DISABLE_CODEGEN Query Option

This is a debug option, intended for diagnosing and working around issues that cause crashes. If a query fails with an "illegal instruction" or other hardware-specific message, try setting DISABLE_CODEGEN=true and running the query again. If the query succeeds only when the DISABLE_CODEGEN option is turned on, submit the problem to the appropriate support channel and include that detail in the problem report. Do not otherwise run with this setting turned on, because it results in lower overall performance.

Because the code generation phase adds a small amount of overhead for each query, you might turn on the DISABLE_CODEGEN option to achieve maximum throughput when running many short-lived queries against small tables.

Type: Boolean; recognized values are 1 and 0, or true and false; any other value interpreted as false
