Query Options

Use table/broker level timeout

enableNullHandling

Enables advanced null handling. See Null value support for more information.(introduced in 0.11.0)

false (disabled)

explainPlanVerbose

Return verbose result for EXPLAIN query (introduced in 0.11.0)

false (not verbose)

useMultistageEngine

Use multi-stage engine to execute the query (introduced in 0.11.0)

false (use single-stage engine)

maxExecutionThreads

Maximum threads to use to execute the query. Useful to limit the resource usage for expensive queries

Half of the CPU cores for non-group-by queries; all CPU cores for group-by queries

numReplicaGroupsToQuery

When replica-group based routing is enabled, use it to query multiple replica-groups (introduced in 0.11.0)

1 (only query servers within the same replica-group)

minSegmentGroupTrimSize

Minimum groups to keep when trimming groups at the segment level for group-by queries. See

Server level config

minServerGroupTrimSize

Minimum groups to keep when trimming groups at the server level for group-by queries. See

Server level config

skipIndexes

Which indexes to skip usage of (i.e. scan instead), per-column. This is useful for side-by-side comparison/debugging. There can be cases where the use of an index is actually more expensive than performing a scan of the docs which match other filters. One such example could be a low-selectivity inverted index used in conjunction with another highly selective filter.

Config can be specified using url parameter format: skipIndexes='col1=inverted,range&col2=inverted'

Possible index types to skip are: sorted, range, inverted, H3. To find out which indexes are used to resolve a given query, use the EXPLAIN query.

null/empty (use all available indexes)

skipUpsert

For upsert-enabled table, skip the effect of upsert and query all the records. See Stream ingestion with Upsert

false (exclude the replaced records)

useStarTree

Useful to debug the star-tree index (introduced in 0.11.0)

true (use star-tree if available)

AndScanReordering

See detailed description

disabled

maxRowsInJoin

Configure maximum rows allowed in join hash-table creation phase

default value read from cluster config

if not set, the default will be

2^20 (1024*1024)

inPredicatePreSorted

(Only apply to STRING columns) Indicates that the values in the IN clause is already sorted, so that Pinot doesn't need to sort them again at query time

false (values in IN predicate is not pre-sorted)

inPredicateLookupAlgorithm

(Only apply to STRING columns) The algorithm to use to look up the dictionary ids for the IN clause values.

• DIVIDE_BINARY_SEARCH: Sort the IN clause values and do binary search on both dictionary and IN clause values at same time to reduce the value lookups

• SCAN: Sort the IN clause values and scan both dictionary and IN clause values to get the matching dictionary ids

• PLAIN_BINARY_SEARCH: Do not sort the IN clause values, but directly binary search each IN clause value in the dictionary

DIVIDE_BINARY_SEARCH

maxServerResponseSizeBytes

Long value config indicating the maximum length of the serialized response per server for a query.

Overriding priortiy order: 1. QueryOption -> maxServerResponseSizeBytes

2. QueryOption -> maxQueryResponseSizeBytes

3. TableConfig -> maxServerResponseSizeBytes

4. TableConfig -> maxQueryResponseSizeBytes

5. BrokerConfig -> maxServerResponseSizeBytes

6. BrokerConfig -> maxServerResponseSizeBytes

maxQueryResponseSizeBytes

Long value config indicating the maximum serialized response size across all servers for a query. This value is equally divided across all servers processing the query.

Overriding priortiy order: 1. QueryOption -> maxServerResponseSizeBytes

2. QueryOption -> maxQueryResponseSizeBytes

3. TableConfig -> maxServerResponseSizeBytes

4. TableConfig -> maxQueryResponseSizeBytes

5. BrokerConfig -> maxServerResponseSizeBytes

6. BrokerConfig -> maxServerResponseSizeBytes
