# Connfigure Chunk Cache

The chunk cache mechanism enables Milvus to pre-load data into cache memory on the local hard disk of the query nodes before it is needed. This mechanism significantly improves vector retrieval performance by reducing the time it takes to load data from disk to memory.
The chunk cache mechanism enables Milvus to pre-load data into cache on the local hard disk of the query nodes before it is needed. This mechanism significantly improves vector retrieval performance by reducing the time it takes to load data from disk to memory.

## Background

Before conducting queries to retrieve vectors, you need to load the data from object storage to the memory cache on the local hard disk of the query nodes. This is a time-consuming process. Before all data is loaded, Milvus may respond to some vector retrieval requests with a delay.
Before conducting queries to retrieve vectors, Milvus needs to load the data from object storage to the memory cache on the local hard disk of the query nodes. This is a time-consuming process. Before all data is loaded, Milvus may respond to some vector retrieval requests with a delay.

To improve the query performance, Milvus provides a chunk cache mechanism to pre-load data from object storage into the cache memory on the local hard disk before it is needed. When a query request is received, the Segcore first checks if the data is in the cache memory, instead of the object storage. If the data is in the cache memory, Segcore can quickly retrieve it from the cache memory and return the result to the client.

The `warmup` parameter determines whether Milvus pre-loads data from the object storage into the memory cache on the local hard disk of the query nodes before it is needed. This parameter defaults to `async`. Possible options are as follows:
The `warmup` parameter determines whether Milvus pre-loads data from the object storage into the cache on the local hard disk of the query nodes before it is needed. This parameter defaults to `async`. Possible options are as follows:

- `async`: Milvus pre-loads data asynchronously in the background, which does not affect the time it takes to load a collection. However, users may experience a delay when retrieving vectors for a short period of time after the load process is complete. This is the default option.
- `sync`: Milvus pre-loads data synchronously, which may affect the time it takes to load a collection. However, users can perform queries immediately after the load process is complete without any delay.

- Addressed the issue of slow disk index loading by dynamically patching the index parameters ([#30016](https://github.com/milvus-io/milvus/pull/30016)).
- Addressed the issue of slow disk index loading by dynamically patching the index parameters ([#30116](https://github.com/milvus-io/milvus/pull/30116)).
- Resolved the problem of changes made through the "alter collection" command not being persisted ([#30156](https://github.com/milvus-io/milvus/pull/30156)).
- Fixed the issue where read request rate limiting ultimately leads to the unavailability of the read service ([#30196](https://github.com/milvus-io/milvus/pull/30196)).
