Camel is an Open Source integration framework that empowers you to quickly and easily integrate various systems consuming or producing data. This is a common SOA scenario. The snippet below:
- Search tweets in Twitter and returns to the web client
- Dump to disk at least one of tweets retrieved encoded in JSON in the folder
log/{year}/{month}/{day} - Compute metrics (available at
/actuator/metrics/per-keyword-messages?tag=keyword:${value}, values available athttp://localhost:8080/actuator/metrics/per-keyword-messages)
from(DIRECT_ROUTE)
.toD("twitter-search:\${header.keywords}") // Twitter search, returns a list of Tweets
.wireTap(LOG_ROUTE) // Copy the list of tweets to the LOG_ROUTE, which is processed by its own thread
.wireTap(COUNT_ROUTE) // Copy the list of tweets to the COUNT_ROUTE, which is processed by its own thread
// returns a list of tweets to the DIRECT_ROUTE caller
from(LOG_ROUTE)
.marshal().json(JsonLibrary.Gson) // Encode the list of tweets as JSON
.to("file://log?fileName=\${date:now:yyyy/MM/dd/HH-mm-ss.SSS}.json") // Write the JSON to a file
from(COUNT_ROUTE)
.split(body()) // Split the list in single Tweets
.process { exchange -> // Process a single Tweet
val keyword = exchange.getIn().getHeader("keywords")
if (keyword is String) {
keyword.split(" ").map {
perKeywordMessages.increment(it)
}
}
}The objective is to extend the query interface to support the command max:n, where n is a number.
max sets a limit in the number of retrieved tweets.
That is cool max:10 must return at most 10 tweets.
There are several ways to do it.
You can use the parameter q or create additional parameters.
There is a restriction.
You must explicitly tell the API Twitter to enforce such a limit.
Read the documentation of the Twitter Search component of Apache Camel to discover how.
You need to apply for a free Twitter developer account.
Do not add application.properties with the Twitter tokens to your git!
Note: the Twitter Search endpoint is configured using URI syntax twitter-search:{string}[?param=value[¶m=value]*]
Proposed:
- Use Camel for providing a WebSocket endpoint for queries; a websocket client is required.
- Use Camel for keeping a copy of responses in a database
- Enrich the response with moustache; remove moustache from the client.
- Create an operator "-" to filter out tweets that contain a keyword
The link provides one of the possible approaches. You can use a different one.
The possibilities of Camel are endless; you can propose your idea for a 🎁.
Manifest your intention first by a PR updating this README.md with your goal.
If you desist of your goal, release it by a PR so other fellow can try it.
