Cache maintenance

Introduction

You can view and manage all existing caches from the data caches page - to access this page, select caches from the dashboard navigation menu.

Need to know

During routine platform maintenance, cached data may be cleared. While we make a best effort to retain data for up to 7 days, it could be cleared sooner. Please design your process flows accordingly.

The data caches page

The data caches page is split into three sections: flow run caches, flow caches, and company caches:

Each cache is listed with the following details:

Item	Summary
Name	The name that was specified when the cache was created. Caches are created via the add to cache shape.
Flow	For flow and flow run caches, this is the name of the process flow which is using the cache. This information is not shown for company caches, as the cache might be used in any process flow within a company profile.
Created	The date and time that the cache was created.
Last accessed	The date and time that the cache was last accessed by a process flow. The cache may or may not have been updated with data at this time (even if there is no data to be added, the access date/time is logged).
Keys	The number of cache keys associated with this cache. Cache keys are created via the add to cache shape.
Size	The current size of the cache in proportion to the limit.
	Delete the cache (and all associated data).

If you have a lot of caches, you can search by name:

To access cache details for a particular cache, click on its name:

Cache details

When you select a cache from the list, an edit cache page is displayed:

From here you can:

• View and change the cache name

• View and change the maximum age (retention period)

• View usage information

• View cache contents

• Clear the cache

Viewing & changing the cache name

To change the name of the cache, simply update the name field in the upper cache details panel, then click the save button.

When the name is updated and saved, the change is immediately reflected in any add to cache shapes in process flows, where this cache is used.

The cache name must not include full stop (.) or colon (:) characters.

Viewing & changing the maximum age (retention period)

You can use the maximum age slider to change the cache retention period for a cache:

Note that:

• The maximum age for a flow run cache is 2 hours - this cannot be changed

• The maximum age for a flow or company cache can be changed to anything up to 7 days

Viewing usage information

The usage panel shows general usage information about the cache:

Here you can see:

Item	Summary
Size	The current size of the cache, shown with a percentage use indicator. The maximum cache size is 50MB
Created	The date and time that the cache was created.
Last accessed	The date and time that the cache was last accessed. This timestamp is updated even when no data was added to the cache.
Keys	The number of keys associated with this cache.

Viewing cache contents

The cache contents panel displays an entry for each cache key update. Information shown varies, depending on the cache type.

Flow run cache

The following details are displayed for each cache item in a flow run-level cache:

Item	Summary
Flow Run ID	The unique id of the process flow run that updated the cache key.
Started at	The date and time that the process flow run was started.
Key	The cache key name.
Page	If multiple pages are added to a cache (for example, if incoming data is paginated or batched via flow control shape) and the add to cache save all pages option is togged ON), each page is listed individually.
Unique key	The internal cache key.
	Click the 'eye' icon to view the content associated with this key. For example:
Size	The size of the cache key.

Flow cache / company cache

The following details are displayed for each cache item:

Item	Summary
Key	The cache key name.
Page	If multiple pages are added to a cache (for example, if incoming data is paginated or batched via flow control shape) and the add to cache save all pages option is togged ON), each page is listed individually.
Unique key	The internal cache key.
	Click the 'eye' icon to view the content associated with this key. For example:
Size	The size of the cache key.

Clearing the cache

To clear all current content in the cache, click the clear cache button:

This removes any existing data but leaves the cache in place so it can still be used in process flows.
