Overview

This is to inform all users that we've recently implemented three safety limits to Alloy’s engine.

These have been put in place to help ensure that the performance, reliability and security of Alloy remains high. Rest assured, these limits have been calculated carefully, so most users will never reach them!

In rare cases where a limit is reached, users will receive a detailed error message to inform them what has happened, so the situation can be avoided in future.

Who will be affected?

These limits affect all users of Alloy but will be unnoticeable by most.

Details

The following limits have been added.

Maximum Background Tasks

The number of background tasks that can be queued per customer project. This has been limited to 100,000 tasks, which is far higher than has ever been reached before.

If the limit is reached, attempting to create a task will fail with this error:

Error Category: ResourceLimited,  Error Code: 1657552956

Maximum Item Size

The size of any item being operated on. This has been limited to 2MB (roughly 420,000 words of text) for optimal resource management.

If the limit is reached, the operation will fail with this error:

Error Category: ItemSizeExceedLimit, Error Code: 1657279454

Maximum Items to Query in Bulk

The total number of items involved with any write operations. While a query may only affect a moderate number of items directly, each item may have child/parent items that need querying too. Therefore, this has been limited to 200,000 items on the Task Executor (75,000 items on the API services).

If the limit is reached, the query will fail with this error:

Error Category: BulkQueryLimitExceeded
