--- title: "Implementation" url: https://docs.catalyst.zoho.com/en/cloud-scale/help/cache/implementation/ description: "Catalyst provides a robust, fully-managed cache in-memory for real-time use cases to store ephemeral data in your applications." last_updated: 2026-09-28T11:04:26Z service: Cloud Scale type: general --- # Implementation The implementation section acts as a step-by-step procedure guide on working with Catalyst cache from the Catalyst console. You can refer to the [Java](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/cloud-scale/cache/get-segment-instance/), [Node.js SDK](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/cloud-scale/cache/get-segment-instance/), [Python SDK](https://docs.catalyst.zoho.com/en/sdk/python/v1/cloud-scale/cache/get-segment-instance/) and the [API documentation](https://docs.catalyst.zoho.com/en/api/code-reference/cloud-scale/cache/insert-key-value-in-segment/#InsertKeyValueinCacheSegment) for working with cache from the respective environments. ### Create a Segment You can only create a cache segment from the Catalyst console. It cannot be done using the APIs. > **Note:** Catalyst allows you to create up to 20 segments in a project in the [development environment](https://docs.catalyst.zoho.com/en/deployment-and-billing/environments/introduction/). The size limit of each segment is 5 MB in the development environment. You can request Catalyst for an increase in these limits by contacting our support at support@zohocatalyst.com. We will address each request on a case-by-case basis. There are no upper limits for segments in the production environment. To create a cache segment: 1. Navigate to **Cloud Scale**, and then **Cache**. ![Cache- Create a Segment](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache.webp) 2. Click **Create Segment** in the *Segments* page. 3. Enter the segment name in the pop-up window. ![Cache- Create a Segment](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_create.webp) 4. Click **Create**. Your cache segment will now be created and listed in the *Segments* page, along with details like segment ID, created by, and created time. ![Cache- Segment Created](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_segments.webp) The default segment will already be present in the *Segments* page. ### Rename a Segment To rename a cache segment: 1. Click the ellipsis icon for the segment that needs to be renamed in the *Segments* page, and then click **Rename**. ![Cache- Rename a Segment](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_segments_edit.webp) 2. Type a new name for your segment and press **Enter**. ![Cache- Rename a Segment](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_segment_rename.webp) ### Create a Cache Item To create a cache item: 1. Click the name of the segment from the *Segments* page where the cache item should be created. 2. Click **Create Cache Item**. ![Cache- Create a Cache Item](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_item.webp) 3. Enter a keyname, value, and the expiration time in hours for the cache item. ![Cache- Create a Cache Item](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_create_cache_item.webp) > **Note:** * The keyname of a cache item is unique for a segment. * If you do not enter a value for the expiry time, it is automatically set to the default validity (two days). 4. Click **Create**. The cache item will be created and listed in the segment's page. ![Cache- Cache Item Created](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_key_details.webp) You can find a particular cache item by searching using its keyname in the search bar. ### Edit a Cache Item To edit a cache item: 1. Click on the name of the segment whose cache item you want to edit, in the _Segments_ page. 2. Click on the key name and click **Edit** in the _Key Details_ window. 3. Make the necessary edits to the cache item. ![Cache- Edit a Cache Item](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_edit_cache_item.webp) 4. Click **Save**. The cache item will be updated. ### Delete a Cache Item To delete a cache segment: 1. Click on the name of the segment whose cache item you want to delete, in the _Segments_ page. 2. Click on the key name and click **Delete** in the _Key Details_ window. ![Cache- Delete a Cache Item](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_delete_cache_item.webp) 3. Click **Yes, Proceed** in the confirmation window. ![cache](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_delete_cache_item_confirmation.webp) The cache item will now be deleted permanently. ### Delete a Segment To delete a cache segment: 1. Click the ellipsis icon for the segment that needs to be deleted and click **Delete**. ![Cache- Delete a Segment](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_segment_delete.webp) 2. Click **Yes, Proceed** in the confirmation pop-up window. ![cache](https://catalyst-docs-development.zohostratus.in/images/help/cache/catalyst_cache_segment_delete_confirmation.webp) The segment will now be deleted permanently.
