First, functional requirements:The corresponding script file is called through the FreeSWITCH IVR key, and Nodejs provides many modules, which can easily communicate with other systems or in any form, my application is to send HTTP POST requests via Nodejs;Because I'm not familiar with the way freeswitch directly transfers the execution of the Nodejs file, I execute a LUA script that executes a call to the Nodejs file in a LUA script and executes it w
FS does not load Chinese speech by default. The Chinese module needs to be compiled first in the SRC of FS.
The unloading (do not restart FS) command is
Make Mod_say_zh-install
Then load the module on the FS console
Load MoD _say_zh
If you want FS to load the module every time it is started,
The following examples
1. Store the Chinese voice packet in the/usr/local/freeswitch/sounds/en/us/callie directory. Name en. That is the/usr/local/freeswitch/sounds/en/us/callie/zh
2. Edit the file in/usr/

Statistics of SQL Server research-discover and process expired statistics, and analyze SQL statisticsPreface:
Statistical information is the main source of information about data distribution in predicates. If you do not know the specific data distribution, the optimizer cannot obtain the estimated data set and therefore cannot count the data to be returned.
After the statistical information of a column is
Summary: Statistical information for the query:So far, the selection index and maintenance index have been introduced. If you have an appropriate index and update statistics in real time, the optimizer chooses a useful index for querying, because the SQL Server optimizer is cost-based optimization. When the data on the where and on columns needs to be displayed in the result set, if there is real-time statistics

Overview MySQL statistics and mysql statistics
MySQL executes SQL statements through SQL parsing and query optimization. The parser splits the SQL statements into data structures and passes them to subsequent steps, the query optimizer finds the best solution for executing SQL queries and generates execution plans. The query optimizer determines how SQL is executed and depends on the database
ObjectiveThe query optimizer uses statistics to create query plans that improve query performance, and for most queries, the query optimizer has generated the necessary statistics for a high-quality query plan, but in rare cases you need to create additional statistics or modify the query design to get the best results. Therefore, understanding and rational use o

Understanding SQL Server statistics and SQL statistics
Preface
SQL Server queries are based on overhead queries. When an execution plan is generated for the first time, a better execution plan is determined based on multi-stage analysis optimization. The base estimation of these overhead is determined based on the statistical information. The statistical information is the segmentation distribution of the

In essence, we want queries to ru
