MemoryTransactionCachePerfTest.addEventNew        thrpt   10  21.440 ± 2.633  ops/us
MemoryTransactionCachePerfTest.addEventOld        thrpt   10  14.707 ± 2.544  ops/us
MemoryTransactionCachePerfTest.addTransactionNew  thrpt   10   8.388 ± 1.420  ops/us
MemoryTransactionCachePerfTest.addTransactionOld  thrpt   10   8.393 ± 1.863  ops/us
