Why teams connect Apache Cassandra and Monday

Mirror Monday's data into Apache Cassandra so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Monday through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Apache Cassandra.

Stacksync mirrors Items, Subitems, Column values, Groups from Monday into Materialized Views, Secondary Indexes, User-Defined Types, Collections in Apache Cassandra and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Monday, so the tool and the database never disagree.

Common use cases

  • 01 Push support tickets or orders from an operational database into monday.com Items, then read status Column values back when work completes.
  • 02 Sync Updates and status changes from monday.com into a database so downstream tools and dashboards react to project progress in near real time.
  • 03 Consolidate data from multiple keyspaces or clusters into one reporting store.
  • 04 Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.

Common sync patterns

Automate Monday from your codebase

Write to the synced tables in Apache Cassandra and Stacksync propagates the change into Monday, replacing custom integration code.

React to changes as they happen

Updates in Monday arrive as row changes in Apache Cassandra, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

What you can sync between Apache Cassandra and Monday

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Apache Cassandra objects Monday objects How this pairing syncs
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Items Rows within a board and the primary record; synced two-way and created, updated, archived, or deleted via GraphQL mutations. Partitions and Rows is specific to Apache Cassandra and Items to Monday — each maps to any object or custom field on the other side.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Subitems Nested rows under items, stored on a separate hidden board; synced as a child table linked to the parent item. Materialized Views is specific to Apache Cassandra and Subitems to Monday — each maps to any object or custom field on the other side.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Column values Typed fields (status, date, people, numbers, connect-boards); polymorphic JSON usually written together via change_multiple_column_values. Secondary Indexes is specific to Apache Cassandra and Column values to Monday — each maps to any object or custom field on the other side.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Groups Named sections that group items inside a board; synced as a grouping attribute or category field on the row. User-Defined Types is specific to Apache Cassandra and Groups to Monday — each maps to any object or custom field on the other side.
Collections List, set, and map columns handled with type-aware field mapping. Updates Comment and activity threads attached to items; read out into a database for reporting or written back as notes. Collections is specific to Apache Cassandra and Updates to Monday — each maps to any object or custom field on the other side.
Counters Increment-only counter columns, usually read-only in syncs. Users Account members referenced by people columns; read to resolve owner and assignee IDs to names and emails. Counters is specific to Apache Cassandra and Users to Monday — each maps to any object or custom field on the other side.

How changes propagate between Apache Cassandra and Monday

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Apache Cassandra Monday Sub-second propagation

DetectionChanges in Apache Cassandra are captured at the source via change data capture — no polling loop against its API. Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns.

DeliveryEach detected change is written to Monday through its API, with automatic retries and rate-limit backoff.

Monday Apache Cassandra Sub-second propagation

DetectionMonday notifies Stacksync of record changes through webhook events. Board-scoped webhooks (create_item, change_column_value, item_deleted, and similar) for real-time events.

DeliveryEach detected change is written to Apache Cassandra through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apache Cassandra: No API quotas; throughput is governed by cluster capacity and consistency-level choices.
  • Monday: Complexity-budget limits: a single query caps at 5M complexity points and ~10M points/min per user token (1M on trial/free) over a sliding 60s window.
