ClickHouse Active Part Count Growing: How To Fix

Operational guide to diagnosing and stopping ClickHouse active part count growth before it triggers insert delays, throttling, or too-many-parts errors.

ClickHouse cannot connect to ZooKeeper/Keeper: diagnosing the coordination layer

Diagnose and recover when ClickHouse loses its ZooKeeper or ClickHouse Keeper coordination layer, including connection checks, 4lw probes, and replica readonly states.

ClickHouse checksum mismatch and broken parts: detecting data corruption

Detect and remediate ClickHouse data corruption from checksum mismatches, broken parts, and detached parts before replication divergence spreads.

ClickHouse DB::Exception: Too many parts - causes and fixes

Troubleshoot and resolve ClickHouse exception code 252 when inserts fail because a partition has accumulated too many active parts.

ClickHouse DelayedInserts climbing: the warning before too-many-parts

Understand why ClickHouse DelayedInserts climbs, how the insert throttle works, and what to check before inserts start rejecting.

ClickHouse disk space collapse: why merges need free space and how the spiral starts

Why ClickHouse background merges need temporary disk headroom and how crossing the 85-90% threshold triggers a self-reinforcing spiral of stalled merges, accumulating parts, and accelerating consumption.

ClickHouse disk space monitoring: free_space, unreserved_space, and the 80% target

Understand ClickHouse disk space as an operational dependency, not just capacity. Interpret system.disks metrics, maintain merge headroom, and avoid the disk space death spiral.

ClickHouse distributed DDL stuck: ON CLUSTER queries that never finish

Diagnose and fix ON CLUSTER DDL queries that hang or never finish in ClickHouse. Identify stuck hosts, reconcile schema drift, and restore coordination with ZooKeeper or Keeper.

ClickHouse full table scan: partition pruning failures and the primary key

Diagnose why ClickHouse queries scan every row and how to fix partition pruning and primary key misalignment.

ClickHouse Keeper saturation spiral: too many tables, DDL storms, and cluster freeze

Diagnose and break the ZooKeeper/Keeper saturation spiral that turns replicated ClickHouse clusters read-only.

ClickHouse killed by the OOM killer: RSS, max_server_memory_usage, and cgroup limits

Why ClickHouse is killed by the Linux OOM killer even when internal memory tracking looks healthy, and how to close the gap between RSS and MemoryTracking.

ClickHouse long-running queries: finding and killing the resource hog

Operational guide for identifying, diagnosing, and terminating ClickHouse queries that consume excessive resources or stall indefinitely.

ClickHouse Memory limit (for query) exceeded: per-query limits and GROUP BY/JOIN blowups

Troubleshoot ClickHouse error code 241 when per-query memory limits breach, including high-cardinality GROUP BY, unbounded DISTINCT, and Cartesian-product JOINs.

ClickHouse Memory limit (total) exceeded - server-wide memory pressure and fixes

Diagnose and fix the ClickHouse server-wide MEMORY_LIMIT_EXCEEDED error (code 241) when MemoryTracking hits max_server_memory_usage.

ClickHouse memory pressure death spiral: runaway queries, retries, and OOM

Diagnose and break the feedback loop where memory pressure, query kills, retries, and spill-to-disk compound into cascading failure.

ClickHouse merge death spiral: when parts accumulate faster than merges consolidate

Break the feedback loop where ClickHouse inserts outrun background merges, parts pile up, and writes are delayed or rejected.

ClickHouse merges not keeping up: diagnosing a stalled or starved merge pool

Diagnose why ClickHouse background merges stall, starve, or fall behind, and fix the root cause before parts accumulate into a rejection crisis.

ClickHouse monitoring checklist: the signals every production cluster needs

A production monitoring checklist for ClickHouse organized by maturity level, from survival signals to expert diagnostics.

ClickHouse mutation stuck: parts_to_do not decreasing and how to recover

Diagnose and recover stuck ClickHouse mutations when parts_to_do stops decreasing, including quick checks, root causes, and safe remediation steps.

ClickHouse mutations silently blocking merges: the hidden cause of part growth

Why ALTER UPDATE/DELETE mutations starve the merge pool, how to spot the starvation before parts explode, and what to do about it.

ClickHouse No space left on device: emergency recovery when the data disk fills

Emergency recovery procedures and root-cause analysis for ClickHouse servers that hit disk-full conditions, including safe space reclamation and merge death-spiral prevention.

ClickHouse query error rate high: reading exception codes 241, 252, and 999

Triage a ClickHouse query error spike by exception code. Diagnose memory limits, too many parts, ZooKeeper issues, and schema drift using system.query_log and system.events.

ClickHouse query latency P99 spikes: tail latency, hot shards, and cold data

Diagnose and fix ClickHouse P99 query latency spikes caused by tail latency, hot shards, cold data, and resource contention.

ClickHouse Replica is lost: SYSTEM RESTORE REPLICA and recovering a diverged replica

Diagnose and recover a ClickHouse replica that has silently diverged from its peers using SYSTEM RESTART REPLICA and SYSTEM RESTORE REPLICA.

ClickHouse replication lag: absolute_delay, queue_size, and catch-up diagnosis

Diagnose ClickHouse replication lag using system.replicas, system.replication_queue, and background pool signals. Learn to tell a saturated fetch pool from a stuck mutation or a readonly replica.

ClickHouse replication queue stuck: num_tries, last_exception, and dead entries

Diagnose and fix stuck ClickHouse replication queue entries by reading num_tries, last_exception, and entry types instead of relying on delay alone.

ClickHouse small inserts anti-pattern: why single-row inserts melt the merge pool

Understand how single-row and micro-batch inserts create part accumulation in ClickHouse, the signals that expose the pattern, and the client-side fixes that actually work.

ClickHouse Table is in readonly mode: is_readonly on replicated tables and how to fix it

Diagnose and recover replicated ClickHouse tables stuck in readonly mode caused by lost Keeper sessions, coordination failures, or quorum loss.

ClickHouse too many partitions: why over-partitioning multiplies your part count

How high-cardinality partition keys in ClickHouse create thousands of isolated part pools, why parts never merge across partitions, and how this drives per-partition limit violations.

ClickHouse Too many simultaneous queries: max_concurrent_queries and query storms

Diagnose and fix ClickHouse query storms when max_concurrent_queries is reached, including retry amplification and concurrency saturation.

ClickHouse ZooKeeper session has expired: causes, recovery, and tuning

Diagnose and recover when ClickHouse replicas lose ZooKeeper sessions, become read-only, and stop accepting writes.

How To Tune ClickHouse Async Inserts: Key Settings

Understand when ClickHouse server-side async insert buffering genuinely reduces part creation versus when it silently relocates too-many-parts risk into an in-memory buffer.
