Accumulo was running on an eleven node cluster. The continuous ingest test suite was running to generate load. Ten continuous ingest clients were running. The following screenshot shows the monitor master page. This page gives information about individual tables within accumulo. Continuous ingest is running against the table ci. The data generated by the continuous ingest test suite looks like the following. The data is random, but forms many giant linked list. Each ingest client continually generates linked list containing 25 million nodes. In the shell session below a few scans are issued to start following the linked list that the first node in the table is part of. root@test15 ci> scan 000000000135fbbe 074c:569c [] 2db1de18-cd37-407d-b060-481a0a214c90:000000002b2bcfe1:2e15cb9f62fd22ab:fe6f84c7 000000000d76dcc9 4f62:0647 [] 65f401e8-4f93-498c-bffa-ecc21a8645fd:000000000e7c2bbc:6fad98d023b8f146:a2c4d59f 0000000024e07be4 5e56:221d [] 5283b4bd-4f18-4af9-a242-c8053b095e04:000000001e1ad441:12de1d82f4a7bf2f:ae231a6a 000000003e13cb50 1d0a:415c [] 5944afab-8407-4391-9994-91b313e545dd:0000000002d61c91:4890a8885e54b714:d542fafa 00000000634d0aaa 310d:1e58 [] 2db1de18-cd37-407d-b060-481a0a214c90:000000000c9e8018:4111345bc9afe2bb:4cbfd774 000000007d378414 08d2:0066 [] 15ab8578-faae-4ebb-9827-26728be78476:0000000052de5aac:06202f405c60726d:8ad4911a 000000008c3615d8 3868:5f66 [] 8f47568c-a383-4910-83c9-36b75ac66440:0000000067faf572:750d567f3dd0c5bf:5ea938fe 0000000090be2a77 7f32:2ca4 [] 8f47568c-a383-4910-83c9-36b75ac66440:000000005912be62:47ac0c7bb89013f1:dff13db9 00000000a7ca8e58 360f:5763 [] a9f5e129-e260-4a0e-a763-c6e3ef7b3eb6:0000000030bff255:37c8226225c804ba:665f261f 00000000f1000713 5079:46bd [] 30af7f48-15ae-4ccb-81c9-4662ad74be92:0000000014d408e3:56a9dec63aed4d8f:0f2a44ec 000000017e3ca989 56ac:062b [] 30af7f48-15ae-4ccb-81c9-4662ad74be92:000000000a8926a1:0bd54c769871aa78:b8e61d77 --------------------------------------- hit any key to continue or 'q' to quit ----------------------------------------- root@test15 ci> scan -b 2e15cb9f62fd22ab -e 2e15cb9f62fd22ab 2e15cb9f62fd22ab 1fc1:1486 [] 2db1de18-cd37-407d-b060-481a0a214c90:000000002b1c8da1:53a9e4ba97e4a6e0:4a8bd624 root@test15 ci> scan -b 53a9e4ba97e4a6e0 -e 53a9e4ba97e4a6e0 53a9e4ba97e4a6e0 37f3:33a2 [] 2db1de18-cd37-407d-b060-481a0a214c90:000000002b0d4b61:1c16a4ae1bef9f1f:f03c869b root@test15 ci> scan -b 1c16a4ae1bef9f1f -e 1c16a4ae1bef9f1f 1c16a4ae1bef9f1f 07c8:7cd3 [] 2db1de18-cd37-407d-b060-481a0a214c90:000000002afe0921:2e3ec09a8d2fdf52:8b82be48
