----------------------------------
Summary: [storm-redis] Add basic lookup / persist bolts
Key: STORM-691
URL: https://issues.apache.org/jira/browse/STORM-691
Project: Apache Storm
Issue Type: Improvement
Affects Versions: 0.10.0
Reporter: Jungtaek Lim
Assignee: Jungtaek Lim
Priority: Minor
Currently storm-redis provides AbstractRedisBolt for normal (not Trident) Bolt.
Jedis is easy to use so it may be enough, but we can also provide
implementations of AbstractRedisBolt for simple usage.
eg. store (key, value) pair, get key's value
Since Redis has various data types and commands, we can't cover whole things,
but seems like below things could be considered.
|| Type || Read || Write ||
| STRING | GET (key) | SET (key, value) |
| HASH | HGET (key, field) | HSET (key, field, value) |
| LIST | LPOP (key) | RPUSH (key, value) |
| SET | SISMEMBER (key, member) | SADD (key, member) |
| SORTED SET | ZSCORE (key, member) | ZADD (key, score, member) |
| HLL (HyperLogLog) | PFCOUNT (key) | PFADD (key, element) |
Btw, since we will normally get key & value from tuple (as most external module
did), HASH, SET, SORTED SET needs additional key to process.
