Reducing the block\nsize reduces the memory use at the expense of a bit of read inefficiency.\nThis choice (200 rows, for a 4k patch width) should give us plenty of\nroom for growth.\n\nTo attempt to gain back some read efficiency, use full rows (the 10k\nwidth set here is much larger than the typical patch size).\n\nImplemented as an obs_subaru override instead of changing the default in\npipe_tasks because the default is fine for most other applications.","distinct":true,"url":"https://api.github.com/repos/lsst/obs_subaru/commits/b14dceb83e3cd56f67c6db9ad56bc803879306b7"}]}
