> Key: PARQUET-591
> URL: https://issues.apache.org/jira/browse/PARQUET-591
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-cpp

> Currently we start a new page after 1000 rows. Instead we should split pages by their size. Therefore implement a size estimation algorithm and split pages based on its results.
> See also in parquet-column/../column/impl/ColumnWriteStoreV2.java:sizeCheck for the Java implementation.
