8098

Port to query Pinot Server

pinot.server.netty.host

pinot.server.instance.id

By default the server instance id used by Helix is Server_hostname_port where the hostname and port are configured through host and port config values above. This config overwrites the default setting. User can put server id independent of the server's hostname and port.

pinot.server.instance.dataDir

java.io.tmpdir + /PinotServer/index

Directory to hold all the data

pinot.server.instance.consumerDir

pinot.server.instance.segmentTarDir

Directory to hold temporary segments downloaded from Controller or Deep Store

pinot.server.instance.readMode

mmap

pinot.server.instance.reload.consumingSegment

true

Specifies if the reload segment API should reload the consuming segments. This is useful when the corresponding schema is updated and we want the changes to be reflected in the consuming segment.

pinot.server.instance.data.manager.class

org.apache.pinot.server. starter.helix.HelixInstanceDataManager

pinot.query.scheduler.name

fcfs

Currently only FCFS (first-come-first-serve) is supported

pinot.query.scheduler.query_runner_threads

CPU cores

Main thread to execute the queries (one thread per query)

pinot.query.scheduler.query_worker_threads

2 * CPU cores

Worker thread to process the segments (multiple threads per query)

pinot.query.scheduler.query.log.maxRatePerSecond

unlimited

Maximum queries to be logged per second. Queries with exceptions and costly queries are always logged.

pinot.server.query.executor.class

pinot.server.query.executor.pruner.class

ValidSegmentPruner,DataSchemaSegmentPruner, ColumnValueSegmentPruner,SelectionQuerySegmentPruner

pinot.server.query.executor.timeout

15000

Timeout for Server to process Query in Milliseconds

pinot.server.query.executor.max.execution.threads

-1 (unlimited)

Maximum number of execution threads allowed for a query. Limiting this can prevent a single expensive query from occupying all the execution threads.

pinot.server.query.executor.max.init.group.holder.capacity

10000

Initial capacity of the group key holder. Increasing this value can reduce the resizing of the group key holder, but increase the heap usage for small group-by queries.

pinot.server.query.executor.num.groups.limit

100000

Maximum number of groups kept from each segment during query execution. Once this limit is reached, no more groups will be taken (will still aggregate on existing groups).

pinot.server.query.executor.min.segment.group.trim.size

-1 (do not trim)

Minimum number of groups kept at segment level during query execution. If there are enough groups found in a segment, pinot will trim the groups to max(5 * LIMIT, minSegmentgroupTrimSize) groups based on the order-by clause. Increasing this value can increase the accuracy of the results, but also increase the heap usage of the group-by queries.

pinot.server.query.executor.min.server.group.trim.size

5000

Minimum number of groups kept at server level during query execution. If there are enough groups found in a server, pinot will trim the groups to max(5 * LIMIT, minServergroupTrimSize) groups based on the order-by clause. Increasing this value can increase the accuracy of the results, but also increase the heap usage and data transfer cost of the group-by queries.

pinot.server.query.executor.groupby.trim.threshold

1000000

Threshold for number of groups to trigger the server group trimming. Increasing this value can reduce the times of trimming, but also increase the heap usage of the group-by queries.

pinot.server.instance.realtime.max.parallel.segment.builds

0

Specifies how many parallel real-time segments can be built. Value of <= 0 indicates unlimited.

pinot.server.instance.realtime.alloc.offheap

false

Boolean value to control whether memory for real-time consuming segments should be allocated off-heap.

pinot.server.instance.realtime.alloc.offheap.direct

false

If 'real-time.alloc.offheap' is set to true, this boolean value controls whether the corresponding allocation should be direct or not (false indicate mmap allocation)

pinot.server.startup.minResourcePercent

100

The percentage of tables that need to be in an ONLINE state before the server is marked as STARTED to server queries

pinot.server.startup.timeoutMs

10 minutes

The total amount of time a server will wait for all status checks before server is marked as STARTED to server queries

pinot.server.starter.realtimeConsumptionCatchupWaitMs

0

On it's own, this is a static amount of time servers will wait for consuming segments before server is marked as STARTED to server queries When paired with pinot.server.starter.enableRealtimeOffsetBasedConsumptionStatusChecker or pinot.server.starter.enableRealtimeFreshnessBasedConsumptionStatusChecker, this is how long those status checkers will wait for segments to turn GOOD This should not be set to more than pinot.server.startup.timeoutMs as it will not be respected

pinot.server.starter.enableRealtimeOffsetBasedConsumptionStatusChecker

false

When true, the server will collect the current, latest offsets for all consuming segments and will mark those segments as GOOD once they have caught up to those offsets

pinot.server.starter.enableRealtimeFreshnessBasedConsumptionStatusChecker

false

When true, the server will not be marked as STARTED or serve queries until

1) the server has caught up to the latest available offset or the latest consumed event for each segment is at least within pinot.server.starter.realtimeMinFreshnessMs of the current time 2) pinot.server.startup.timeoutMs has elapsed

pinot.server.starter.realtimeMinFreshnessMs

10 seconds

When pinot.server.starter.enableRealtimeFreshnessBasedConsumptionStatusChecker=true, this configures the minimum freshness (now - last_event_time) for the server status checker to consider a consuming segment GOOD

This only applies when pinot.server.starter.enableRealtimeFreshnessBasedConsumptionStatusChecker=true

pinot.server.starter.realtimeFreshnessIdleTimeoutMs

0

When pinot.server.starter.enableRealtimeFreshnessBasedConsumptionStatusChecker=true, this will mark a segment as GOOD after this timeout if it has not consumed any events.

pinot.server.startup.exitOnServiceStatusCheckFailure

false

When true, the server will shutdown after pinot.server.shutdown.timeoutMs rather than be marked as STARTED if the status has not turned GOOD

pinot.server.startup.enableServiceStatusCheck

true

true - server will run all configured checks false - server will be marked as STARTED without performing an startup checks
