Hello @rbotzer . There are 2 nodes and the server is hosted in AWS with T2.large instance type.
Given below are the aerospike config parameters:
transaction-queues=8;transaction-threads-per-queue=8;transaction-duplicate-threads=0;transaction-pending-limit=20;migrate-threads=1;migrate-xmit-priority=40;migrate-xmit-sleep=500;migrate-read-priority=10;migrate-read-sleep=500;migrate-xmit-hwm=10;migrate-xmit-lwm=5;migrate-max-num-incoming=256;migrate-rx-lifetime-ms=60000;proto-fd-max=15000;proto-fd-idle-ms=60000;proto-slow-netio-sleep-ms=1;transaction-retry-ms=1000;transaction-max-ms=1000;transaction-repeatable-read=false;dump-message-above-size=134217728;ticker-interval=10;microbenchmarks=false;storage-benchmarks=false;ldt-benchmarks=false;scan-max-active=100;scan-max-done=100;scan-max-udf-transactions=32;scan-threads=4;batch-index-threads=4;batch-threads=4;batch-max-requests=5000;batch-max-buffers-per-queue=255;batch-max-unused-buffers=256;batch-priority=200;nsup-delete-sleep=100;nsup-period=120;nsup-startup-evict=true;paxos-retransmit-period=5;paxos-single-replica-limit=1;paxos-max-cluster-size=32;paxos-protocol=v3;paxos-recovery-policy=manual;write-duplicate-resolution-disable=false;respond-client-on-master-completion=false;replication-fire-and-forget=false;info-threads=16;allow-inline-transactions=true;use-queue-per-device=false;snub-nodes=false;fb-health-msg-per-burst=0;fb-health-msg-timeout=200;fb-health-good-pct=50;fb-health-bad-pct=0;auto-dun=false;auto-undun=false;prole-extra-ttl=0;max-msgs-per-type=-1;service-threads=40;fabric-workers=16;pidfile=/var/run/aerospike/asd.pid;memory-accounting=false;udf-runtime-gmax-memory=18446744073709551615;udf-runtime-max-memory=18446744073709551615;sindex-builder-threads=4;sindex-data-max-memory=18446744073709551615;query-threads=6;query-worker-threads=15;query-priority=10;query-in-transaction-thread=0;query-req-in-query-thread=0;query-req-max-inflight=100;query-bufpool-size=256;query-batch-size=100;query-priority-sleep-us=1;query-short-q-max-size=500;query-long-q-max-size=500;query-rec-count-bound=18446744073709551615;query-threshold=10;query-untracked-time-ms=1000;pre-reserve-qnodes=false;service-address=0.0.0.0;service-port=3000;mesh-address=10.0.1.80;mesh-port=3002;reuse-address=true;fabric-port=3001;fabric-keepalive-enabled=true;fabric-keepalive-time=1;fabric-keepalive-intvl=1;fabric-keepalive-probes=10;network-info-port=3003;enable-fastpath=true;heartbeat-mode=mesh;heartbeat-protocol=v2;heartbeat-address=10.0.1.80;heartbeat-port=3002;heartbeat-interval=150;heartbeat-timeout=10;enable-security=false;privilege-refresh-period=300;report-authentication-sinks=0;report-data-op-sinks=0;report-sys-admin-sinks=0;report-user-admin-sinks=0;report-violation-sinks=0;syslog-local=-1;enable-xdr=false;xdr-namedpipe-path=NULL;forward-xdr-writes=false;xdr-delete-shipping-enabled=true;xdr-nsup-deletes-enabled=false;stop-writes-noxdr=false;reads-hist-track-back=1800;reads-hist-track-slice=10;reads-hist-track-thresholds=1,8,64;writes_master-hist-track-back=1800;writes_master-hist-track-slice=10;writes_master-hist-track-thresholds=1,8,64;proxy-hist-track-back=1800;proxy-hist-track-slice=10;proxy-hist-track-thresholds=1,8,64;udf-hist-track-back=1800;udf-hist-track-slice=10;udf-hist-track-thresholds=1,8,64;query-hist-track-back=1800;query-hist-track-slice=10;query-hist-track-thresholds=1,8,64;query_rec_count-hist-track-back=1800;query_rec_count-hist-track-slice=10;query_rec_count-hist-track-thresholds=1,8,64
We even changed the following config parameters but it further increased the latency:
query-batch-size=1000
query-short-q-max-size=100000
query-long-q-max-size=100000
query-threads=28
query-worker-threads=400
query-req-max-inflight=1000
