VersionedCrdsValue.insert_timestamp is used for fetching crds values inserted since last query: https://github.com/solana-labs/solana/blob/ec37a843a/core/src/cluster_info.rs#L1197-L1215 https://github.com/solana-labs/solana/blob/ec37a843a/core/src/cluster_info.rs#L1274-L1298 So it is crucial that insert_timestamp does not go backward in time when new values are inserted into the table. However std::time::SystemTime is not monotonic, or due to workload, lock contention, thread scheduling, etc, ... new values may be inserted with a stalled timestamp way in the past. Additionally, reading system time for the above purpose is inefficient/unnecessary. This commit adds an ordinal index to crds values indicating their insert order. Additionally, it implements a new Cursor type for fetching values inserted since last query. |
