RE: Steem Data Services (SDS) / Update Notice / Version 0.1.7b

in Witness Activities • last year

Hi steemchiller, sorry to bother you. I am a graduate student working on a research project. I found SDS very useful. I want to collect follow history data but I have some issues using the API. For example, https://sds0.steemworld.org/followers_api/getFollowHistory/steemchiller/1487426276-1688031076 only returns 2 records. It seems it does not return the complete records. Do you have any suggestions? Thank you!

    Hi, with the current configuration of the followers_api module you won't be able to retrieve entries older than 3 months, because it is configured with store_history_days = 90 (config can be seen via https://sds0.steemworld.org/followers_api/getConfig).

    So, currently there is no other way than traversing through all blocks' operations (for example with https://sds0.steemworld.org/blocks_api/getOpsInBlockRange/50000001-50000100/0/custom_json) and watch for custom_json ops with id = "follow". Not very efficient and will take a long time to go through the whole chain, but it would work.
