Kusto function materialize has a limitation of 5GB size. This info was introduced in this article :https://learn.microsoft.com/en-us/azure/data-explorer/kusto/query/materializefunction

Materialize has a cache size limit of 5 GB. This limit is per cluster node and is mutual for all queries running concurrently. If a query uses materialize() and the cache can't hold any more data, the query will abort with an error.

If the amount of concurrency is large, does it mean that it is more error-prone? It will abort with an error if the cache can't hold more data. I want to know how to monitor how many spaces I used of materialize cache? Please help on this question. Thanks.
