In-memory database updates you make using Data Definition Language DDL and Data Manipulation Language DML commands are also durable; they are saved to the log on disk.
When you use the CREATE DATABASE, RESTORE DATABASE, and REPLICATE DATABASE commands, you can specify whether to use synchronous or asynchronous durability.
If the disk containing the log runs out of space, the database update transaction rolls back; no in-memory update is made.
Database durability (
SYNC DURABILITY) cannot be disabled.
RESTORE DATABASE, and
REPLICATE DATABASE commands explains whether synchronous or asynchronous durability is used if this durability setting is not specified.
Following a server restart, SingleStoreDB loads the server’s database partitions from disk to memory.
Run SHOW DATABASES with the
EXTENDED option to see which databases are recovering and to get an estimate for how long recovery will take.
You cannot connect to a database while it is recovering.
