Real time log viewer: reverse order, async load and refreshing on prepend entries

[manelio]

Scenario:

I'm building a real time viewer for a large event log.

Log entries are sequentialy numbered. Newest entries, greatest ids. Amout of entries is potentially huge.

For the sale of simplicity:

• Row height is fixed.
• There's an API that retrieves log entries: async getEntries(from, to).
• await getEntries(1, 5) = ['Entry 1', 'Entry 2', 'Entry 3', 'Entry 4', 'Entry 5']
• Suppose I'm only interested in latest n records (for a large n, ie 100,000). So count will be always <= 100_000, or even could be fixed to 100,000 (unexisting entries will be rendered blank)

My questions:

1. Recent entries must be shown first. Is there any way to deal with reverse order lists?

2. Is there any way to async load entries or ranges?

3. There will be a follow mode in which viewer automatically shows new entries. I can't find any example on this.
