self-contained, serverless, zero-configuration, transactional Redis-compatible database engine. rlite is to Redis what SQLite is to SQL.
require "redis" require "hirlite/connection" redis = Redis.new(host: ":memory:", driver: Rlite::Connection::Hirlite) redis.set "key", "value" puts redis.get "key" # => "value"
Ruby bindings example. See golang, Java, Node.js, Objective-C, PHP, Python, R, and Rust
#include <hirlite.h>
// ...
rliteContext *context = rliteConnect(":memory:", 0);
rliteReply* reply;
int argc_set = 3;
char *argv_set[] = {"SET", "key", "value"};
size_t argvlen_set[] = {3, 3, 5};
reply = rliteCommandArgv(context, argc_set, argv_set, argvlen_set);
rliteFreeReplyObject(reply);
int argc_get = 2;
char *argv_get[] = {"GET", "key"};
size_t argvlen_get[] = {3, 3};
reply = rliteCommandArgv(context, argc_get, argv_get, argvlen_get);
if (reply->type == RLITE_REPLY_STRING) {
// reply->str is "value", reply->len is 5
}
rliteFreeReplyObject(reply);
This is a list of possible use cases where you might want to use rlite.
Mobile. If you are used to Redis data structure, and it is better suited for your mobile application than sqlite, you can use rlite as a database.
Replace Redis in development stack. By being embedded, rlite does not need a separate database process, and since it is compatible with Redis you can use it while developing, even if you use Redis instead in production.
Replace Redis in tests. The test stack can use rlite instead of Redis if you use the latter in production. It can simplify the CI stack, and the distribution of fixtures by being in binary form, and it will not require to load completely in memory to run each test.
Slave of Redis. You can run rlite-server as a slave of a master Redis instance. It works as third alternative to Redis's snapshot and append-only file.
Store client-side application data. Alternatively to a propetary format or sqlite, command line or simple applications can store its data using rlite.
All rlite data is stored in a single file using its own format. The format is not rdb or aof since those are optimized for fast reading the whole content and not for random access.
If file system persistence is no needed, use the magic file path ":memory:".
For more information about the file format check out its documentation.
Current Status and Roadmaprlite has no dependencies, just run make all.
