Applications using Redis need to read related keys from one snapshot and update them only when all expected values still match. RedisKvStore now implements AtomicKvStore with getMany(), setMany(), deleteMany(), and casMany(), covering standalone Redis and one Redis Cluster hash slot while preserving the existing key encoding.
Redis scripts do not roll back earlier writes after a later command error. The adapter therefore encodes and validates the complete request before dispatch, then checks key reads and command permissions before entering a bounded mutation phase. Nonempty batches are accepted only on official Redis 7.2.17, 7.4.12, and 8.10.3, and are limited to 128 entries and 1 MiB of request data. These fixed limits and the exact release list keep execution within the audited scripting and Cluster behavior. Other releases reject nonempty batches until they are added explicitly.
Cluster calls require all effective physical keys to share a hash slot, including any ioredis client prefix. The adapter never adds a hash tag, relocates keys, or splits a batch. Existing deployments need an explicit data migration if they choose a new tagged namespace. Snapshots route to primaries, and batches bypass ioredis automatic pipelines so concurrent calls for different primaries remain independent. Normal client redirection and replay behavior still applies, so an uncertain response cannot establish whether an earlier attempt committed.
The change also rejects storing undefined, unencodable top-level JSON values, and CAS deletions with a non-null TTL, and fixes CAS success results for ioredis stringNumbers clients. Ordinary single-key calls retain their existing Redis version and TTL range support.
RedisKvStore adds atomic batch reads, writes, deletes, and compare-and-swap within documented Redis version and Cluster slot scopes. PostgreSQL expiry-index detection now compares the stored expression and has regression coverage for both documented expression forms.
RedisKvStore implements AtomicKvStore and uses scripts for batch snapshots and mutations. The scripts check supported versions, permissions, batch arguments, and CAS conditions.
Adapter validation and batch methods packages/redis/src/kv.ts, packages/redis/src/codec.ts, packages/redis/src/kv.test.ts
The adapter validates and encodes inputs, applies batch and TTL limits, and implements getMany(), setMany(), deleteMany(), and casMany(). Single-key set() and cas() use shared encoding and reply validation. CAS deletion with a TTL now rejects.
Conformance, routing, and failure tests packages/redis/src/kv.atomic*.test.ts, packages/redis/src/kv.test.ts, .github/workflows/main.yaml, packages/redis/deno.json, packages/redis/package.json
Tests cover supported versions, batch behavior, input rules, Cluster routing and migration, ACL and memory failures, and imports without Redis configuration. CI adds a version matrix for atomic tests. Test configuration adds required permissions and limits Node test concurrency to one.
Supported scope and usage documentation packages/redis/README.md, docs/manual/kv.md, claude-plugin/skills/fedify/SKILL.md, CHANGES.md, changes.d/redis/*
Documentation describes supported Redis versions and Cluster scope, limits, validation, failure behavior, and test setup. Changelogs record the Redis atomic operations.

Stored expression detection and regression coverage packages/postgres/src/kv.ts, packages/postgres/src/kv.index.test.ts, changes.d/postgres/expiry-index-expression.md, CHANGES.md
Index detection now compares the stored expression through pg_get_expr. The regression test checks reinitialization with both timezone() and AT TIME ZONE expressions.

Explanation
The title "Add atomic operations to RedisKvStore" matches the main change. The PR adds getMany(), setMany(), deleteMany(), and casMany() to RedisKvStore so it implements AtomicKvStore, as the raw summary and objectives describe. The title is short, specific, and names the class that changed.

The description states the purpose (snapshot reads and conditional multi-key updates), the new methods, the supported Redis releases, the 128-entry and 1 MiB limits, Cluster hash-slot constraints, the rejection of undefined and unencodable JSON values, and the CAS and stringNumbers fixes. It relates directly to the changeset.
Full details: Linked Issues check
Explanation
[#1365] The whole-PR summary shows implementation for each coding objective. RedisKvStore declares implements AtomicKvStore in packages/redis/src/kv.ts and adds getMany(), setMany(), deleteMany(), and casMany() with the signatures in the issue. cas() and the ordinary KV methods remain. Snapshot reads use the read-only atomicSnapshotScript. Mutations use atomicMutationScript, which checks ACL permissions and CAS conditions before any write. Values are pre-encoded. Keys, TTLs, and batch limits (128 entries, 1 MiB) are validated before dispatch. Nonempty batches are accepted only on Redis 7.2.17, 7.4.12, and 8.10.3. Cluster scope is explicit: all effective physical keys must share one hash slot, and cross-slot batches are rejected. The adapter adds no hash tag and relocates no data. The codec rejects undefined and unencodable top-level JSON values, and CAS comparison uses encoded bytes. Tests exist in kv.atomic.test.ts, kv.atomic-cluster.test.ts, kv.atomic-admin.test.ts, and kv.atomic-gates.test.ts. Documentation and changelog updates exist in docs/manual/kv.md, packages/redis/README.md, the skill guidance, and changes.d/redis/atomic-kv-store.md. CI adds atomic jobs for the three audited Redis versions and a three-primary Cluster. Limits: this assessment used the summaries only and did not read source files directly. The tests were not executed, so runtime behavior on Node, Deno, Bun, and Cluster is not established. Cluster, admin, and migration tests are opt-in and skip without fixtures. The issue requirement not to claim Cluster support before verification is addressed by the documented scope and the CI Cluster job, but that verification has not been observed.
Full details: Out of Scope Changes check
Explanation
The PostgreSQL expiry-index change does not relate to #1365, which covers RedisKvStore only. The whole-PR summary still lists these unrelated files: packages/postgres/src/kv.ts (expiry-index check changed from pg_get_indexdef to pg_get_expr), packages/postgres/src/kv.index.test.ts (new timezone() and AT TIME ZONE tests), changes.d/postgres/expiry-index-expression.md (changelog entry for PR #1434), and the PostgreSQL 18.7 note in root CHANGES.md. The PR description does not mention PostgreSQL, and the linked issue does not request PostgreSQL work. These changes do not support any Redis objective. The Redis changes (packages/redis/**, Redis docs, skill guidance, Redis changelog fragment, .github/workflows/main.yaml) remain within scope.
Resolution
Remove the PostgreSQL changes from this pull request: packages/postgres/src/kv.ts, packages/postgres/src/kv.index.test.ts, and changes.d/postgres/expiry-index-expression.md. Remove the PostgreSQL 18.7 note from the root CHANGES.md. If the PostgreSQL fix is needed, deliver it in a separate pull request with its own linked issue and changelog entry.

Review comments at @changes.d/redis/atomic-kv-store.md:
- Around line 10-12: Update the migration guidance around the Redis release
restrictions to explain that they preserve audited atomicity guarantees, tell
users to use a supported Redis release for nonempty batches, and instruct users
upgrading affected calls to remove TTLs from CAS deletions.
Review comments at @packages/redis/README.md:
- Line 102: Update the reservation example’s `casMany()` false-response comment
to state that an earlier attempt may have committed and to check a receipt or
version before re-evaluating the reservation rule.
Review comments at @packages/redis/src/kv.atomic-admin.test.ts:
- Line 208: Update the owner lookup in the administrative tests to match each
connection’s CLUSTER MYID against the node ID in the CLUSTER SLOTS range, rather
than matching ports. Apply the same change to the source lookup in the migration
setup, resolve the owner before the COUNTKEYSINSLOT loop, and keep target as a
different node.
Review comments at @packages/redis/src/kv.atomic-cluster.test.ts:
- Around line 308-309: Replace the TIME-based polling loop in the slow Redis
script with a finite, fixed-count Lua loop that does not read Redis’s cached
clock. Choose the iteration count to approximate the test’s intended delay,
preserving the slow-script test timing while ensuring the script terminates on
its own.
Review comments at @packages/redis/src/kv.atomic-gates.test.ts:
- Line 22: Update the Redis package’s `deno task test` permissions so the test
creating the temporary directory with `mkdtempSync` and starting the fixture
child process has the required write and run access. Keep the expanded
permissions scoped to this test task, or route the probe through a separately
permitted task, and preserve the fixture guard.

Applications using Redis need to read related keys from one snapshot and update them only when all expected values still match.
RedisKvStorenow implementsAtomicKvStorewithgetMany(),setMany(),deleteMany(), andcasMany(), covering standalone Redis and one Redis Cluster hash slot while preserving the existing key encoding.Redis scripts do not roll back earlier writes after a later command error. The adapter therefore encodes and validates the complete request before dispatch, then checks key reads and command permissions before entering a bounded mutation phase. Nonempty batches are accepted only on official Redis 7.2.17, 7.4.12, and 8.10.3, and are limited to 128 entries and 1 MiB of request data. These fixed limits and the exact release list keep execution within the audited scripting and Cluster behavior. Other releases reject nonempty batches until they are added explicitly.
Cluster calls require all effective physical keys to share a hash slot, including any ioredis client prefix. The adapter never adds a hash tag, relocates keys, or splits a batch. Existing deployments need an explicit data migration if they choose a new tagged namespace. Snapshots route to primaries, and batches bypass ioredis automatic pipelines so concurrent calls for different primaries remain independent. Normal client redirection and replay behavior still applies, so an uncertain response cannot establish whether an earlier attempt committed.
The change also rejects storing
undefined, unencodable top-level JSON values, and CAS deletions with a non-null TTL, and fixes CAS success results for ioredisstringNumbersclients. Ordinary single-key calls retain their existing Redis version and TTL range support.Closes #1365. Related to #1361.
