->tx-eidclj
(->tx-eid tx-foo)Takes a tx-num or tx-eid and returns the equivalent tx-eid
Takes a tx-num or tx-eid and returns the equivalent tx-eid
->tx-numclj

Takes a tx-num or tx-eid and returns the equivalent tx-num
allocate-temp-idclj
(allocate-temp-id)Allocates and returns a new temporary id.
If we are in a peer context, will count down from :cur-n. If we are in a transactor context, will count up from :tx-n.
Context is determined by the existence of the :tx-n key

pack-entity-idclj
(pack-entity-id op packed-id)(pack-entity-id p e retracted temp)A packed entity ID is 64 bits in the shape: [1 1 20 42 ].
The first bit is a temp-id flag The next bit is an added / removed flag The next 20 are the partition id The next 42 are the entity id
Arguments: p = partition-id e = entity-id retracted = true if entity is retracted temp = true if entity-id is temporary

set-max-allocated-id!clj
(set-max-allocated-id! max-id prev-tx-eid)resets the max allocated id to the passed value. NOTE: also resets the perm-id mapping
