Summary: Changing blob file format and some code cleanup around the change. The change with blob log format are: * Remove timestamp field in blob file header, blob file footer and blob records. The field is not being use and often confuse with expiration field. * Blob file header now come with column family id, which always equal to default column family id. It leaves room for future support of column family. * Compression field in blob file header now is a standalone byte (instead of compact encode with flags field) * Blob file footer now come with its own crc. * Key length now being uint64_t instead of uint32_t * Blob CRC now checksum both key and value (instead of value only). * Some reordering of the fields. The list of cleanups: * Better inline comments in blob_log_format.h * rename ttlrange_t and snrange_t to ExpirationRange and SequenceRange respectively. * simplify blob_db::Reader * Move crc checking logic to inside blob_log_format.cc Closes https://github.com/facebook/rocksdb/pull/3081 Differential Revision: D6171304 Pulled By: yiwu-arbug fbshipit-source-id: e4373e0d39264441b7e2fbd0caba93ddd99ea2af
