Workspace Replication: Change Data Capture

Change to memory management algorithm

We use Change Data Capture in several project in our company.
We identified a serious problem regarding memory management algorithm. Once a week we have a batch of jobs performing many modifications to replicated tables. This workload is characterized as a large series of small logs entries followed by large series of larger entries. There are multiple transactions of these characteristics running concurrently. This causes memory list managed by CDC agent to be extremely long and fragmented. The result is enormous CPU usage and very slow log records processing - beside this CPU usage the agent seems to be idle. No data is replicated to the target instance. The change is needed to process such type of workloads efficiently without interrupting business functions based on this functionality.
