Which type of command is tstats?

The correct answer is A because the tstats command is a generating command. A generating command is a type of command that does not require a base search and can generate results from the summary data or the raw data. The tstats command is a generating command that can retrieve statistical information from the summary data, such as the accelerated data models or the data model summaries. The tstats command is similar to the stats command, but it is faster and more efficient, as it does not need to scan the raw data. The other options are incorrect because they are not the type of command that tstats is. Option B is incorrect because a transforming command is a type of command that converts the results into a data table with rows and columns. Option C is incorrect because a centralized streaming command is a type of command that processes the results on the search head, not on the indexers. Option D is incorrect because a distributable streaming command is a type of command that processes the results on the indexers, not on the search head.
