# Unique identifier for this service instance.
# Used in logs (base field), metrics labels, and as the default Redis consumer name.
# IMPORTANT: must be unique per running instance for safe consumer-group operation.
# If two instances share the same INSTANCE_ID they will also share REDIS_CONSUMER_NAME,
# which causes consumer-group split-brain — the stream will not progress correctly.

# Log level: fatal | error | warn | info | debug | trace

# Redis connection URL — required; no default.
REDIS_URL=redis://localhost:6379

# Postgres / TimescaleDB connection URL — required; no default.
POSTGRES_URL=postgres://postgres:postgres@localhost:5432/trm

# Redis Stream name to consume from. Must match tcp-ingestion's REDIS_TELEMETRY_STREAM.
# In the deploy stack this is pinned via the shared REDIS_TELEMETRY_STREAM env
# var so neither service can drift from the other.
REDIS_TELEMETRY_STREAM=telemetry:teltonika

# Redis consumer group name. All Processor instances join this group.
REDIS_CONSUMER_GROUP=processor

# Redis consumer name. Defaults to INSTANCE_ID.
# Override only when running multiple instances that should appear as distinct consumers
# in the group (e.g. when INSTANCE_ID is not set to a unique value per container).
# REDIS_CONSUMER_NAME=processor-1

# Port for Prometheus /metrics, /healthz, /readyz HTTP server.

# Max records fetched per XREADGROUP call.
BATCH_SIZE=100

# BLOCK timeout (ms) on XREADGROUP when the stream is empty. 0 = no blocking.
BATCH_BLOCK_MS=5000

# Max rows per Postgres INSERT batch.
WRITE_BATCH_SIZE=50

# Max devices kept in the per-device in-memory state map. LRU eviction beyond this cap.
# Size each entry at ~500 bytes → 10 000 devices ≈ 5 MB. Raise for large fleets.
