Increase MAX_INDEX on a table

Hi All,

Our devs just reported experiencing adding index on a table, as it hit the maximum number of indexes ( 64 ). Browsing for a solution, found that i need to recompile.

Since we used percona’s deb repository, i also grabbed the source there: apt-get source percon-server-server

After grabbing the source, i updated the file: CMakeLists.txt and edited the line SET(MAX_INDEXES 64) and change to 255, and build the package using dpkgbuild.

but i encountered this error:

---- make[3]: Entering directory `/usr/local/src/percona-server-5.6-5.6.23-72.1/debug’
In file included from /usr/local/src/ppercona-server-5.6-5.6.23-72.1/sql/sql_select.h:31:0,

Sorry im not familiar with C/C++ now i’m stuck :frowning: …hope someone can direct me to a solution. TIA.


Hi nhadie;

Unfortunately I cannot help with changing the code, as that is a lot more involved than most people will ever get to. But have you already checked for duplicate indexes? Chances are if you have 64 indexes already, you have at least a few duplicates.


Thank you Scott. Will look into that.
