OptionalbaseThe base directory where log files will be stored.
Each session will have its own .jsonl file inside this directory.
OptionaldeliveryThe delivery strategy for events.
immediate: Write each event to its file synchronously.buffered: Batch events in memory and flush them periodically.OptionalmaxThe maximum total number of events to keep in memory across all session buffers.
If the total exceeds this size, the oldest events from the largest buffer will be dropped.
This prevents unbounded memory growth.
Only applies to buffered delivery mode.
OptionalbatchThe number of events to collect in a session's buffer before triggering a flush.
Only applies to buffered delivery mode.
OptionalflushThe maximum time in milliseconds to wait before flushing buffers, regardless of their size.
Only applies to buffered delivery mode.
OptionaloverflowThe policy to apply when the maxBuffer limit is reached.
This determines how the sink behaves when it's under heavy load.
auto-flush: Immediately triggers a flush.drop-oldest: Discards the oldest events to make room for new ones.error: Throw on overflow (useful for tests).
