Module keys 

Structs

BudgetKeyContext

Key context for budget partition keys.

ExecKeyContext

Pre-computed key context for all keys on an execution’s partition. Created once per operation and reused for all key construction.

FlowIndexKeys

Flow-partition index keys.

FlowKeyContext

Key context for flow-structural partition keys.

IndexKeys

Index keys scoped to a single execution partition.

QuotaKeyContext

Key context for quota partition keys.

Constants

USAGE_DEDUP_KEY_PREFIX

Shared prefix for the usage-dedup keyspace. Must match the ff:usagededup: literal referenced in lua/**.lua (notably lua/budget.lua:99, the ff_report_usage_and_check function). Grep ff:usagededup: to find all producers, consumers, and test fixtures in one search.

Functions

budget_attach_key

Budget attachment key (not budget-ID scoped).

budget_policies_index

Budget policies index — SET of budget IDs on this partition. Used by the budget reconciler for cluster-safe discovery (replaces SCAN).

budget_resets_key

Budget reset schedule index.

global_config_partitions

Partition configuration — ff:config:partitions (§8.3). Validated on startup; created on first boot.

idempotency_key

ff:idem:{p:N}:<namespace>:<idempotency_key>

lane_config_key

Lane configuration key.

lane_counts_key

Lane counts key.

lanes_index_key

Lane registry.

namespace_executions_key

ff:ns:<namespace>:executions

noop_key

Placeholder key that shares a hash tag with other KEYS in the same FCALL.

quota_attach_key

Quota attachment key.

quota_policies_index

Quota policy index — SET of policy IDs on this partition. Used by the quota reconciler for cluster-safe discovery (replaces SCAN).

tag_index_key

ff:tag:<namespace>:<key>:<value>

usage_dedup_key

Build a usage-dedup key: ff:usagededup:<hash_tag>:<dedup_id>.

waitpoint_key_resolution

Waitpoint key resolution — ff:wpkey:{p:N}:<waitpoint_key>

worker_caps_key

Non-authoritative capability advertisement STRING for a worker (sorted CSV). Written by ff-sdk::FlowFabricWorker::connect, read by the engine’s unblock scanner to decide whether a blocked_by_route execution has a matching worker. Cluster mode: the key lands on whatever slot CRC16 hashes to — enumeration goes through workers_index_key() rather than a keyspace SCAN, which would only hit one shard in cluster mode.

worker_key

Worker registration key.

workers_capability_key

Worker capability index.

workers_index_key

Global worker index — SET of connected worker_instance_ids. Single slot in cluster mode (no hash tag; CRC16 of the literal key). SADD on connect, SREM on empty-caps restart; SMEMBERS gives the enumerable universe the unblock scanner walks. Separate from ff:worker:{id} registration keys to keep the index membership cheap to read and independent of per-worker hash details.
