Slack produces a continuous stream of append-heavy events: messages, thread replies, reactions, and file activity across every channel and DM. The Erathos Slack connector syncs conversations, messages, thread replies, reactions, users, user groups, and file metadata from your workspace into ClickHouse over the Slack Web API.

ClickHouse is a columnar database built for low-latency analytical queries over large event volumes, which fits message streams well. Load your Slack history into ClickHouse to slice engagement by channel, team, or period, and back internal dashboards that need fast answers over large event tables.

## FAQ

### How do I connect Slack to ClickHouse with Erathos?

Erathos is a data ingestion platform built for reliability, transparency, and control. We help data teams connect their SaaS tools, such as Slack, to their data warehouse, without the maintenance cost of in-house pipelines or the opacity of traditional ETL tools. Our customers reduce pipeline maintenance by up to 80%.

### What Slack data does Erathos sync to ClickHouse?

Erathos syncs conversations, including public and private channels, group DMs, and DMs, along with messages, thread replies, reactions, bookmarks, pins, users and presence data, user groups and their members, file and file comment metadata, emoji, reminders, scheduled messages, and team data such as access and integration logs. The scopes you grant to your Slack bot token determine which endpoints and conversations are available.

### How often does Erathos synchronize Slack data to ClickHouse?

You can configure sync frequency at the table level, from every 5 minutes up to once per day. Message and file streams use incremental synchronization with a cursor, so each run processes only records newer than the last sync. Other Slack tables run as full refresh.

### What happens if a synchronization fails?

Erathos automatically detects failures and sends alerts to your email, Slack, or Discord with full execution context, not just 'job failed.' Smart retries handle transient errors, and every run is logged so your team can debug in minutes, not hours.

### Is there a free trial period for the Slack connector?

Yes. Every Erathos connector includes a 14-day free trial. Connect Slack to ClickHouse and start syncing immediately, no credit card required.
