| 2014-09-11 | DRILL-1389: Incorrect results when reading nullable data out of parquet | Jason Altekruse | |
| Fixed numerous issues in the nullable reader for parquet, removed some cruft from previous attempts to fix earlier issues that did not properly address the root causes. The reader overall is simpler and cleaner. Verified against a variety of existing a new files with complete result checks comparing against Steven's parquet reader that uses the higher level interface. Wrote some new test tooling to allow for comparisons of large result sets. Re-enabled the fixed binary support that was accidentally removed in some of the last changes before 0.5. Fixed a bug where we were initializing the column data reader to read the uncompressed size of the column chunk, rather than the on-disk size. | |||

| 2014-08-29 | DRILL-1307: add support for fixed binary columns in parquet reader. | Jason Altekruse | |
| DRILL-1314: Fix issue reading impala produced files DRILL-1304: Regression selecting a single column from a parquet file. Fixed issue with var length dictionary reading. Reduced memory usage by freeing buffers after we finish reading a page (except for dictionary pages which need to be kept in memory until the entire row group has been read) Rebased onto merge branch. Successfully backed out the changes that had changed the structure of the nullable column readers. This re-introduced some redundancy but avoided a bug that was holding up the release. Ended up falling back on the higher level reader API, only in the case where we are reading a dictionary column and then the next page is not dictionary encoded. This can be fixed to use the optimized read instead, but it doesn't conform to the overall structure of the current reader and is a bit difficult to fix. | |||

| 2014-08-27 | DRILL-1313: All text mode for json reader | Jason Altekruse | |
| Current implementation handles nulls that appear while in text mode differently depending if they appear in lists or maps. This allows for a null where a list or map is expected to act the same way it does without text mode enabled. For an expected map it just assumes that the field didn't exist, in which case the leaves below become null filled, and for a list it will default to showing an empty list. If we are actually inside of a list, a null in JSON will be treated the same as the string "null", which improves over the previous behavior of just dropping the null value all together, as we do not support null values within any of the repeated primitive vectors currently. Patch has been rebased on top of merge branch. | |||
| 2014-08-27 | DRILL-1283: JSON project pushdown. | Jason Altekruse | |
| Allows for users to avoid reading columns of a JSON file, including those that include elements of JSON that drill does not currently support. This can be used to query a subset of an existing file while avoiding elements like schema changes in some columns or nulls in lists that are currently not compatible with Drill. Patch was revised based on Hanifi's review comments, and then rebased off of the merge branch. | |||
