Difference between live and non-live tables

Real-time tables and non-real-time tables are two different types of tables in a database, and their main difference is that the data is updated at different times and in different ways.

1. Real-Time Table: A real-time table is a type of table in which data is written to the table in real-time from a data source. In a real-time table, the data update time is relatively short, usually a few seconds or even less time to write the data into the table. Real-time tables are usually used in situations where you need to get the latest data quickly, such as stock quotes, instant messaging, and other areas.

2. Non-real-time table: Non-real-time table means that the data in the table is not directly obtained from the data source in real time, but after processing and regularly inserted into the table type in batch. This means that non-real-time table data is updated over a longer period of time than real-time tables, which can take minutes, hours, or longer. Non-real-time tables are typically used for data summarization and analytical reporting, such as company performance summary reports.

In addition to the difference in data update time, there are some other differences between real-time and non-real-time tables:

- Data storage: Real-time tables store data differently than traditional tables, and require the use of some specialized technology to support real-time writing of data.

- Data Access Mode: Because the data of real-time table is updated quickly, it needs to be read and written in a more efficient way, usually using streaming read and write modes.

- Data consistency: real-time table data acquisition in real time, data update speed, so in the processing need to consider the consistency and integrity of the data.

In summary, real-time and non-real-time tables have their own occasions, and you need to choose according to the actual situation when using them.
