Apache Pulsar Support Services That Cover Every Layer Your Messaging Platform Depends On
Ksolves handles your entire Apache Pulsar lifecycle from broker deployment to geo-replication and 24x7 managed apache pulsar support.
Production-Ready Apache Pulsar Cluster Design
Built for high throughput and fault tolerance, validated before go-live.
- Cluster sizing covering broker count, BookKeeper ensemble with minimum write quorum of 3 bookies, and ZooKeeper quorum setup
- BookKeeper bookie setup with dedicated SSDs for journal writes targeting fsync latency under 0.4ms and HDDs for ledger storage
- ZooKeeper local ensemble via conf/zookeeper.conf and global configuration store via conf/global-zookeeper.conf for geo-replication
- Pulsar Functions and Pulsar IO connector deployment for Kafka, Elasticsearch, and JDBC sink integration
- Full deployment documentation and runbooks handed over at project close
Fix Slow Brokers, Bookie Write Stalls, and Consumer Backlog Buildup
Tuned at the broker, BookKeeper, ZooKeeper, and consumer layers with validated baselines.
- Broker JVM heap and GC policy tuning to eliminate pauses that trigger ZooKeeper session expiry and topic ownership drops
- BookKeeper journal placement on dedicated SSDs and direct memory tuning to prevent OutOfDirectMemoryError
- Topic partitioning and bundle load balancing to distribute message workloads evenly across all active brokers
- ZooKeeper metadataStoreBatchingEnabled tuning to reduce RPC round trips under high metadata operation rates
- Consumer subscription type (Exclusive, Shared, Key_Shared, Failover) and backlog quota configuration per namespace
Real Apache Pulsar Errors, Diagnosed and Fixed Fast
From broker failures to bookie cookie corruption, Ksolves resolves incidents that take production messaging offline.
- Fix broker topic ownership drops: diagnose ZooKeeper session expiry from JVM GC pauses and tune metadataStoreSessionTimeoutMillis
- Fix BookKeeper InvalidCookieException: corrupted cookie on persistent volumes, resolved via bookkeeper shell decommissionbookie and ZooKeeper re-registration
- Fix BKNotEnoughBookiesException: diagnosed via bookkeeper shell listbookies, resolved by restoring bookie nodes or expanding the ensemble
- Fix consumer backlog growing: identify subscription type mismatch or Pulsar Functions worker lag via broker metrics
- Fix geo-replication lag: verify namespace replication policy, global ZooKeeper store availability, and backlog quota settings
Every Layer Secured. Audit Evidence Delivered.
Authentication, tenant isolation, and patching without disrupting live producers or consumers.
- JWT token or Kerberos authentication for broker, bookie, and ZooKeeper connections with role-based authorization per tenant and namespace
- TLS encryption for broker-to-client, broker-to-bookie, and broker-to-ZooKeeper communication with automated certificate renewal
- Tenant and namespace isolation with per-tenant quotas covering publish rate, backlog size, and storage retention limits
- Apache Ranger integration for fine-grained topic-level authorization across all Pulsar tenants and namespaces
- CVE monitoring and patch advisory for Pulsar, BookKeeper, ZooKeeper, and Java dependencies tied to your apache pulsar SLA support tier
Zero Downtime Pulsar Upgrades and Kafka Migration
Version upgrades and Kafka-to-Pulsar migrations with full rollback validation before cutover.
- Pre-upgrade audit covering deprecated broker and bookie configuration keys, BookKeeper ledger format, and ZooKeeper schema changes
- Rolling broker upgrade one broker at a time with ownership handover and consumer reconnection validation at each step
- BookKeeper bookie rolling upgrade with bookkeeper shell bookiesanity verification before each node proceeds
- Kafka to Pulsar migration using KoP (Kafka on Pulsar) protocol handler without application code changes
- Post-upgrade validation for broker ownership, bookie replication health, ZooKeeper quorum, and geo-replication lag
Apache Pulsar Monitoring Service
Every layer covered with structured diagnostic reports on a defined cadence.
- Prometheus and Grafana dashboards for broker publish rate, dispatch rate, message backlog, and end-to-end latency per namespace
- BookKeeper bookie journal and ledger write latency alerting with threshold notifications on disk saturation
- ZooKeeper session expiry and write latency alerting before brokers lose topic ownership
- Consumer subscription backlog alerts per namespace when unacknowledged messages exceed quota thresholds
- Monthly apache pulsar maintenance service reviews covering broker throughput, bookie disk growth, and geo-replication health

Frequently Asked Questions
Everything you need to know before choosing an apache pulsar support services partner.
24×7 managed Apache Pulsar support across brokers, BookKeeper bookies, ZooKeeper, Pulsar Functions, and geo-replication, plus backlog monitoring, Apache Pulsar health check reviews, version upgrades, and root cause analysis for every critical incident – delivered as part of our broader Big Data analytics services covering the full streaming and processing stack enterprises rely on.
Apache Pulsar broker errors are caused by ZooKeeper session expiry from JVM GC pauses, bundle load imbalance, or topic lookup timeouts after broker restart. Ksolves diagnoses via broker logs, tunes JVM heap and metadataStoreSessionTimeoutMillis, and runs pulsar-admin namespaces unload to restore broker stability.
Apache Pulsar not working after a restart is caused by bookies failing with InvalidCookieException, brokers unable to reach ZooKeeper, or Pulsar Functions workers failing due to incorrect pulsarFunctionsCluster in conf/functions_worker.yml. Ksolves repairs bookie cookie registration, corrects functions worker configuration, and validates full cluster health.
Apache Pulsar consumer lag occurs when consumers cannot process messages fast enough, receiverQueueSize is too high causing acknowledgment timeouts, or unacknowledged messages exceed the blockedConsumerOnUnackedMsgs threshold. Ksolves diagnoses via pulsar-admin topics stats, tunes receiverQueueSize, and switches to Shared subscription for parallel consumer scaling.
Debugging Apache Pulsar cluster issues starts with verifying ZooKeeper quorum via zkCli.sh, checking broker bundle load via pulsar-admin broker-stats load-report, and verifying bookie availability via bookkeeper shell listbookies. Ksolves follows a structured path covering ZooKeeper, broker GC logs, bookie disk, and geo-replication lag to identify root cause.
Apache Pulsar message delivery failures are caused by broker send queue full errors, consumers not acknowledging within ackTimeout causing redelivery, or Key_Shared subscriptions using default batching that breaks message routing. Ksolves configures BatcherBuilder.KEY_BASED for Key_Shared topics, tunes ackTimeout, and validates end-to-end delivery.
Caused by JVM GC pauses preventing ZooKeeper heartbeats and triggering session expiry. Ksolves tunes broker JVM heap and GC policy, adjusts metadataStoreSessionTimeoutMillis, and monitors bundle load balancing to restore stable topic ownership.
