Yes I think in this case the overhead is marginal and you won't notice it. Although there is no CPU difference, I/O is typically much more "costly" these days than CPU. You have practically no chance of hitting the limit on an INT field unless you're dealing with a LOT of data (which 300,000 entries is NOT). References: Int reference on MSDN and Numeric/Decimal reference on MSDN Performance #1. Also at that point (considering you're using an auto increment PK, you'll be over 4 billions rows), you'll have bigger performance issues, and the overhead of a BIGINT compared to a INT will be the least of your concerns.

Changes to old pages (if ever necessary) could be deferred until then, but in the case of columns based on identities or sequences, I can't think of a realistic scenario where that would even happen. SELECT OBJECT_NAME(ind.OBJECT_ID) AS TableName. int, bigint, smallint, and tinyint . Wouldn't the next insert almost assuredly cause a page split and over the course of a day, do a fairly good job of trashing the Clustered index (CI) all over again?A very busy system that records several thousand or more inserts would likely start to see performance degrade across the business day, 24/7 operations may have trouble finding a windows to defrag the index (even using ONLINE=ON)Wouldn't the better fix be to use NEWSEQUENTIALID() as a default constraint for the column the CI is set on, so that future inserts are sequentially higher in value than prior ones (at least until the instance restarts, at which point you may wind up splitting pages again at first, but will setlle out of that as the new seed into NEWSEQUENTIALID() makes space? CONVERT(varchar, CAST( SUM(s.[used_page_count]) * 8 AS money), 1) AS IndexSizeKB, MAX(pa.data_compression_desc) AS CompType, FROM sys.dm_db_index_physical_stats(DB_ID(), NULL, NULL, NULL, 'DETAILED') indexstats, INNER JOIN sys.indexes ind ON ind.object_id = indexstats.object_id AND ind.index_id = indexstats.index_id, LEFT JOIN  sys.dm_db_partition_stats AS s ON s.[object_id] = ind.

How seriously can we take the success of the Standard Model when it has so many input parameters? Saving 1 million records, comparing time and storage, and retrieve them one by one, again measuring performance. Even with your indexes, the INSERT and DELETE have twice as many writes and you are only working with 1 row. All of this needs to be manages by SQL server, so managing an int will be much faster than an nvarchar(128).

Performance-wise, Int will be better than BigInt, and BigInt will be better than UniqueIdentifier. So for every row and every index that includes this value, we lose storage space. Before we take a look at the performance let's first take a look at some Index or not, int is a lot faster (the longer the varchar, the slower it gets). my tips deal with In this tip we will run through basically the same steps as the original tip, but this time we will measure the page splits encountered when inserting data for each of the following datatypes: integer, bigint, GUID and sequential GUID. Arithmetic overflow error converting expression to data type int. Given Obviously, the bigger the type, the bigger the table, the slower the queries (more I/O, bigger indexes, longer access time, result less likely to fit in the various caches, and so on). The filter (WHERE bid = 1) uses a sequence scan on one INT/BIGINT column while applying multiple aggregates to the abalance column, another INT/BIGINT columns.This query shows a slight performance edge for INT over BIGINT in the range of 2% to 3%. though it can be applied to any type that is internally an integer (BIGINT, DECIMAL, MONEY, . Still, a type conversion can cause performance issues. the index on the GUID column.

SQL Server Execution Times: CPU time = 2995 ms, elapsed time = 32904 ms. The ID column of a table holding customer order information was an INT datatype, and it was running out of numbers. Also, rather than using serial, varbinary(16) primary allows for one (we do this) to use uuid_short() for the primary key (not uuid – which is very slow to use as a primary, because it's a string) - which has the feature of ensuring that every record has a key which is unique across the entire database (indeed - network). > If we change the data type to bigint using ONLINE … fragmentation goes to 85.5%, That fragmentation seems to arise because of inefficient page allocation patterns.
