# Maintenance with Nimtable

> Use Nimtable to spot and act on Iceberg maintenance needs alongside RisingWave.

## What Nimtable tracks

* Tables needing compaction
* Recent compaction jobs and outcomes
* Watchlist entries for tables you want to track closely

## How to act

* Trigger compaction or optimization via your preferred engine (for example, Spark or a RisingWave job) while using Nimtable for visibility and coordination
* Use file and partition layout views to decide when to compact or rewrite manifests

## Using Nimtable as a REST Catalog for RisingWave

* Expose Nimtable’s REST endpoint to RisingWave and create Iceberg sources, sinks, or internal tables with `catalog.type = 'rest'`
* Keep storage credentials aligned or use vended credentials if your REST stack provides them

## Good practices

* Compact small files before downstream queries peak
* Monitor snapshots after large writes to ensure manifest counts stay healthy
* Pin critical tables to the watchlist to avoid missing compaction windows
