# Data Sync Activity block

> Hourly data sync activity chart for all connections with a Runs or Rows toggle and a source filter

Data sync activity over 24 hours as Recharts columns stacked by outcome, under runs, landed, failed and rows synced stats. Tooltips name failing and slow connections; a menu exports CSV or copies a summary. ReUI Frame, Badge. ETL pipeline health.

## Best for

Activity pooled across many connections, filtered by source type, where an hour's tooltip names the failing and slow connections

## Agent notes

- Replace `RAW_CONNECTIONS` in data.tsx; each `pattern` string sets 24 hourly outcomes and `hoursOf` invents row counts with `prng`
- `refresh` only waits `REFRESH_MS`, replays the column rise and sets `synced` to just now; wire it to refetch your connection runs
- `INTEGRATION_CATEGORY` sets each integration's Sources group and Rows tooltip slice; a new `IntegrationId` also needs a mark in `INTEGRATION_LOGO`

## When not to use

- One source's hours above a list of its newest runs, durations and error text: use [Sync Run History](https://web.dev.reui.io/blocks/chart/bar-chart/chart-47.md) (`get_block("chart-47")`)
- The same hourly activity on a full connections page with a grid and a setup flow: use [Data Connections](https://web.dev.reui.io/blocks/solutions/dev-ops/solution-dev-ops-6.md) (`get_block("solution-dev-ops-6")`)

## About Bar Chart blocks

### When to use

- Amounts compared across years, weeks, categories or regions as prisms, patterned bars, pills or lanes
- Activity over time stacked by outcome, such as job runs, audit events, firewall requests or data syncs
- Run durations and error budgets read against a timeout, a warning line or a paging threshold

### When not to use

- A share of a whole where the slices read better around a ring: use the [Pie Chart blocks](https://web.dev.reui.io/blocks/chart/pie-chart.md)
- A capacity or allocation split into colored segments on one meter, with no axis: use the [Stats blocks](https://web.dev.reui.io/blocks/application/stats.md)
- Rows of jobs or deploys, each with its own run history strip: use the [Status Tracker blocks](https://web.dev.reui.io/blocks/chart/status-tracker.md)

### Agent notes

- `Chart` renders with no props and fetches nothing, so every bar, lane and limit is seeded from constants in the block folder
