I need to insert some millions records in seconds in Cassandra. Using one client with asyncExecute with folllowing configs:
maxConnectionsPerHost = 5 maxRequestsPerHost = 32K maxAsyncQueue at client side = 100K I could achieve 25% of throughtput i needed, client CPU is more than 80% and increasing number of threads cause some execAsync to fail, so configs above are the best the client could handle. Cassandra nodes cpu is less than 30% in average. The data has no locality in sake of partition keys and i can't use createSStable mechanism. Is there any tuning which i'm missing in client side, cause the server side is already tuned with datastax recomendations. Sent using Zoho Mail
