value_count(-Count)

Number of key-value pairs in the trie.

node_count(-Count)

Number of nodes in the trie.

size(-Bytes)

Required storage space of the trie.

compiled_size(-Bytes)

Required storage space for the compiled representation as used by trie_gen_compiled/2,3.

hashed(-Count)

Number of nodes that use a hashed index to its children.

lookup_count(-Count)

Number of trie_lookup/3 calls (only when compiled with O_TRIE_STATS).

gen_call_count(-Count)

Number of trie_gen/3 calls (only when compiled with O_TRIE_STATS).

wait(-Count)

Number of times a thread waited on this trie for another thread to complete it (shared tabling, only when compiled with O_TRIE_STATS).

deadlock(-Count)

Number of times this trie was part of a deadlock and its completion was abandoned (shared tabling, only when compiled with O_TRIE_STATS).

In addition, a number of additional properties are defined on answer tries.

invalidated(-Count)

Number of times the trie was invalidated (incremental tabling).

reevaluated(-Count)

Number of times the trie was re-evaluated (incremental tabling).

idg_affected_count(-Count)

Number of answer tries affected by this one (incremental tabling).

idg_dependent_count(-Count)

Number of answer tries this one depends on (incremental tabling).

idg_size(-Bytes)

Number of bytes in the IDG node representation.
