I was a software developer at Tokutek working on TokuDB. If I wanted to continue working on TokuDB, Tokutek had to make money to pay for the expenses of running a company. Supporting TokuDB on Windows led to absolutely no business, so why would I want to waste time supporting it? We would jump

Mariadb should understand the comparison between Myrocks and Tokudb, and let their current users decide what should be in the product. It is their product and their responsibility. Unfortunately, I am no longer working on database software as my primary focus, so I can not make any significant

Hello All, Back in the day, I was one of the Tokudb developers @ Tokutek. Two of the features that I worked on were read free replication (RFR) and online schema change for Tokudb. RFR has some nice slave performance benefits by the replacing read modify write algorithm with a write algorithm.

Hello All, I have been running sysbench oltp with a mariadb 10.1 master-slave topology. I have not seen any replication errors when slave parallel mode is conservative. However, when I configure slave parallel mode to optimistic and slave parallel threads = 2, I get a lock timeout replication

as it would close all of the holes. In addition, there probably is some bug in the interaction between the MySQL server and TokuDB WRT table creation and deletion that may need to be fixed. However, I was unable to find this bug when working at Tokutek. > On Aug 02, Rich Proha

[Maria-discuss] Orphaned TokuDB tables

2016-08-02 Thread Rich Prohaska
Hello All, Sometimes, TokuDB gets left in a state where it thinks that parts of a table exist (as observed in TokuDB's file map), but not all of the underlying files (the TokuDB data files and/or the frm file) exist. This probably occurs due to the interaction between the non-transactional DDL
