             Summary: Investigate more recent or alternative Promise implementations
                 Key: HRJS-63
                 URL: https://issues.jboss.org/browse/HRJS-63
             Project: Infinispan Javascript client
          Issue Type: Task
            Reporter: Galder Zamarreño


The current Promise implementation ({{promise:7.0.4}}) can have misleading GC behaviour. If you create a promise out of a big number of promises, any linked function callbacks via {{.then()}} will still see all the garbage generated by the Promises. Only when one of those {{.then()}} functions returns a new Promise will all previous Promises and related memory consumption be garbage collected.

Create a test that replicates this and verify whether newer implementations handle it better, or whether alternative implementations avoid this issue.

An example of this can be found [here|https://gist.github.com/galderz/ba1bb305b8c592cbece3da566edfb12b]. In this [other example|https://gist.github.com/galderz/38d3a0ed42729129167bbb7c2cfc3163] the problem is avoided by generating a new promise after handling the big Promise.
