Configuration Parameters (11)
LANGFUSE_INGESTION_QUEUE_PROCESSING_CONCURRENCYrecommended: lower than default
Controls parallel job processing; lowering reduces memory spikes at cost of throughput
LANGFUSE_INGESTION_CLICKHOUSE_WRITE_BATCH_SIZErecommended: lower than default
Controls data batched per write; lowering reduces memory consumption
LANGFUSE_TOKEN_COUNT_WORKER_POOL_SIZErecommended: lower than 2 (default)
Tokenizer thread pool; high values cause pending requests to accumulate in memory
NODE_OPTIONSrecommended: --max-old-space-size=6144
Caps Node.js heap to container memory limit, prevents runaway usage
web.startupProbe.initialDelaySecondsrecommended: 60
Allows time for initial migrations before first health check
web.livenessProbe.initialDelaySecondsrecommended: 120
Prevents premature restart during migration completion
web.readinessProbe.initialDelaySecondsrecommended: 120
Delays readiness check until migrations complete
web.startupProbe.periodSecondsrecommended: 15
Check interval during startup phase
web.livenessProbe.periodSecondsrecommended: 15
Check interval for liveness
web.startupProbe.failureThresholdrecommended: 5
Number of failures before pod restart
container_versionrecommended: v3.x
V3 contains major performance improvements to address CPU spikes
