# Lazy
|
|
|
|
Keeps tables in RAM only `expiration_time_in_seconds` seconds after last access. Can be used only with \*Log tables.
|
|
|
|
It's optimized for storing many small \*Log tables, for which there is a long time interval between accesses.
|
|
|
|
## Creating a Database
|
|
|
|
```
|
|
CREATE DATABASE testlazy ENGINE = Lazy(expiration_time_in_seconds);
|
|
```
