Database / BetterDB Interview questions
What are the key browser features in BetterDB for Valkey?
The Key Browser lets you scan and filter keys by wildcard pattern, such as user:*, session:*, or *:cache, so you can narrow a large keyspace down to the namespace you actually care about instead of paging through everything.
For each matching key it shows the type and TTL at a glance, which is usually enough to spot something obviously wrong, like a key that should have expired hours ago but hasn't.
A related Search Index Browser lists Valkey Search (FT) indexes in the sidebar, showing schema, field types, document counts, and indexing state, and it auto-detects whether the Search module is even available on the server, so the panel simply doesn't appear on a plain Valkey/Redis instance without it.
Which wildcard pattern would filter keys under a 'session' namespace?
