How to sync 300Gb, or set cursor value?

Q&A
1

Hello)

I need to transfer 300gb from MSSQL to Postgree using incremental synchronization.
Estimated it will take ~100 hours((( the table is rebuilt every 24 hours and throws me out

  1. Is it possible to set the cursor value to select only fresh data?

I found such a request in the Airbyte database:

UPDATE state SET state = jsonb_set(state, '{state, streams, 0, cursor}', '"2022-01-25T00:00:00.000000Z"', false) WHERE connection_id = '592fd59f-2aa9-4852-9d2b-8d12e269faa1';

But I don’t have a connection if i run: select * from state. There are other connections.

Please add cursor setting to the interface)

  1. I tried to use Octavia, but I did not find the cursor setting there((

  2. I tried to upload csv to the database, and then I need to incremental synchronization the view of the table, where there is already a date condition. But airbyte deletes all old data when sync starts(((

Please help me find a solution)

Hello there! You are receiving this message because none of your fellow community members has stepped in to respond to your topic post. (If you are a community member and you are reading this response, feel free to jump in if you have the answer!) As a result, the Community Assistance Team has been made aware of this topic and will be investigating and responding as quickly as possible.
Some important considerations that will help your to get your issue solved faster:

  • It is best to use our topic creation template; if you haven’t yet, we recommend posting a followup with the requested information. With that information the team will be able to more quickly search for similar issues with connectors and the platform and troubleshoot more quickly your specific question or problem.
  • Make sure to upload the complete log file; a common investigation roadblock is that sometimes the error for the issue happens well before the problem is surfaced to the user, and so having the tail of the log is less useful than having the whole log to scan through.
  • Be as descriptive and specific as possible; when investigating it is extremely valuable to know what steps were taken to encounter the issue, what version of connector / platform / Java / Python / docker / k8s was used, etc. The more context supplied, the quicker the investigation can start on your topic and the faster we can drive towards an answer.
  • We in the Community Assistance Team are glad you’ve made yourself part of our community, and we’ll do our best to answer your questions and resolve the problems as quickly as possible. Expect to hear from a specific team member as soon as possible.

Thank you for your time and attention.
Best,

Hi Alex, if the sync fails it start the next one using the previous state? What version of Airbyte and the connectors are you using? Latest one of Postgres has the per stream state and should be more stable.

Thank you for the answer.
I am using airbyte version 0.40.29 and last version connectors
When the connection fails it starts downloading the data from the beginning. Does not use the data that has already been downloaded.

_tmp tables after each unsuccessful update are accumulated and not deleted

If I could control the cursor, or load the data piece by piece, that would be great.

No, today not all sources and destionation have checkpoint. This is a feature Airbyte is working today.
