SQLite data files to the Linux memory file system/dev/shm/data.sqlite3, is the memory-level read and write performance of the SQL system.
Use SQLite to implement memory key value storage:
CREATE TABLE IF not EXISTS memory (
Key VARCHAR (+) not NULL PRIMARY key,
Value TEXT not NULL,
Time INTEGER not NULL
);
INSERT into memory (key, value, time) VALUES (' Key1 ', ' value1 ', 1484033720);
INSERT into memory (key, value, time) VALUES (' Key2 ', ' value2 ', 1484033724);
SELECT * from memory WHERE key = ' key1 ';
