```multimaster.cluster_name``` Name of the cluster. If you set this variable,`multimaster` checks that the cluster name is the same for all the cluster nodes.

```multimaster.queue_size``` Multimaster queue size. default = 256*1024*1024

```multimaster.trans_spill_threshold``` Maximal size (Mb) of transaction after which transaction is written to the disk. Default = 100, /* 100Mb*/

```multimaster.max_2pc_ratio``` Maximal ratio (in percents) between prepare time at different nodes: if T is time of preparing transaction at some node, then transaction can be aborted if prepared responce was not received in T*MtmMax2PCRatio/100. default = 200, /* 2 times*/

```multimaster.queue_size``` Multimaster queue size. default = 256*1024*1024,

```multimaster.trans_spill_threshold``` Maximal size (Mb) of transaction after which transaction is written to the disk. Default = 1000, /* 1Gb*/ (istm reorderbuffer also can do that, isn't it?)

```multimaster.vacuum_delay``` Minimal age of records which can be vacuumed (seconds). default = 1.

```multimaster.worker``` Number of multimaster executor workers. Default = 8. (use dynamic workers with some timeout to die?)
