Major Description
Dear sir,
I am running Ignite in my project about with three nodes:
Three nodes: "ubuntu7","ubuntu8","ubuntu9"
cacheConf.setIndexedTypes(String.class, String.class)
cacheConf.setCacheMode(CacheMode.PARTITIONED);
cacheConf.setAtomicityMode(CacheAtomicityMode.ATOMIC);
When using above setting for
- Put,
- putAll,
- SqlFieldsQuery,
- IgniteJdbcThinDriver,
- IgniteDataStreamer add
- IgniteDataStreamer addAll
, there are a situation about data latency, and the experiment results are in the following.
One node(ubuntu7)
| milliseconds | 1,000 | 10,000 | 100,000 | 500,000 | 1,000,000 |
| Put | 401 | 1,108 | 3,874 | 12,636 | 23,561 |
| putAll | 146 | 428 | 2,092 | 8,940 | 17,854 |
| SqlFieldsQuery | 282 | 943 | 4,522 | 20,821 | 41,223 |
| IgniteJdbcThinDriver | 491 | 1,581 | 8,938 | 41,429 | 80,599 |
| IgniteDataStreamer Add |
152 | 439 | 2,161 | 7,374 | 12,296 |
| IgniteDataStreamer addAll |
101 | 234 | 2,028 | 5,037 | 9,181 |
Two nodes(ubuntu7 write and ubuntu8)
| milliseconds | 1,000 | 10,000 | 100,000 | 500,000 | 1,000,000 |
| Put | 1,185 | 5,481 | 26,142 | - | - |
| putAll | 107 | 292 | 1,785 | - | - |
| SqlFieldsQuery | 786 | 3,195 | 30,528 | - | - |
| IgniteJdbcThinDriver | 859 | 3,569 | 34,080 | - | - |
| IgniteDataStreamer add |
169 | 410 | 1389 | - | - |
| IgniteDataStreamer addAll |
99 | 206 | 988 | - | - |
Three nodes(ubuntu7 write, ubuntu8, and ubuntu9)
| milliseconds | 1,000 | 10,000 | 100,000 | 500,000 | 1,000,000 |
| Put | 1,664 | 7,794 | 41,116 | - | - |
| putAll | 101 | 294 | 1,911 | - | - |
| SqlFieldsQuery | 1,086 | 5,718 | 41,997 | - | - |
| IgniteJdbcThinDriver | 1,247 | 4,899 | 48,566 | - | - |
| IgniteDataStreamer add |
168 | 385 | 1,364 | - | - |
| IgniteDataStreamer addAll |
86 | 249 | 905 | - | - |
From above results, these tables show that the three ways: put, SqlFieldsQuery, IgniteJdbcThinDriver have gradually bad performance on data latency with increasing ignite server nodes, and the other ways: putAll, IgniteDataStreameradd, and IgniteDataStreameraddAll have better performances.
I don't know if the testing via my java codes are suitable and correct to show these results or not.
Here, i provide my codes to reproduce my experimental situation.
Attached is my codes for your reference.
if any further information is needed, I am glad to be informed and will provide to you as soon as possible.
If you have any idea about this issue, I am looking forward to hearing from you.
Yours sincerely,
Rick
