Without this, DictionaryArrays produced by different parts of a Parquet file could have different index types depending on the cardinality of each decoded part.

Refactors DictionaryBuilder (which uses AdaptiveIntBuilder) and Dictionary32Builder (which uses Int32Builder) to have a common base class.

@pitrou I haven't done comprehensive benchmarks yet but the main benefit is actually memory use (see example of user running into runaway memory usage on a highly encoded file at https://issues.apache.org/jira/browse/ARROW-5993). Performance should be better, too. I'll run benchmarks to illustrate

BTW @pitrou this patch is also necessary if you want to add dictionary encoding to the CSV reader (because each chunk may have a different dictionary cardinality)

Without this, DictionaryArrays produced by different parts of a Parquet file could have different index types depending on the cardinality of each decoded part.

Refactors DictionaryBuilder (which uses AdaptiveIntBuilder) and Dictionary32Builder (which uses Int32Builder) to have a common base class.

@pitrou I haven't done comprehensive benchmarks yet but the main benefit is actually memory use (see example of user running into runaway memory usage on a highly encoded file at https://issues.apache.org/jira/browse/ARROW-5993). Performance should be better, too. I'll run benchmarks to illustrate

BTW @pitrou this patch is also necessary if you want to add dictionary encoding to the CSV reader (because each chunk may have a different dictionary cardinality)
