Default schema-level TileDB parameters are set to be useful for most users.
If you have particular needs or use-cases, though, you can use the
PlatformConfig
options to override default schema
parameters.
platform_config <- PlatformConfig$new()
platform_config$set('tiledb', 'create', 'dataframe_dim_zstd_level', 8)
platform_config$set('tiledb', 'create', 'sparse_nd_array_dim_zstd_level', 9)
platform_config$set('tiledb', 'create', 'tile_order', 'ROW_MAJOR')
platform_config$set('tiledb', 'create', 'cell_order', 'ROW_MAJOR')
platform_config$set('tiledb', 'create', 'dims', list(
soma_dim_0 = list(filters = list(list(name="ZSTD", COMPRESSION_LEVEL=9)), tile=100000),
soma_dim_1 = list(filters = list(list(name="ZSTD", COMPRESSION_LEVEL=9)), tile=100000),
))
platform_config$set('tiledb', 'create', 'attrs', list(
soma_data_a = list(filters = list("RLE"))
))
tdco <- TileDBCreateOptions$new(platform_config)
This can then be passed to SOMADataFrameCreate
,
SOMASparseNDArrayCreate
, et al.
