Summary:
info_log from supplied Options can be nullptr. Using the one from
db_impl. Also call flush after that since no more loggging will happen

Summary:
Intead of passing callback function pointer and its arg on Table::Get()

2dc6f62bb9 handle kDelete type in cuckoo builder
Summary:
when I changed std::vector<std::string, std::string> to std::string to
store key/value pairs in builder, I missed the handling for kDeletion
type. As a result, value_size_ can be wrong if the first add key is for
deletion.

5340484266 Built-in comparator(s) in RocksJava
Extended Built-in comparators with ReverseBytewiseComparator.

Reverse key handling is under certain conditions essential. E.g. while
using timestamp versioned data.

As native-comparators were not available using JAVA-API. Both built-in comparators
were exposed via JNI to be set upon database creation time.

d439451fab delay initialization of cuckoo table iterator
Summary:
cuckoo table iterator creation is quite expensive since it needs to load
all data and sort them. After compaction, RocksDB creates a new iterator
of the new file to make sure it is in good state. That makes the DB
creation quite slow. Delay the iterator db sort to the seek time to
speed it up.

94997eab5e reduce memory usage of cuckoo table builder
Summary:
builder currently buffers all key value pairs as a vector of
pair<string, string>. That is too much due to std::string
overhead. It wasn't able to fit 1B key/values (12bytes total) in 100GB
of ram. Switch to use a plain string to store the key/value sequence and
use only 12GB of ram as a result.

c6275956e2 improve memory efficiency of cuckoo reader
Summary:
When creating a new iterator, instead of storing mapping from key to
bucket id for sorting, store only bucket id and read key from mmap file
based on the id. This reduces from 20 bytes per entry to only 4 bytes.

fbd2dafc9f CompactedDBImpl::MultiGet() for better CuckooTable performance
Summary:
Add the MultiGet API to allow prefetching.
With file size of 1.5G, I configured it to have 0.9 hash ratio that can
fill With 115M keys and result in 2 hash functions, the lookup QPS is
~4.9M/s  vs. 3M/s for Get().
It is tricky to set the parameters right. Since files size is determined
by power-of-two factor, that means # of keys is fixed in each file. With
big file size (thus smaller # of files), we will have more chance to
waste lot of space in the last file - lower space utilization as a
result. Using smaller file size can improve the situation, but that
harms lookup speed.

d0de413f4d WriteBatchWithIndex to allow different Comparators for different column families
Summary:
Previously, one single column family is given to WriteBatchWithIndex to index keys for all column families. An extra map from column family ID to comparator is maintained which can override the default comparator given in the constructor. A WriteBatchWithIndex::SetComparatorForCF() is added for user to add comparators per column family.

Also move more codes into anonymous namespace.

Summary: To avoid false positive test failures when the file system doesn't support fallocate.

Skip the test if the error code indicates it is not supported.
