Options
- array_name
TileDB array to write to. Synonymous with filename. [Required]
- config_file
TileDB configuration file. [Optional]
- data_tile_capacity
Number of points per tile. Not used when append=true. [Optional]
- x_tile_size
Tile size (x). Not used when append=true. [Optional]
- y_tile_size
Tile size (y). Not used when append=true. [Optional]
- z_tile_size
Tile size (z). Not used when append=true. [Optional]
- time_tile_size
Tile size (time). Not used when append=true. [Optional]
- x_domain_st
Domain minimum for x. Not used when append=true. [Optional]
- x_domain_end
Domain maximum for x. Not used when append=true. [Optional]
- y_domain_st
Domain minimum for y. Not used when append=true. [Optional]
- y_domain_end
Domain maximum for y. Not used when append=true. [Optional]
- z_domain_st
Domain minimum for z. Not used when append=true. [Optional]
- z_domain_end
Domain maximum for z. Not used when append=true. [Optional]
- time_domain_st
Domain minimum for GpsTime. Not used when append=true. [Optional]
- time_domain_end
Domain maximum for GpsTime. Not used when append=true. [Optional]
- use_time_dim
Use GpsTime coordinate data as an array dimension instead of an array attribute. Not used when append=true. [Optional]
- time_first
Put the GpsTime dimension first instead of last. Only used when use_time_dim=true. Not used when append=true. Default is false. [Optional]
- chunk_size
Point cache size for chunked writes. [Optional]
- compression
The default TileDB compression filter to use. Only used if the dimension or attribute name is not included in filters. Not used when append=true. Default is None. [Optional]
- compression_level
The TileDB compression level to use for the default compression. Option is ignored if set to -1. Not used when append=true. Default is -1. [Optional]
- append
Instead of creating a new array, append to an existing array that has the dimensions stored as a TileDB dimension or TileDB attribute. Default is false. [Optional]
- stats
Dump query stats to stdout. [Optional]
- filters
JSON array or object of compression filters for either dims or attributes of the form {dim/attributename : {“compression”: name, compression_options: value, …}}. Not used when append=true. [Optional]
- timestamp
Sets the TileDB timestamp for this write. [Optional]
- where
An expression that limits points passed to a writer. Points that don’t pass the expression skip the stage but are available to subsequent stages in a pipeline. [Default: no filtering]
- where_merge
A strategy for merging points skipped by a ‘where’ option when running in standard mode. If
true
, the skipped points are added to the first point view returned by the skipped filter. Iffalse
, skipped points are placed in their own point view. Ifauto
, skipped points are merged into the returned point view provided that only one point view is returned and it has the same point count as it did when the writer was run. [Default:auto
]
By default TileDB will use the following set of compression filters for coordinates and attributes;
