QueryPlanRequest

public QueryPlanRequest()

Method Detail

since

public long since()

Return the epoch time in millis for minimum bind capture time.

When set this ensures that the bind values used to get the query plan have been around for a while (e.g. 5 mins) and so reasonably represent bind values that match the slowest execution for this query plan.

since

public void since(long since)

Set the epoch time (e.g. 5 mins ago) such that the query bind values reasonably represent bind values that match the slowest execution for this query plan.

Parameters:

since - The minimum age of the bind values capture.

maxCount

public int maxCount()

Return the maximum number of plans to capture.

maxCount

public void maxCount(int maxCount)

Set the maximum number of plans to capture.

Use this to limit how much query plan capturing is done as query plan capture is actual database load.

maxTimeMillis

public long maxTimeMillis()

Return the maximum amount of time we want to use to capture plans.

Query plan collection will stop once this time is exceeded.

maxTimeMillis

public void maxTimeMillis(long maxTimeMillis)

Set the maximum amount of time we want to use to capture plans.

Query plan collection will stop once this time is exceeded. We use this to ensure the query plan capture does not use excessive amount of time - put too much load on the database.
