Hi Alexander,
I’m parsing the file and storing each row with own key in a map datatype bucket and each column is a register.

Are you 1. uploading the entire file and saving it to one key with the value being the file? Or are you 2. parsing the file and storing each row as a register in a map? Either of those approaches are not appropriate in Riak KV. For the first case I would point you to Riak S2 which is designed to manage large binary object storage. You can keep the large file as a single addressable entity and access it via Amazon S3 or Swift protocol. For the second case I would consider maintaining one key (map) per row in the file and have a register per column in the row. Or not use Riak data types (maps, sets, registers, flags and counters) and simply keep each row in the file as a KV in Riak either as a raw string or as a serialized json string. ETL'ing out of relational databases and into Riak is a very common use case and often implemented in the fashion I described. As Chris mentioned, soft upper bound on value size should be 1MB. I say soft because we won't enforce it although there are settings in the config that can be changed to enforce it (default 5MB warning, 50MB reject I believe.)

Typically we recommend that you try to structure your objects to around 1mb or less to ensure consistent performance. That max object size can vary of course based on your network / server specs and configuration. I hope this helps.

I switched to a map bucket data type with registers. It is taking about 3 times longer to insert into this bucket vs non data typed bucket. Any suggestions?
