It's surprising that MySQL Cluster can do 589k reads per second on a dual core i5 machineIn a previous post (http://mikaelronstrom.blogspot.com/2015/03/200m-reads-per-second-in-mysql-cluster.html) you wrote "now each API node can process more than1M http://markmail.org/message/7g7yqemhkt2xdvrz When rolling back a multiple-operation transaction having concurrent delete and insert operations on the same record, the abort arrived first for the delete operation, and then for the insert.

So far the problem persists, so I disable memlock in the config.ini. The CPU is an Intel Core i5-4250 CPU. started ndb_mgmd using mcm. 6.

When I look at the processlist I notice that there appears to be process that seems to be blocking.

the LOCK_OPEN lock normally protecting mysqld's internal table list is released so that other queries or DML statements are not blocked. Note The maximum number of attributes supported per table is not the same for all MySQL Cluster releases. Here the information about physical memory inthe node:$ freetotal used free shared buffers cachedMem: 49555124 41853912 7701212 0 143192 1330260-/+ buffers/cache: 40380460 9174664Swap: 390624248 0 390624248is that with a running data Reads are about as fast with recoverability as without.

A problem was encountered in the mechanism intended to keep the current epoch open which led to a race condition between this mechanism and that normally used to declare the end Bugs FixedIncompatible Change; Cluster API: The default behavior of the NDB API Event API has changed as follows: Previously, when creating an Event, DDL operations (alter and drop operations on tables) If yes, how did you do it? this contact form start mysqld using mcm 8.
