Virtual Table Server (VTS) Single Connection and Multiple Connection Functions

Note: The functions for multiple connections have been deprecated, and support for multiple connections will be fully removed in a future version. It is therefore recommended to work with the single connection functions only.

Use single connection functions if the script connects to only one Virtual Table Server. See Virtual Table Server (VTS) Functions for Single Connection (lrvtc and vts.).

Use multiple connection functions if the script connects to more than one server. See Virtual Table Server (VTS) Functions for Multiple Connections (vtc and vts_multi).

Do not mix single connection functions and multiple connection functions in a script.

Most functions can be used in C language, C#, Java, and JavaScript scripts. See the individual function references for details.
