------------------------------
Hey [~criccomini], I will add a patch to the ticket as well. As per the build,
that's weird, I don't see it the repository as well, but a quick google search
shows me that those options did exist.
https://github.com/vpallabs/vpal/blob/master/src/rocksdb/java/RocksDBSample.java
{code}
Filter filter = new BloomFilter(10);
options.setCreateIfMissing(true)
.createStatistics()
.setWriteBufferSize(8 * SizeUnit.KB)
.setMaxWriteBufferNumber(3)
.setDisableSeekCompaction(true)
.setBlockSize(64 * SizeUnit.KB)
.setMaxBackgroundCompactions(10)
.setFilter(filter);
Statistics stats = options.statisticsPtr();
assert(options.createIfMissing() == true);
assert(options.writeBufferSize() == 8 * SizeUnit.KB);
assert(options.maxWriteBufferNumber() == 3);
assert(options.disableSeekCompaction() == true);
assert(options.blockSize() == 64 * SizeUnit.KB);
assert(options.maxBackgroundCompactions() == 10);
{code}
Let me check if they have changed anything in the master.
> Switch samza-kv to use RocksDB

> Key: SAMZA-236
> URL: https://issues.apache.org/jira/browse/SAMZA-236
> Project: Samza
> Issue Type: Bug
> Components: kv
> Affects Versions: 0.6.0
> Reporter: Chris Riccomini
> Assignee: Naveen
> Fix For: 0.8.0
>
>
> The samza-kv implementation is currently using LevelDB. RocksDB seems to have
> a number of interesting options that would be useful to Samza:
> # Ability to swap out skip list for a faster implementation when restoring
> data from a changelog stream.
> # Ability to disable compaction during changelog stream restoration.
> # Ability to have a single level (or single SST) rather than multiple levels
> in order to reduce read amplification.
> # A merge operation for doing lazy read-modify-write during compaction.
> And a lot more.
