firstly isn't duplicate of this question because i'm not behind load balancer @ moment. randomly restarting instance isn't satisfactory solution either. i moved our store using local mysql db on ec2 rds , we're getting errors on backend when they're moving categories around / adding products. sqlstate[hy000]: general error: 1205 lock wait timeout exceeded; try restarting transaction i've seen other variations of pdo errors. how 1 go eliminating these issues? i've read suggestions 'keep retrying' seems stupid. i've tried tinkering innodb_lock_wait_timeout , others doesn't seem resolve it. i have disabled magento logging db - see if helps going forward. unfortunately have wait while let staff tinker on backend , see if fix has effect. thanks update now seeing bunch of these user error: ddl statements not allowed in transactions

in android app plot airports on google maps. when zoomed out far, density gets high. i'm familiar marker clustering libraries, rather have solution distribution of airports shown, leaving out overlapping ones, , when zoom in more airports filled in needed. tips on this. clustering need. you need to: position cluster @ same latlng 1 of markers in cluster use same icon cluster regular markers taking example android maps extensions, i'm familiar with, have modify code in clustermarker.java from private latlng calculateclusterposition() { latlngbounds.builder builder = latlngbounds.builder(); (delegatingmarker m : markers) { builder.include(m.getposition()); } return builder.build().getcenter(); } to like private latlng calculateclusterposition() { return markers.get(0).getposition(); } or bit more sophisticated algorithm, calculates center , iterates on markers again find nearest marker , use position.
