------------------------------------
Sprint: Usergrid 34

> ---------------------------------------------
>
> Key: USERGRID-1245
> URL: https://issues.apache.org/jira/browse/USERGRID-1245
> Project: Usergrid
> Issue Type: Story
> Affects Versions: 2.1.0
> Reporter: Jeffrey
> Assignee: Michael Russo
> Fix For: 2.1.1
>
>
> com.clearspring.analytics.hash.MurmurHash is found in the fasterutil
> dependency which is 16MB. We want to pare down the size of the REST WAR
> file. Let's see if there is an alternative.
> Here is the maven dependency:
> {code}
> <dependency>
> <groupId>com.clearspring.analytics</groupId>
> <artifactId>stream</artifactId>
> <version>2.7.0</version>
> </dependency>
> {code}
> Look for the com.clearspring.analytics package. Seems to be used in GCM
> Adapter:
> {code}
> private Batch getBatch( Map<String, Object> payload) {
> synchronized (this) {
> long hash = MurmurHash.hash64(payload);
> Batch batch = batches.get(hash);
> if (batch == null && payload != null) {
> batch = new Batch(notifier, payload);
> batches.put(hash, batch);
> }
> return batch;
> }
> }
> {code}
> Also the CountMinSketch is used from this dependency:
> org/apache/usergrid/services/notifications/impl/ApplicationQueueManagerImpl.java:111
> {code}
> final CountMinSketch sketch = new CountMinSketch(0.0001,.99,7364181); //add
> probablistic counter to find dups
> {code}
