Method Detail

engineName

public String engineName()

Query engine name.

Specified by:

engineName in interface org.apache.ignite.internal.processors.query.QueryEngineConfigurationEx

engineClass

public Class<? extends org.apache.ignite.internal.processors.query.QueryEngine> engineClass()

Query engine class.

Specified by:

engineClass in interface org.apache.ignite.internal.processors.query.QueryEngineConfigurationEx

isDefault

public boolean isDefault()

Is this query engine should be used by default.

Specified by:

isDefault in interface QueryEngineConfiguration

Returns:

True if this query engine is default.

setDefault

public CalciteQueryEngineConfiguration setDefault(boolean isDflt)

Sets whether this query engine should be used by default.

There can be only one query engine configuration with the default flag.

If there is no configuration with the default flag, the query engine provided by the ignite-indexing module will be used by default (if configured). If there is no configuration for the ignite-indexing module engine exists, the first engine from the query engines configuration will be used.

Specified by:

setDefault in interface QueryEngineConfiguration

Parameters:

isDflt - True if this query engine should be used by default.

Returns:

this for chaining.

Returns:

Global heap memory quota for SQL engine.

setGlobalMemoryQuota

public CalciteQueryEngineConfiguration setGlobalMemoryQuota(long globalMemoryQuota)

Sets global heap memory quota for SQL engine.

Parameters:

globalMemoryQuota - Global heap memory quota for SQL engine.

getQueryMemoryQuota

public long getQueryMemoryQuota()

Gets per-query heap memory quota.

Returns:

Per-query heap memory quota.

setQueryMemoryQuota

public CalciteQueryEngineConfiguration setQueryMemoryQuota(long qryMemoryQuota)
