Analytics Configuration Parameters

activeMemoryGlobalBudget

The memory budget (in bytes) for the active runtime.

67108864 (64 MB)

activeStopTimeout

The maximum time (in seconds) to wait for a graceful stop of an active runtime.

3600

activeSuspendTimeout

The maximum time (in seconds) to wait for a graceful suspend of an active runtime.

3600

analyticsHttpRequestQueueSize

The maximum number of HTTP requests to queue pending ability to execute.

256

analyticsHttpThreadCount

The number of threads to service HTTP requests.

16

clusterConnectRetries

Number of attempts to contact CC before giving up.

5

collectDcpStateFromNodesTimeout

The maximum time to wait to collect DCP state from all nodes in seconds.

600

compilerFramesize

The page size (in bytes) for computation.

32768 (32 kB)

compilerGroupmemory

The memory budget (in bytes) for a group by operator instance in a partition.

33554432 (32 MB)

compilerJoinmemory

The memory budget (in bytes) for a join operator instance in a partition.

33554432 (32 MB)

compilerParallelism

The degree of parallelism for query execution. Zero means to use the storage parallelism as the query execution parallelism, while other integer values dictate the number of query execution parallel partitions. The system will fall back to use the number of all available CPU cores in the cluster as the degree of parallelism if the number set by a user is too large or too small.

0

compilerSortmemory

The memory budget (in bytes) for a sort operator instance in a partition.

33554432 (32 MB)

coresMultiplier

The factor to multiply by the number of cores to determine maximum query concurrent execution level.

3

deadlockWatchdogHaltDelaySeconds

The delay (in seconds) to wait for graceful shutdown due to deadlocked threads, before halting.

120

deadlockWatchdogPollSeconds

The frequency (in seconds) to scan for deadlocked threads.

300

jobHistorySize

Limits the number of historical jobs remembered by the system to the specified value.

10

jobQueueCapacity

The maximum number of jobs to queue before rejecting new jobs.

4096

jvmArgs

JVM args to pass to the Analytics Driver.

<undefined> (null)

logLevel

The logging level.

DEBUG

maxWebRequestSize

The maximum accepted web request size in bytes.

52428800 (50 MB)

netBufferCount

Number of network buffers per input/output channel.

1

netThreadCount

1

resultSweepThreshold

The duration within which an instance of the result cleanup should be invoked in milliseconds.

60000

resultTtl

Limits the amount of time results for asynchronous jobs should be retained by the system in milliseconds.

86400000

storageBuffercacheMaxopenfiles

The maximum number of open files in the buffer cache.

2147483647

storageBuffercachePagesize

The page size in bytes for pages in the buffer cache.

131072 (128 kB)

storageMaxActiveWritableDatasets

The maximum number of datasets that can be concurrently modified.

8

storageMemorycomponentNumcomponents

The number of memory components to be used per LSM index.

2

storageMemorycomponentPagesize

300

threaddumpLogLevel

The log level at which to emit diagnostic thread dumps.

DEBUG

traceCategories

Categories for tracing.

[ ] (empty array — no categories)

jvmArgs

JVM args to pass to the Analytics Driver. Node-specific JVM arguments are appended to service-level JVM arguments. If the same JVM argument appears in both the service-level arguments and the node-specific arguments, the node-specific argument takes priority.

<undefined> (null)

storageBuffercacheSize

The size of memory allocated to the disk buffer cache. The value should be a multiple of the buffer cache page size.

1/4 of the allocated Analytics Service memory

storageMemorycomponentGlobalbudget

The size of memory allocated to the memory components. The value should be a multiple of the memory component page size.

1/4 of the allocated Analytics Service memory
