# KV Indexer (Legacy)

> Overview of the legacy KV Indexer, its limitations, and why Rollytics is the recommended replacement.

⚠️ **Legacy / Deprecated**

KV Indexer is a legacy indexing solution and is not recommended for production
rollups.\
New deployments should use Rollytics instead.

Initia products discover indexer endpoints via the Initia registry (`chain.json`
→ `apis.indexer`).

## What KV Indexer Is

KV Indexer is an indexing system embedded directly inside Cosmos RPC nodes.

## Why KV Indexer Is Deprecated

KV Indexer does not scale well for production rollups:

* **Duplicated storage and reindexing**
  * Each RPC node stores its own index and must be reindexed individually
* **RPC performance impact**
  * Indexing competes with RPC traffic for CPU, memory, and I/O
* **No active development**
  * KV Indexer is deprecated and no longer receives bug fixes or feature
    improvements

Because of these fundamental limitations, KV Indexer is not the long-term
indexing solution for Initia rollups.

## When You Might Still See KV Indexer

You may still see KV Indexer on:

* Older rollups that have not yet migrated
* Existing RPC nodes with indexing enabled
* Local development or test environments

Its presence does not indicate an issue, but migration is strongly recommended.

## How to Disable KV Indexer

After migrating to Rollytics, KV Indexer can be disabled in
`~/.minitia/config/app.toml`:

```toml theme={null}
[indexer]
enable = false
```

Disabling KV Indexer reduces disk usage and removes unnecessary load from RPC
nodes.

## What to Use Instead

Initia recommends Rollytics as the production indexing solution.

Rollytics is Initia's dedicated indexing service:

* **Indexes once into a shared Postgres database**
* **Exposes KV Indexer endpoint-compatible APIs**
* **Runs separately from RPC nodes**

Rollytics is the long-term indexing solution for Initia rollups and should be
used for all production deployments.
