Igor Canadi 72918efffe [column families] Implement DB::OpenWithColumnFamilies() ... Summary: In addition to implementing OpenWithColumnFamilies, this diff also includes some minor changes: * Changed all column family names from Slice() to std::string. The performance of column family name handling is not critical, and it's more convenient and cleaner to have names as std::strings * Implemented ColumnFamilyOptions(const Options&) and DBOptions(const Options&) * Added ColumnFamilyOptions to VersionSet::ColumnFamilyData. ColumnFamilyOptions are specified on OpenWithColumnFamilies() and CreateColumnFamily() I will keep the diff in the Phabricator for a day or two and will push to the branch then. Feel free to comment even after the diff has been pushed. Test Plan: Added a simple unit test Reviewers: dhruba, haobo CC: leveldb Differential Revision: https://reviews.facebook.net/D15033		2014-01-07 11:05:50 -08:00
