```multimaster.ignore_tables_without_pk``` Do not replicate tables withpout primary key. Boolean.

```multimaster.cluster_name``` Name of the cluster, desn't affect anything. Just in case. If set that mmts will check name correspondence.

(probably we will delete that variables, most of them are useful only for development purposes --stas)

```multimaster.cluster_name``` Name of the cluster, desn't affect anything. Just in case.

```multimaster.min_2pc_timeout``` Minimal timeout between receiving PREPARED message from nodes participated in transaction to coordinator (milliseconds). Default = 2000, /* 2 seconds*/.

```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?)

```multimaster.max_worker``` Maximal number of multimaster dynamic executor workers. (set this to max_conn?) Default = 100.

```multimaster.gc_period```Number of distributed transactions after which garbage collection is started. Multimaster is building xid->csn hash map which has to be cleaned to avoid hash overflow. This parameter specifies interval of invoking garbage collector for this map. default = MTM_HASH_SIZE/10

```multimaster.gc_period``` Number of distributed transactions after which garbage collection is started. Multimaster is building xid->csn hash map which has to be cleaned to avoid hash overflow. This parameter specifies interval of invoking garbage collector for this map. default = MTM_HASH_SIZE/10

```multimaster.max_node``` Maximal number of cluster nodes. This parameters allows to add new nodes to the cluster, default value 0 restricts number of nodes to one specified in multimaster.conn_strings (May be just set that to 64 and allow user to add node when trey need without restart?) default = 0

```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.node_disable_delay``` Minimal amount of time (msec) between node status change. This delay is used to avoid false detection of node failure and to prevent blinking of node status node. default = 2000. (We can just increase heartbeat_recv_timeout)

```multimaster.connect_timeout``` Multimaster nodes connect timeout. Interval in milliseconds for establishing connection with cluster node. default = 10000, /* 10 seconds*/
