When you make comments to this blog, it asks for a simple maths sum
I got one asking for 0 + 8, but it wouldnt accept 8 as the answer

I had to refresh the page to get a diff sum. Trivial I know, but I thought Id mention it

I’m working with a few tables for a small trading company (but somehow manage to do tons of transaction daily TT.TT)
I required to display combination of data from 3 or more table
at first before I read through your article and others in the net, it take the computer if not 10-30 minutes to complete the display
now it only took roughly about 1 minute with the computer stopped for that time period (which is still unsatisfactory for me)
could you give me information whether it is the maxed capabilities of MySQL or could I improve it more (if so we might need to consult with you )

here’s the condition:
1 table with 15 column and 3000+ data (product)
1 table with 9 column and 1000+ data (sales)
1 table with 10 column and 3000+ data (sales detail)

I need to display data from each table combined into 1 display (sales, sales detail, product detail)
unfortunately I’m using VB6 (continuing their old system) should I recommend them to use other language?
we are also using standard PC (no server) core 2 duo 2ghz, 2gb ram to host the database and application all together

I know this is quiet a bad forum to post such a question though I’m hoping you gain a quick point of view from you or someone else from Percona with regards to Continuent’s Tungston replicator as a drop in replacement for MySQL standard master / slave.

In a scenario where theres no funky binlog excludes to purge out DROPS or what not from slaves, as far as I can tell, the only real benefit is the ability to have a multiple slave configuration and the ability to promote a slave to a master and have those other slaves be fully aware of where I am at this point of time with regards the new master.

I am wondering what your thoughts are on Continuent’s Tungston replicator? Have you had many customers use it?

Thanks and again I find these posts and book most informative.

Kind regards,
