FLOAT missing from Literal datatypes, but defined in Column datatypes.

FLOAT is missing from Literal datatypes (org.apache.pinot.common.request.Literal) but defined as a column datatype (org.apache.pinot.spi.data.FieldSpec.DataType). This may create type conversion issues since the only way to specify values for FLOAT column is by using DOUBLE literal values.

Literal defines the following datatypes:
BOOL, BYTE, SHORT, INT, LONG, DOUBLE, STRING, BINARY

FieldSpec.DataType defines the following datatypes:
INT, LONG, FLOAT, DOUBLE, BOOLEAN/* Stored as STRING */, STRING, BYTES, STRUCT, MAP, LIST;

Start by reading org.apache.pinot.common.request.Literal and org.apache.pinot.spi.data.FieldSpec.DataType, then trace how literal types are converted for column values. Confirm the FLOAT datatype is represented consistently and that FLOAT column values no longer require DOUBLE literals, adding or updating relevant conversion coverage.
