I have one question for downloading history archive. When we execute the captive core server, It starts to download and catch up the ledger file by stellar-core automatically. The data is stored in /tmp/captive-stellar-coreXXX. Is that right? and why are you doing this? I want to sync the block data and query all transaction data.

[version]

• horizon: v2.0.0
• stellar-core: v1.15.1

[the result of "ps -ef"]
