How to retrieve only a predefined number of results in Azure Tables - azure

Question

I am trying to perform an azure table query.
My table (that saves logs) has thousands of rows of data, and it gets populated with more each second.
Right now i have only 1 partition key, but it doesn't affect the next question.
How can i get back lets say only the 100 latest results.
this is my Entity:
public MainServerLogEntity(string Message)
{
this.PartitionKey = "mainserverlogs";
this.RowKey = (DateTime.MaxValue.Ticks - DateTime.UtcNow.Ticks).ToString();
this.Message = Message;
this.Date = DateTime.UtcNow;
}
public MainServerLogEntity() { }
public string Message { get; set; }
public DateTime Date { get; set; }
Right now this is the query i am performing inside a web api i have:
[Route("MainServerLogs")]
[HttpGet]
public IEnumerable<MainServerLogEntity> GetMainServerLogs()
{
CloudTable table = AzureStorageHelpers.GetWebApiTable(connectionString, "mainserverlogs");
TableQuery<MainServerLogEntity> query = new TableQuery<MainServerLogEntity>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "mainserverlogs"));
return table.ExecuteQuery(query);
}
But the problem is that i am getting alot of data, and i am requesting this api every few seconds in order to update the ui.
What should i do? is it possible to define in the query that i only want the 100 first rows?
If it is not possible then what other technique should i use?

Answer 1

Try implementing a .Take(100) on the query like so:
[Route("MainServerLogs")]
[HttpGet]
public IEnumerable<MainServerLogEntity> GetMainServerLogs()
{
CloudTable table = AzureStorageHelpers.GetWebApiTable(connectionString, "mainserverlogs");
TableQuery<MainServerLogEntity> query = new TableQuery<MainServerLogEntity>().Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "mainserverlogs")).Take(100);
return table.ExecuteQuery(query);
}
