Module hash_join

Structs

• HashValueWrapper 🔒
  The wrapper for JoinEntryState which should be Some most of the time in the hash table.
• InequalityKeyDesc 🔒
  Inequality key description for AsOf join.
• JoinEntryState
  We manages a HashMap in memory for all entries belonging to a join key. When evicted, cached does not hold any entries.
• JoinHashMap
• JoinHashMapMetrics
• JoinHashMapPostCommit
• TableInner

Enums

• CacheResult 🔒
• JoinEntryError

Functions

• fetch_degrees 🔒
  We use this to fetch ALL degrees into memory. We use this instead of a streaming interface. It is necessary because we must update the degree_state_table concurrently. If we obtain the degrees in a stream, we will need to hold an immutable reference to the state table for the entire lifetime, preventing us from concurrently updating the state table.
• into_stream 🔒
• update_degree 🔒

Type Aliases

• HashValueType
• InequalKeyType 🔒
• JoinHashMapInner 🔒
• PkType 🔒
  Memcomparable encoding.
