Islam AbdelRahman b88f8e87c5 Support SST files with Global sequence numbers [reland] ... Summary: reland https://reviews.facebook.net/D62523 - Update SstFileWriter to include a property for a global sequence number in the SST file `rocksdb.external_sst_file.global_seqno` - Update TableProperties to be aware of the offset of each property in the file - Update BlockBasedTableReader and Block to be able to honor the sequence number in `rocksdb.external_sst_file.global_seqno` property and use it to overwrite all sequence number in the file Something worth mentioning is that we don't update the seqno in the index block since and when doing a binary search, the reason for that is that it's guaranteed that SST files with global seqno will have only one user_key and each key will have seqno=0 encoded in it, This mean that this key is greater than any other key with seqno> 0. That mean that we can actually keep the current logic for these blocks Test Plan: unit tests Reviewers: sdong, yhchiang Subscribers: andrewkr, dhruba Differential Revision: https://reviews.facebook.net/D65211		8 years ago
