skip+limit return results, some data is missing

[QingZ11]

• NebulaGraph version is v3.3

When using the official basketballplayer data set + skip + limit in Cypher to do data pagination, I found a weird rule. As long as the number of skip is less than / equal to one-half of the limit, there will be data loss, which is less than one-third After about one hour, all data is lost:

statements as below:

(root@nebula) [basketballplayer]> match  ()-[e]->() return e  skip 100 limit 34
+-----------------------------------------------------------------------+
| e                                                                     |
+-----------------------------------------------------------------------+
| [:follow "player109"->"player125" @0 {degree: 90}]                    |
| [:serve "player111"->"team200" @0 {end_year: 2018, start_year: 2016}] |
