9674c11d01
Summary: Contains the following changes: - Implementation of cuckoo_table_factory - Adding cuckoo table into AdaptiveTableFactory - Adding cuckoo_table_db_test, similar to lines of plain_table_db_test - Minor fixes to Reader: When a key is found in the table, return the key found instead of the search key. - Minor fixes to Builder: Add table properties that are required by Version::UpdateTemporaryStats() during Get operation. Don't define curr_node as a reference variable as the memory locations may get reassigned during tree.push_back operation, leading to invalid memory access. Test Plan: cuckoo_table_reader_test --enable_perf cuckoo_table_builder_test cuckoo_table_db_test make check all make valgrind_check make asan_check Reviewers: sdong, igor, yhchiang, ljin Reviewed By: ljin Subscribers: leveldb Differential Revision: https://reviews.facebook.net/D21219
