909 | ||
910 | Each PG slot includes queues for events that are processing and/or waiting | |
911 | for a PG to be materialized in the slot. | |
912 | ||
913 | These are the constraints: | |
914 | ||
f67539c2 | 915 | - client ops must remained ordered by client, regardless of std::map epoch |
11fdf7f2 TL |
916 | - peering messages/events from peers must remain ordered by peer |
917 | - peering messages and client ops need not be ordered relative to each other | |
918 | ||
919 | - some peering events can create a pg (e.g., notify) | |
920 | - the query peering event can proceed when a PG doesn't exist | |
921 | ||
922 | Implementation notes: | |
923 | ||
924 | - everybody waits for split. If the OSD has the parent PG it will instantiate | |
925 | the PGSlot early and mark it waiting_for_split. Everything will wait until | |
926 | the parent is able to commit the split operation and the child PG's are | |
927 | materialized in the child slots. | |
928 | ||
929 | - every event has an epoch property and will wait for the OSDShard to catch | |
930 | up to that epoch. For example, if we get a peering event from a future | |
931 | epoch, the event will wait in the slot until the local OSD has caught up. | |
932 | (We should be judicious in specifying the required epoch [by, e.g., setting | |
933 | it to the same_interval_since epoch] so that we don't wait for epochs that | |
934 | don't affect the given PG.) | |
935 | ||
936 | - we maintain two separate wait lists, *waiting* and *waiting_peering*. The | |
9f95a23c | 937 | OpSchedulerItem has an is_peering() bool to determine which we use. Waiting |
11fdf7f2 TL |
938 | peering events are queued up by epoch required. |
939 | ||
940 | - when we wake a PG slot (e.g., we finished split, or got a newer osdmap, or | |
941 | materialized the PG), we wake *all* waiting items. (This could be optimized, | |
942 | probably, but we don't bother.) We always requeue peering items ahead of | |
943 | client ops. | |
944 | ||
945 | - some peering events are marked !peering_requires_pg (PGQuery). if we do | |
946 | not have a PG these are processed immediately (under the shard lock). | |
947 | ||
948 | - we do not have a PG present, we check if the slot maps to the current host. | |
949 | if so, we either queue the item and wait for the PG to materialize, or | |
950 | (if the event is a pg creating event like PGNotify), we materialize the PG. | |
951 | ||
952 | - when we advance the osdmap on the OSDShard, we scan pg slots and | |
953 | discard any slots with no pg (and not waiting_for_split) that no | |
f67539c2 | 954 | longer std::map to the current host. |
