Chapter 8: Back to the Future with Time Travel
Dealing with data issues is never a pleasant job and especially so when you cannot determine when the data was changed or whether the data has been lost altogether. Snowflake provides an incredibly unique way of going back in time through the Time Travel feature. This chapter explores the various applications of the Time Travel feature and combines it with cloning to tackle common data loss and debugging issues.
The following topics will be covered in this chapter:
- Using Time Travel to return to the state of data at a particular time
- Using Time Travel to recover from the accidental loss of table data
- Identifying dropped databases, tables, and other objects and restoring them using Time Travel
- Using Time Travel in conjunction with cloning to improve debugging
- Using cloning to set up new environments based on the production environment rapidly
