Subject: [PATCH 057/270] Ordinals stored delta have a fixed sorting order. 1.
 Ordered on absolute value 2. For equal absolute value, ordinal meant for
 update is greater than ordinal meant for incremental insert.

Also duplicate elimination only happens for ordinals meant for update.

Subject: [PATCH 092/270] Performance and misc fixes in smart connector

- move the getDeletedRowCount() call in ColumnTableScan to be after the stats row filtering
  else it leads to all projected buffers to be fetched for smart connector
- check if Spark is using IP addresses in smart connector cluster, and if so then
  extract the address portion from the returned bucket-server mapping instead of
  using host names so that NODE_LOCAL routing happens for connector jobs
- set the default shuffle partitions to be defaultParallelism (which uses the total cores in system)
  with an upper cap of the Spark setting
- clear plan cache when shuffle partition setting changes to enable it be applied on all plans
- fixed a missing release of storage memory in smart connector iterator after decompression
  when the decompressor has acquired new buffer (using ByteOrder as an indication in
      the returned buffer whether it was decompressed or not)

Subject: [PATCH 095/270] Revert this change.

Now do away condition where a column btach is not filtered out if it has some updated columns.

However, in lack of proper stas for update some of queries fails. But still checkin it for permance reasons.

Subject: [PATCH 114/270] [SNAP-2243][SNAP-2188] procedure for smart connector
 iteration and fixes

Includes the changes for the two issues and a bunch of other fixes found in testing.

- Implementation of StoreCallbacks.columnTableScan that translates Filters to Expressions
  and generates the code to apply the same locally to ColumnBatchIterator stats rows
- Changed smart connector iterator to use the new COLUMN_TABLE_SCAN procedure instead
  of multiple queries.
- Added passing of Filters to the plans and recreation of those in getPartitions if
  the parameter values have changed for ParamLiterals
- Fixed RowFormatScanRDD to regenerate filter clause in getPartitions if the parameter
  values have changed for ParamLiterals (not seen earlier because index columns were
    incorrect which has been fixed in store)
- Perf fix to ColumnFormatIterator: keep track of updated delta stats separately with
  forced faultin like the full stats in DiskMultiColumnBatch so that entire batch does
  not need to be read if filter can skip using stats
- Perf fix to RemoteEntriesIterator:
  - fetch both full stats and delta stats rows when fetching keys first time
  - sort and ensure both rows of a batch are together when fetching other columns
- Updated ParamLiteral serialization to replace its value with the updated one in LiteralValue
  since parameter may have changed (but the base Literal.value is a val and cannot be changed)
- Corrected RDD to be cleared in CachedDataFrame to use either the cachedRDD or the
  last used one for execution.
- Added handling of the new DECOMPRESS_IF_IN_MEMORY fetch type to return self (or null)
  if decompression cannot replace the underlying in-memory value
- Updated ColumnFormatValue to store disk RegionEntry instead of diskId since latter can change.
- Improved performance of Snappy stats iterator to avoid lookup of deleted bitmask column for every
  stats column, rather iterate both of them and add negative size for deletes if any.
- Added more transient expected exception types to SnappyTestRunner.
- Updated store link.

From c461959514c3291b534335cf054b2d78274f0ce5 Mon Sep 17 00:00:00 2001
From: Sumedh Wale <swale@snappydata.io>

Subject: [PATCH 116/270] changed Filters to Expressions in Relation APIs

- primary reason being that StringStartsWith Filter requires a string as pattern
  and cannot hold "Any" so the hack of stuffing in a ParamLiteral inside Filter
  does not work; now using Expression which are translated to Filter just before use if required
- pushdown of filters from smart connector to server still uses Filter after conversion
  from Expression and when the ParamLiterals have been substituted with current values
- removed awkward handling of ParamLiterals inside Filters as a result of above changes
- fixed the StartsWith stats filter to use a ParamLiteral and generated code for the
  comparison against stats row bounds

Subject: [PATCH 124/270] [SNAP-2244] stats for delta column batches

- Add delta column stats with same format/schema as full stats. Columns that have seen
  no updates will have the three fields set as null (so cost 3 bits in UnsafeRow).
- Refactored stats generation in ColumnInsertExec to move into object for use by update
  and also removed explicit handling for wide-column schema. Now the full code for stats
  is not generated in one shot rather each column variable holds own code so the
  GenerateUnsafeProjection code generation will split automatically if required.
- Added update delta stats row generation using above in ColumnUpdateExec.
- Added merge of multiple delta stats as part of ColumnDelta.apply.
- Refactored CodeGeneration a bit to allow for code generation of UnsafeProjection for above
  merge code that needs to write the final merged UnsafeRow.
- Removed checks/add of delta stats in delete bitmask column which was never required since
  delete bit mask is fetched separately in any case after all stats checks are done
  (and will lead to read of all projected columns).
- Skip any pushed down filters on column types that do not maintain stats (e.g. calendar, complex types)
- Added delta stats count in ColumnTableScan and stats service (ColumnFormatKey.getColumnBatchRowCount)
