Table-Level Configuration

Table-level settings override catalog defaults for a specific table. This is useful when a table has different compaction requirements — for example, a high-volume streaming table that needs more aggressive compaction than the catalog default.

  1. Go to Governance > Data Catalog from the side panel.
  2. Find and open the table details page:
    • Data Catalog tab: Search for the table by name and click it.
    • Data Explorer tab: Navigate through Catalog > Database > Table.
  3. Click the Maintenance tab. The Configuration sub-tab opens by default.

  1. Use the Enable maintenance toggle to enable or disable maintenance for this table.
  2. For each operation, choose one of three states:
    • Inherit: uses the catalog-level setting. The card shows the inherited state, for example "Enabled (Inherited from Catalog)".
    • Enabled: explicitly enables this operation for this table, regardless of the catalog setting.
    • Disabled: explicitly disables this operation for this table.
  3. To configure operation-specific thresholds, expand Advanced Settings on any enabled operation card and add the properties you want to override. See Advanced Configuration for all available options.
  4. Click Save Changes to save. Click Reset to discard unsaved changes.
Table Maintenance Defaults
  • Tables are disabled for maintenance by default. You must explicitly enable each one (V1 rollout safeguard).
  • Table maintenance can't be enabled while catalog-level maintenance is disabled.
