SQL Server Performance Office Hours Episode 13
| What is the effect of having a few queries using Read Committed isolation level where the database is set to RCSI? Will those dumb Read Committed queries block any others? |
| Do you have any suggestions for optimizing data retrieval using Full Text Search (FullTextMatch TVF)? We’ve tried cutting down the query to reduce the dataset using other parameters before the FTS bit and also breaking out FTS across multiple columns to do one at a time, but anything else? Also, the memory used by FullTextMatch is hard to define. Should we reduce the size of the BufferPool to give more to FTS or the other way around? Thank you for coming to my Ted Talk on FTS. |
| If I were to want to kill all the table partitions by fire, what brand of flamethrower do you recommend? |
| Do you know of any documentation that makes it very obvious what Max Server Memory controls? It’s changed across versions. I think it used to just be the buffer pool? |
| I am writing C# classes and building CLRs for string comparisons, then creating a TVF for execution. The TVF is creating row estimates of exactly 1000x my row actuals (2 rows creates a “2 of 2000” for example). No query hints seem to resolve this, how would you work to control these estimates from my compiled C#? |
