* SERVER-60461 Compression support for sub-objects in BSON Column (type 7)Henrik Edin2021-10-206-187/+1243
| | | | | | | | | | | | | | BSONColumnBuilder refactored to put compression logic in EncodingState class to allow for multiple encoding states at once in the case for sub-object compression where each scalar sub-field is compressed individually. The compression of Objects is done in two phases: 1. Determine optimal reference-object 2. Compression of objects using reference-object To determine reference-object we need to traverse incoming Objects that we need to compress that they match the BSON hierarchy of the reference-object determined so far. To match fields must be in the same order and not differ on being of Object type or an empty object. Fields may be missing in the object to compress vs the reference object. When a compatible change is detected a new reference object is built by merging in the change. If an incompatible change is detected we end previous sub-object compression and start over. The control bytes in the BSON Column binary are interleaved and belong to separate EncodingState's for separate sub-field streams. They are written in the order they are needed for decompression. When a DecodingState has depleted its current control block for values it reads the next interleaved block from the binary.

* SERVER-58580 Decoding support for compressed subobjects in BSONColumnHenrik Edin2021-10-133-186/+981
| | | | | | | | | | BSONColumn has been refactored to put the decoding state into a DecodingState class. A new control byte in the data stream has been added for entering "interleaved" mode where sub-elements are compressed separately. One DecodingState is set up for each scalar element in the reference interleaved Object. When decompressing we extract one value from each state to build the full BSONObj to return. We always scan in a fixed order. Control bytes in the binary stream corresponds to the DecodingState that needs to read the next value.

| | | | | | | | | | | | All fields under data will be compressed using BSON Binary Subtype 7. Measurements are sorted by time field. Buckets are compressed in a separate update operation when the BucketCatalog is closing the bucket and no further writes to it will be performed. Compression operation are transparant for the user, if it fails for any reason the bucket will be left uncompressed.

| | | | | | Doubles are scaled and rounded to closest integer. When a double is appended that needs to be scaled differently the encoder validates if flushing simple8b or re-scaling compresses best. After writing a finalized simple8b block, the scaling is reduced to be as low as possible.
