These versions are stored efficiently on disk optimizing for disk usage. Two additional copies of the most recent version of the matrix are stored in read-optimized form for fast retrieval. +### Row order + +> Probably caused by a mismatch between cases in GN database and the +> genotype file. It would be great to have code that would automatically +> update geno files when we add a sample of known type. + +Currently we are juggling 4 genotype formats and soon a 5th. I agree +that dynamic genotypes would be nice and we will probably have to look +at versioning lmdb for that. If the markers are fixed and we store +individuals as rows that could work. + + ### Encoding LMDB maps octet vector keys to octet vector values. Any data we put into a LMDB database needs to be encoded to octets (effectively aka bytes). genodb supports the following three data types with their respective encodings. |
