Question

我在Azure Sql中有内存表，其中插入的大量数据可能达到7000 /秒，到目前为止它消耗高达90％的高CPU。任何人都可以解释为什么以及如何改进它？

public class DetailActvityActionBtn implements View.OnClickListener {

private Activity activity;

public DetailActvityActionBtn(Activity activity){
    this.activity = activity;
}

@Override
public void onClick(View view){
    //You can now call activity.finish() to close the calling activity...
    activity.finish();
}

CREATE TABLE [dbo].[UserTransactions]
(
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [Points] [int] NOT NULL,
    [Date] [datetime] NOT NULL,
    [UserId] [int] NOT NULL,
    [DeviceId] [char](36) COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
    [TransactionTypeId] [tinyint] NOT NULL,
    [ActionBy] [int] NOT NULL,

INDEX [idx_hash_UserTransactions_UserId] NONCLUSTERED HASH 
(
    [UserId]
)WITH ( BUCKET_COUNT = 524288),
 PRIMARY KEY NONCLUSTERED 
(
    [Id] ASC
),
INDEX [UserTransactionsUIX_NonClustered] NONCLUSTERED HASH 
(
    [ActionBy],
    [TransactionTypeId]
)WITH ( BUCKET_COUNT = 262144)
)WITH ( MEMORY_OPTIMIZED = ON , DURABILITY = SCHEMA_AND_DATA )

    SELECT ISNULL(COUNT(*),0) from UserTransactions 
where ActionBy=@IBidId and TransactionTypeId=@TId
