Having installed and ran horizon with captive-core, it seems that memory consumption is stable (~ 4.5 G). The disk space is though increasing while transactions keep coming. Around 10G/day.

From my understanding, the captive-core doesn't fetch all the history before to run. Would that mean the older data can also be removed?

Might be the answer to my own question. There is a HISTORY_RETENTION_COUNT setting that automatically removes the older data.
