I am trying to generate a file for mass insertion in shape:
SET Key0 Value0
SET Key1 Value1
...
SET KeyN ValueN
In my case, I have newlines in values. How to write values in this case since \n means new command. Can I use quotation mark to wrap a value with a newline character?
Redis doesn't care about what you store as string values. What may be getting in your way is the client/programming language that you're using.
For example, the below is the output of using the redis-cli tool that ships with Redis:
$ redis-cli
127.0.0.1:6379> SET foo "1st\n2nd"
OK
127.0.0.1:6379> GET foo
"1st\n2nd"
127.0.0.1:6379> QUIT
$ redis-cli --raw
127.0.0.1:6379> GET foo
1st
2nd

When getting all the keys from Redis, like this:
redis.server.com:6379> keys *
1) "z13235jxby03knne1w1gucl5"
Instead of manually copying the long key to execute get z13235jxby03knne1w1gucl5, I'd like to run something like get $(1) (pseudo code) to get the value at position 1, as output by the keys command.
Is this possible, if not, is there any workaround to not have to manually copy paste?
Note, I don't want to solve this with a script, then I prefer just copy and paste it
off the top of my head, I'm not aware of a way from inside the cli.
But, Regardless of any performance implications, you can pipe the cli command lines together , but you have to do it from the shell
redis-cli --raw KEYS "*" | sed -n 1p | xargs redis-cli GET
where the 1 in :
sed -n 1p
is the line number (1-based index) inside KEYS output.
but still you need to do your validations; like making sure the index is withing the nuber of keys returned by the KEYS command all keys are of simple string type ; not sets, hash maps, etc...
I'd like to periodically scan thru a redis instance for keys that changed since the last scan. in between the scans i don't want to process the keys.
eg one key could get a thousand updates between scans. i care for the most recent value only when doing the next periodic scan.
There is no built-in way in Redis to achieve that (yet).
You could, for example, recode your app and add some sort of a way to track updates. For example, wherever you're calling SET foo bar, also call ZADD updated <timestamp> foo. Then, you can use the 'updated' Sorted Set to retrieve updated keys.
Alternatively, you can try using RedisGears to automate the tracking part (for starters). Assuming that you have RedisGears running (i.e. docker run -it -p 6379:6379 redislabs/redisgears), you can do something like the following:
$ cat gear.py
def addToUpdatedZset(x):
import time
now = time.time()
execute('ZADD', 'updated', now, x['key'])
return x
GB().filter(lambda x: x['key'] != 'updated').foreach(addToUpdatedZset).register('*')
$ redis-cli RG.PYEXECUTE "$(cat gear.py)"
OK
$ redis-cli
127.0.0.1:6379> KEYS *
(empty list or set)
127.0.0.1:6379> SET foo bar
OK
127.0.0.1:6379> KEYS *
1) "updated"
2) "foo"
127.0.0.1:6379> ZRANGE updated 0 -1 WITHSCORES
1) "foo"
2) "1559339877.1392548"
127.0.0.1:6379> SET baz qux
OK
127.0.0.1:6379> KEYS *
1) "updated"
2) "baz"
3) "foo"
127.0.0.1:6379> ZRANGE updated 0 -1 WITHSCORES
1) "foo"
2) "1559339877.1392548"
3) "baz"
4) "1559339911.5493586"
i'm trying to set a variable sized object in Redis but this value sometime is being truncated when its size is bigger than 4087 bytes.

I have readed that the string value can be at max 512 Megabytes in length. I also try to found some configuration but couldn't find anything.
How can i store a value bigger than 4K in Redis?
I think the limitation you are seeing is coming from readline which interactive Redis uses to provide an editable command history.
I assume you don't really want to start 512,000,000 copies of the letter A so let's assume you want to store a 400kB JPEG, you can do this in Terminal:
redis-cli -x HSET YourKey ImageData < image.jpg
Of course, if you do want to store 500,000 letter As:
dd if=/dev/zero bs=500 count=1000 | LC_ALL=C tr '\000' 'A' | redis-cli -x HSET MYKEY AS
In Redis, keys user* will print all keys starting with user.
For example:
keys user*
1) "user2"
2) "user1"
Now, I want all keys that don't start with user to be printed.
How could I do that?
IMPORTANT: always use SCAN instead of (the evil) KEYS
Redis' pattern matching is somewhat functionally limited (see the implementation of stringmatchlen in util.c) and does not provide that which you seek ATM. That said, consider the following possible routes:
Extend stringmatchlen to match your requirements, possibly submitting it as a PR.
Consider what you're trying to do - fetching a subset of keys is always going to be inefficient unless you index them, consider tracking the names of all non-user keys (i.e.g. in a Redis Set) instead.
If you are really insistent on scanning the entire keyspace and match against negative patterns, one way to accomplish that is with a little bit of Lua magic.
Consider the following dataset and script:
127.0.0.1:6379> dbsize
(integer) 0
127.0.0.1:6379> set user:1 1
OK
127.0.0.1:6379> set use:the:force luke
OK
127.0.0.1:6379> set non:user a
OK
Lua (save this as scanregex.lua):
local re = ARGV[1]
local nt = ARGV[2]
local cur = 0
local rep = {}
local tmp
if not re then
re = ".*"
end
repeat
tmp = redis.call("SCAN", cur, "MATCH", "*")
cur = tonumber(tmp[1])
if tmp[2] then
for k, v in pairs(tmp[2]) do
local fi = v:find(re)
if (fi and not nt) or (not fi and nt) then
rep[#rep+1] = v
end
end
end
until cur == 0
return rep
Output - first time regular matching, 2nd time the complement:
foo#bar:~$ redis-cli --eval scanregex.lua , "^user"
1) "user:1"
foo#bar:~$ redis-cli --eval scanregex.lua , "^user" 1
1) "use:the:force"
2) "non:user"
#Karthikeyan Gopall you nailed it in your comment above and this saved me a bunch of time. Thanks!
Here's how you can use it in various combinations to get what you want:
redis.domain.com:6379[1]> set "hello" "foo"
OK
redis.domain.com:6379[1]> set "hillo" "bar"
OK
redis.domain.com:6379[1]> set "user" "baz"
OK
redis.domain.com:6379[1]> set "zillo" "bash"
OK
redis.domain.com:6379[1]> scan 0
1) "0"
2) 1) "zillo"
2) "hello"
3) "user"
4) "hillo"
redis.domain.com:6379[1]> scan 0 match "[^u]*"
1) "0"
2) 1) "zillo"
2) "hello"
3) "hillo"
redis.domain.com:6379[1]> scan 0 match "[^u^z]*"
1) "0"
2) 1) "hello"
2) "hillo"
redis.domain.com:6379[1]> scan 0 match "h[^i]*"
1) "0"
2) 1) "hello"
According to redis keys documentation the command supports glob style patterns, not regular expressions.
and if you look at the documentation, you'll see that the "!" character is not special as opposites to regular expressions.
Here is a simple test I ran in my own db:
redis 127.0.0.1:6379> set a 0
OK
redis 127.0.0.1:6379> set b 1
OK
redis 127.0.0.1:6379> keys *
1) "a"
2) "b"
redis 127.0.0.1:6379> keys !a
(empty list or set) // I expected "b" here
redis 127.0.0.1:6379> keys !b
(empty list or set) // I expected "a" here
redis 127.0.0.1:6379> keys [!b]
1) "b"
redis 127.0.0.1:6379> keys [b]
1) "b"
redis 127.0.0.1:6379> keys [ab]
1) "a"
2) "b"
redis 127.0.0.1:6379> keys ![b]
(empty list or set)
So I just don't think what you are trying to achieve is possible via the keys command.
Besides, the keys command is not very suitable for production environment as it locks your whole redis database.
I would recommend getting all the keys with the scan command, store them locally, and then remove them using LUA
Here's a trick to achieve this with native redis commands (no need for Lua scripts or anything).
If you are able to control the timing of when you insert the new keys (the ones you want to keep, deleting all other stuff like in your question), you can:
Before setting the new keys, set the expiration to all existing keys (by pattern or everything) to expire right now (see how)
Load the new keys
Redis will automatically delete all the older keys and you will be left just with the new ones you want.
You also can print all keys and pass it to grep. For example:
redis-cli -a <password> keys "*" | grep -v "user"
This is my first question here on stackoverflow.
Dear community, thanks a lot for your combined knowledge and expertise !
I'm new to Redis so please bear with me, as I'm sure there is a simple solution.
redis-server --version
=> Redis server v=2.6.14 sha=00000000:0 malloc=libc bits=64
redis-cli --version
=> redis-cli 2.6.14
I have read "How to use Redis mass insertion?"
How to use Redis mass insertion?
I have googled and read a lot of praise for the redis INCR feature. But I don't really understand everything and it does not help me to do this redis-internally only.
My goal:
I want to import 'n' lines of text into redis and retrive them later in exactly this order.
For each line I set a unique key, like key:1, key:2, key:3 etc.
By using an increasing counter as part of the key I am able to later retrieve the lines in the same order in which they were stored in redis.
Now (without redis mass insert) I solve this easily
by using an awk script to generate redis-cli calls, like:
cat data.txt | awk -f myscript.awk | bash
"data.txt" looks like this:
This is the first line.
This here is the much longer second line.
"myscript.awk" looks like this:
#!/usr/bin/awk -f
### This section is being applied before any line is read:
BEGIN {
# Set counter initially to Zero
print "redis-cli SET counter 0"
}
### This section is being applied per line read into awk:
{
# Increase counter by One
print "redis-cli INCR counter"
# Read current counter from redis into an variable
print "MYCOUNTER=`redis-cli GET counter`"
# Use this variable as counter for the key
print "redis-cli SET key:$MYCOUNTER \"" $0 "\""
# Retrive stored value from redis for illustration
print "redis-cli GET key:$MYCOUNTER"
}
The output of "cat data.txt | awk -f myscript.awk | bash" is:
OK
(integer) 1
OK
"This is the first line."
(integer) 2
OK
"This here is the much longer second line."
So everything is fine.
But instead of calling "redis-cli" twice per imported line
I want to use the redis "mass insert" feature. Here I need your help:
How would I do something like this in redis only ?
SET counter 0
=> OK
INCR counter
=> (integer) 1
GET counter
=> "1"
SET KEY:{counter} "Content of line 1"
=> OK
INCR counter
=> (integer) 2
GET counter
=> "2"
SET KEY:{counter} "Different content of line 2"
=> OK
etc., etc.
The "GET counter" lines are just for illustration.
Any help is appreciated. Thanks again !

Use a list for this. There's no reason to use a new key for each line. All the list commands are here, but the one you want is RPUSH. You can rpush many values at once in the same line, so you'll just do that:
RPUSH some_key line1 line2 ... lineN
Then to retrieve:
LRANGE some_key 0 -1
Quick and easy!
