Must be aware that rebuilding index take some time. You can create index in advance, that will slow down inserting data a little bit, but you will have index up to date. Use SHOW INDEX STATUS and SHOW JOBS and SHOW JOB <id> to verify status of the rebuild process.

Try

SUBMIT JOB STATS

then

SHOW STATS

if you only need to get the numbers of vertices and edges. It's better to use LIMIT and pagination when retrieving large amount of data.

Did that, index job was successfully completed.

You can do that in LOOKUP, such as

LOOKUP ON Post yield id(vertex) | LIMIT 10, 10

I'm fetching a node-induced subgraph. These vertex ids are my starting points.

i see, so you will need all the 58M Post vertices? In this case will you consider using client sdk instead of queries?

there's one for python as well, no?

yes. you may refer to: https://github.com/vesoft-inc/nebula-python/blob/master/example/ScanVertexEdgeExample.py

I've been using the python client already. Will switch to the scan approach then. Thanks!

welcome 🙂

I had a use case to get vertices entered and do with them something, and I set a timestamp property with index and used it to fetch vertices in specific time range, so i pick eg. one minute range and get thousands or even hundreds of thousands vertices entered in that range, then process them with some graph queries. Then get another batch in continues time frame without overlap and be able to process all vertices continuously. Maybe idea can fit your usecase.

@Kasper for python storage client, please use the master version for now, as there is a bug being fixed on scanning data, a release to pypi will be done later 🙂. Another thing to be noted is, the storage client requires to access metad and storaged directly.
