Field Detail

DELIMITED_FORMAT_MAX_LINE_SAMPLES

public static final ConfigOption<Integer> DELIMITED_FORMAT_MAX_LINE_SAMPLES

The maximum number of line samples taken by the compiler for delimited inputs. The samples are used to estimate the number of records. This value can be overridden for a specific input with the input format’s parameters.

DELIMITED_FORMAT_MIN_LINE_SAMPLES

public static final ConfigOption<Integer> DELIMITED_FORMAT_MIN_LINE_SAMPLES

The minimum number of line samples taken by the compiler for delimited inputs. The samples are used to estimate the number of records. This value can be overridden for a specific input with the input format’s parameters.

DELIMITED_FORMAT_MAX_SAMPLE_LEN

public static final ConfigOption<Integer> DELIMITED_FORMAT_MAX_SAMPLE_LEN

The maximal length of a line sample that the compiler takes for delimited inputs. If the length of a single sample exceeds this value (possible because of misconfiguration of the parser), the sampling aborts. This value can be overridden for a specific input with the input format’s parameters.
