dc9d70de65 Optimistic Transactions
Summary: Optimistic transactions supporting begin/commit/rollback semantics.  Currently relies on checking the memtable to determine if there are any collisions at commit time.  Not yet implemented would be a way of enuring the memtable has some minimum amount of history so that we won't fail to commit when the memtable is empty.  You should probably start with transaction.h to get an overview of what is currently supported.

Test Plan: Added a new test, but still need to look into stress testing.

c815351038 Support saving history in memtable_list
Summary:
For transactions, we are using the memtables to validate that there are no write conflicts.  But after flushing, we don't have any memtables, and transactions could fail to commit.  So we want to someone keep around some extra history to use for conflict checking.  In addition, we want to provide a way to increase the size of this history if too many transactions fail to commit.

After chatting with people, it seems like everyone prefers just using Memtables to store this history (instead of a separate history structure).  It seems like the best place for this is abstracted inside the memtable_list.  I decide to create a separate list in MemtableListVersion as using the same list complicated the flush/installalflushresults logic too much.

This diff adds a new parameter to control how much memtable history to keep around after flushing.  However, it sounds like people aren't too fond of adding new parameters.  So I am making the default size of flushed+not-flushed memtables be set to max_write_buffers.  This should not change the maximum amount of memory used, but make it more likely we're using closer the the limit.  (We are now postponing deleting flushed memtables until the max_write_buffer limit is reached).  So while we might use more memory on average, we are still obeying the limit set (and you could argue it's better to go ahead and use up memory now instead of waiting for a write stall to happen to test this limit).

However, if people are opposed to this default behavior, we can easily set it to 0 and require this parameter be set in order to use transactions.

Test Plan: Added a xfunc test to play around with setting different values of this parameter in all tests.  Added testing in memtablelist_test and planning on adding more testing here.

fd8804f979 [RocksJava] Expose MemEnv in RocksJava
Summary:
In 3.10 the C++ code was extended with a MemEnv implementation. This
is now also available in RocksJava.

Changes:
- Extraced abstract super class Env
- Introduced RocksMemEnv
- Remove unnecessary disposeInternal method. The disposal of the default environment is managed by C++ so there needs to be no disposeInternal method in Java.
- Introduced a RocksMemEnvTest, which is aligned with the C++ equivalent.

Test Plan:
make rocksdbjava
make jtest

5615e23d8c [RocksJava] 32-Bit adjustments
Summary:
Before this change overflowing size_t values led to a checked Exception.

After that change:

size_t overflows on 32-Bit architecture throw now an IllegalArgumentException,
which removes the necessity for a developer to catch these Exceptions explicitly.

This is especially an advantage for developers targeting 64-Bit systems because
it is not necessary anymore to catch exceptions which are never thrown on a 64-Bit
system.

57f2a00c6f RocksJava - JNI Logger callback
Summary:
Within this commit a new AbstractLogger was introduced
which allows to handle log messages at an application level.

Log messages are passed up to Java using a JNI callback.

This allows a Java-Developer to use common Java APIs for log
messages e.g. SLF4J, LOG4J, etc. Within this commit no new
dependencies were introduced, which keeps the RocksDB API clean
and doesn`t force a developer to use a predefined high-level Java API.

Another feature is to dynamically set a custom loggers verbosity at
runtime using its public method `setInfoLogLevel` and to retrieve
the currently active level using the `infoLogLevel` method.

Test Plan:
make clean jclean rocksdbjava jtest
mvn -f rocksjni.pom package
