8261e0026b Promote CompactionFilter* accessors to ColumnFamilyOptionsInterface (#3461)
Summary:
When adding CompactionFilter and CompactionFilterFactory settings to the Java layer, ColumnFamilyOptions was modified directly instead of ColumnFamilyOptionsInterface. This meant that the old-stye Options monolith was left behind.

This patch fixes that, by:
- promoting the CompactionFilter + CompactionFilterFactory setters from ColumnFamilyOptions -> ColumnFamilyOptionsInterface
- adding getters in ColumnFamilyOptionsInterface
- implementing setters in Options
- implementing getters in both ColumnFamilyOptions and Options
- adding testcases
- reusing a test CompactionFilterFactory by moving it to a common location

b878f93c70 Extend Transaction::GetForUpdate with do_validate (#4680)
Summary:
Transaction::GetForUpdate is extended with a do_validate parameter with default value of true. If false it skips validating the snapshot (if there is any) before doing the read. After the read it also returns the latest value (expects the ReadOptions::snapshot to be nullptr). This allows RocksDB applications to use GetForUpdate similarly to how InnoDB does. Similarly ::Merge, ::Put, ::Delete, and ::SingleDelete are extended with assume_exclusive_tracked with default value of false. It true it indicates that call is assumed to be after a ::GetForUpdate(do_validate=false).
The Java APIs are accordingly updated.

3a18bb3e15 BaseDeltaIterator: always check valid() before accessing key() (#4702)
Summary:
Current implementation of `current_over_upper_bound_` fails to take into consideration that keys might be invalid in either base iterator or delta iterator. Calling key() in such scenario will lead to assertion failure and runtime errors.
This PR addresses the bug by adding check for valid keys before calling `IsOverUpperBound()`, also added test coverage for iterate_upper_bound usage in BaseDeltaIterator
Also recommit https://github.com/facebook/rocksdb/pull/4656 (It was reverted earlier due to bugs)

Summary:
Added back `NO_ITERATORS` and moved `NO_ITERATOR_CREATED` to the end of `toCppTickers`.

This is a leftover fix which is needed in addition to a138e351bc to correctly convert java tickers to c++ tickers. a138e351bc only updated `toJavaTickerType` but both `toJavaTickerType` and `toCppTickers` need to be changed.

a138e351bc Fix compatibility of public ticker stats (#4701)
Summary:
- Added back the `NO_ITERATORS` that was removed in 5945e16dfc.
- Marked it as deprecated since it is no longer populated, but kept for API compatibility.
- Made sure the new tickers, `NO_ITERATOR_CREATED` and `NO_ITERATOR_DELETED`, are appended at the end of the enum, in case people are relying on the int values.

The change where `NO_ITERATOR_CREATED` and `NO_ITERATOR_DELETED` were introduced is unreleased so I believe it is ok to change their ordering.

5945e16dfc Divide NO_ITERATORS into two counters NO_ITERATOR_CREATED and NO_ITERATOR_DELETE (#4498)
Summary:
Currently, `Statistics` can record tick by `recordTick()` whose second parameter is an `uint64_t`.
That means tick can only increase.
If we want to reduce tick, we have to work around like `RecordTick(statistics_, NO_ITERATORS, uint64_t(-1));`.
That's kind of a hack.

So, this PR divide `NO_ITERATORS` into two counters `NO_ITERATOR_CREATED` and `NO_ITERATOR_DELETE`, making the counters increase only.

Fixes #3013 .

6ecd26af27 WriteBufferManager JNI fixes (#4579)
Summary:
1. `WriteBufferManager` should have a reference alive in Java side through `Options`/`DBOptions` otherwise, if it's GC'ed at java side, native side can seg fault.
2. native method `setWriteBufferManager()` in `DBOptions.java` doesn't have it's jni method invocation in rocksdbjni which is added in this PR
3. `DBOptionsTest.java` is referencing object of `Options`. Instead it should be testing against `DBOptions`. Seems like a copy paste error.
4. Add a getter for WriteBufferManager.

c7cf981a85 Add CompactRangeOptions for Java (#4220)
Summary:
Closes https://github.com/facebook/rocksdb/issues/4195

CompactRangeOptions are available the CPP API, but not in the Java API. This PR adds CompactRangeOptions to the Java API and adds an overloaded compactRange() method. See https://github.com/facebook/rocksdb/issues/4195 for the original discussion.

This change supports all fields of CompactRangeOptions, including the required enum converters in the JNI portal.

Significant changes:
- Make CompactRangeOptions available in the compactRange() for Java.
- Deprecate other compactRange() methods that have individual option params, like in the CPP code.
- Migrate rocksdb_compactrange_helper() to  CompactRangeOptions.
- Add Java unit tests for CompactRangeOptions.

b9846370e9 WriteUnPrepared: Add support for recovering WriteUnprepared transactions (#4078)
Summary:
This adds support for recovering WriteUnprepared transactions through the following changes:
- The information in `RecoveredTransaction` is extended so that it can reference multiple batches.
- `MarkBeginPrepare` is extended with a bool indicating whether it is an unprepared begin, and this is passed down to `InsertRecoveredTransaction` to indicate whether the current transaction is prepared or not.
- `WriteUnpreparedTxnDB::Initialize` is overridden so that it will rollback unprepared transactions from the recovered transactions. This can be done without updating the prepare heap/commit map, because this is before the DB has finished initializing, and after writing the rollback batch, those data structures should not contain information about the rolled back transaction anyway.

Commit/Rollback of live transactions is still unimplemented and will come later.

d5585bb605 Shared block cache in RocksJava
Summary:
Changes to support sharing block cache using the Java API.

Previously DB instances could share the block cache only when the same Options instance is passed to all the DB instances. But now, with this change, it is possible to explicitly create a cache and pass it to multiple options instances, to share the block cache.

Implementing this for [Rocksandra](https://github.com/instagram/cassandra/tree/rocks_3.0), but this feature has been requested by many java api users over the years.

c5302a8a58 Java wrapper for Native Comparators
Summary:
This is an abstraction for working with custom Comparators implemented in native C++ code from Java. Native code must directly extend `rocksdb::Comparator`. When the native code comparator is compiled into the RocksDB codebase, you can then create a Java Class, and JNI stub to wrap it.

Useful if the C++/JNI barrier overhead is too much for your applications comparator performance.

An example is provided in `java/rocksjni/native_comparator_wrapper_test.cc` and `java/src/main/java/org/rocksdb/NativeComparatorWrapperTest.java`.

- Options
- DBOptions

along with unit tests to assert the copy worked.

NOTE: Unit tests are failing in travis but it looks like a global timeout issue. These tests pass.
