# Lazy {#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 {#creating-a-database}
|
