The Synthetic Transaction Latency: Read (ms) column displays the average time in milliseconds of local read requests processed by a node in the cluster.
The Synthetic Transaction Latency: Write (ms) column displays the average time in milliseconds of local write requests processed by a node in the cluster.
Synthetic Transaction read or write latency is the average time to complete a simple read or write operation to an Instaclustr controlled table on each node in the cluster. Reads and writes occur at QUOROM so and are the total operation time measured at the synthetic transaction client on the node.
The Synthetic Transactions are designed to isolate client application or data model/data condition related issues from basic cluster health issues. Synthetic transactions will not be impacted by client or data issues unless they get to the point of impacting the general health of the cluster.
