Streams for bulk writing and transform

Coherence supports streams for bulk reading from caches - through AsyncNamedCache API - but there does not seem to be a stream API for bulk writing to a cache (did I miss it?).

We are looking for similar support in Coherence for what we can see in a competitor product, Ignite code shown here:

o open a stream (stmr) for writing to cache

o you can keep a reference to the stream and re-use between calls (loop illustrated here)

o the stream action can transform data if required (a simple increment here)

try (IgniteCache<Integer, Long> stmCache = ignite.getOrCreateCache(cfg)) {

                try (IgniteDataStreamer<Integer, Long> stmr = ignite.dataStreamer(stmCache.getName())) {
                    // Allow data updates.
                    stmr.allowOverwrite(true);

                    // Configure data transformation to count random numbers added to the stream.
                    stmr.receiver(StreamTransformer.from((e, arg) -> {
                        // Get current count.
                        Long val = e.getValue();

                        // Increment count by 1.
                        e.setValue(val == null ? 1L : val + 1);

                        return null;
                    }));

                    // Stream 10 million of random numbers into the streamer cache.
                    for (int i = 1; i <= 10_000_000; i++) {
                        stmr.addData(RAND.nextInt(RANGE), 1L);

                        if (i % 500_000 == 0)
                            System.out.println("Number of tuples streamed into Ignite: " + i);
                    }
                }

                // Query top 10 most popular numbers every.
                SqlFieldsQuery top10Qry = new SqlFieldsQuery("select _key, _val from Long order by _val desc limit 10");

                // Execute queries.
                List<List<?>> top10 = stmCache.query(top10Qry).getAll();

                System.out.println("Top 10 most popular numbers:");

                // Print top 10 words.
                ExamplesUtils.printQueryResults(top10);
}
