The Datastore API provides functions for interacting with a key-value store that has query capabilities.

Key-Value Operations

datastore.set(key, value)

Sets a value in the key-value store.

Example:

datastore.set("user:123", {name = "John", age = 30})

datastore.get(key)

Gets a value from the key-value store.

Example:

local user = datastore.get("user:123")
print(user.name)  -- prints "John"

datastore.del(key)

Deletes a value from the key-value store.

Example:

datastore.del("user:123")

Batch Operations

datastore.batch_set(kvs)

Sets multiple key-value pairs in a single operation.

Example:

local kvs = {
    {key = "user:1", value = {name = "Alice"}},
    {key = "user:2", value = {name = "Bob"}}
}
datastore.batch_set(kvs)

datastore.batch_get(keys)

Gets multiple values in a single operation.

Example:

local keys = {"user:1", "user:2"}
local values = datastore.batch_get(keys)
for _, value in ipairs(values) do
    print(value.name)
end

datastore.batch_del(keys)

Deletes multiple values in a single operation.

Example:

local keys = {"user:1", "user:2"}
datastore.batch_del(keys)
