PHP.TO.START 2013 - PHP e Redis

Approfondimento su una delle tecnologie più interessanti da affiancare a PHP nella produzione di applicativi scalabili e di ultima generazione: Redis. Il talk sarà strutturato in due parti: una prima metà introduttiva su Redis e le potenzialità che questa tecnologia offre nell'integrazione con PHP e case study sul suo utilizzo. La seconda parte mostrerà la semplicità di utilizzo con PHP, gli strumenti a disposizione dello sviluppatore e alcuni esempi pratici di integrazione con applicativi PHP (Caching, JobQueue, Sessions, Messaging).

1. & by Antonio De Patto ... a redis fan
2. Which one
3. Salvatore Sanfilippo aka antirez
4. ALL data-set in RAM
5. PERSIST 1) Periodic snapshot 2) In Append 3) Delegate to slave
7. Very fast about 100.000 queries/second
8. 5 different data structures • STRING • HASH • LIST • SETS • SORTED SETS
9. STRING Simple string or integer values
10. STRING Simple string or integer values GET Fetch the data stored at the given key SET Set the value stored at the given key DELETE Delete the value stored at the given key (works for all types) ex. SET users:anto "{'name': 'antonio', 'email':'anto80@gmail.com'}"
11. HASH Unordered mapping of keys to values of strings or integer values
12. HASH Unordered mapping of keys to values of strings or integer values HSET Stores the value at the key in the hash HGET Fetches the value at the given hash key HGETALL Fetches the entire hash HDEL Removes a key from the hash, if it exists ex. HSET users:1032 email anto80@gmail.com HSET users:searching anto80@gmail.com 1032
13. LIST Ordered sequence of strings
14. LIST Ordered sequence of strings RPUSH Push the value onto the right end of the list LRANGE Fetch a range of values from the list LINDEX Fetch an item at a given position in the list LPOP Pop the value from the left end of the list and return it ex. RPUSH zend:queue:log {'userId':12332,'UA':Opera/9.0 (Window....; en)'}
15. SET Unordered bag of unique strings
16. SET Unordered bag of unique strings SADD Add the item to the set SMEMBERS Return the entire set of items SISMEMBER Check if an item is in the set SREM Remove the item from the set, if it exists ex. SADD mycompany:myteam antonio giulio walter gianluca
17. SORTED SET (ZSET) Ordered mapping of string members to floating point scores, ordered by score
18. SORTED SET (ZSET) Ordered mapping of string members to floating point scores, ordered by score ZADD Add member with the given score to the ZSET ZRANGE Fetch the items in the ZSET from their positions in sorted order ZRANGEBYSCORE Fetch items in the ZSET based on a range of scores ZREM Remove the item from the ZSET, if it exists ex. ZADD game:users:1132 maxscore 2342
19. Redis to go? <?php $redis = new Redis(); $redis->connect('127.0.0.1', 6379); PhpRedis : https://github.com/nicolasff/phpredis
21. Sessions session.save_handler = redis session.save_path = "tcp://host1:6379?weight=1"
22. Cache
23. Queues BLPOP, BRPOP, RPOPLPUSH
24. PUB/SUB SUBSCRIBER SUBSCRIBER PUBLISHER PUBLISHER PUBLISHER PUBLISHER REDIS pub/sub
