Warning 0x80049304: Data Flow Task 1: Warning: Could not open global shared memory to communicate with performance DLL data flow performance counters are not available. Not sure if you’re able to decipher the issue(s). Unfortunately, I ran into an issue when executing the task. A good example of this is location and sensing data, which has fairly complex skew patterns in reality that will break most spatial indexing systems at scale - it is hard to get a data set that demonstrates this, but it is fairly easy to generate a synthetic data set that generates the same bulk behavior.Purely synthetic data set generators can very accurately model real-world data patterns, it just requires the ability to generate complex skew behaviors and interactions in the data that do not rise above the noise floor in trivial samples.Ok, so I used the import wizard using UTC-8.
For example, if I want to simulate several types of skew and bias that move logically in space and time over the properties of the data set, it is pretty simple to do that.
The great thing about synthetic data set generators beyond producing data of unbounded size is that you can configure arbitrary distributions and properties of the data that test a broad range of characteristics not possible with real-world data sets. You can use the listed data sets to easily test basic correctness but you can’t use them to test scaling behaviors.Synthetic data sets are not interesting but neither are they random or unrealistic if built by a competent designer. Large data sets exist but they are often implausibly large to move around over the Internet. A big problem with these data sets are that they are small, trivial cases, which limits the amount and kind of testing you can do. When I was at MySQL/Sun/Oracle, we were expressly forbidden from trying to create any test datasets based on the data by their fleet of lawyers Februat 8:38 am.
