Hui Xiao 9daf07305c Replace TableProperties::properties_offsets map with external_sst_file_global_seqno_offset (#9212) ... Summary: **Context:** Searching `TableProperties::properties_offsets` across the codebase reveals that internally it is only used to find the external SST file's global seqno offeset. Therefore we can narrow it down and replace this map property with a uint64_t property `external_sst_file_global_seqno_offset` to save memory usage related to table properties. Note: - See PR comments for discussion about potential impact on existing external usage of `TableProperties::properties_offsets` - See PR comments for discussion on keeping external SST file global seqno's offset VS using a simple flag indicating seqno's existence. **Summary:** - Replaced `TableProperties::properties_offsets` with `TableProperties::external_sst_file_global_seqno_offset` Pull Request resolved: https://github.com/facebook/rocksdb/pull/9212 Test Plan: - Relied on existing tests should be sufficient since `TableProperties::properties_offsets` existed before and should already be tested.
